The BIG Trick for Photo Album Use on the Registry is.....
After you have selected 800 or 400 or other pixels using Paint (or other photo pixel resize software) on your computer and applied to any photo on your computer....and after you have uploaded that photo to your Registry Album of Albums.
Once the photo is in your Registry Album (resized by PAINT on your computer) you go to that Album and LEFT Click on the photo....It will then appear the size you PAINTED. You then select and copy the BB Code. Then Paste the BB Code into a post.
Another way is to LEFT Click on the photo......It will then appear the size you PAINTED. You then right Click and Select Copy. Left Click on Insert Image in the Post Heading and Paste the Copy in the Insert Image Box. Click on OK and the image will be Inserted where your curser was set before you selected Insert Image.
Improvements In Solutions.
A significant reorganization of -Solutions- has been accomplished and includes eight continuous posts of regorganized Headings.
The reorganization makes it easier to obtain specific technical information as required.
Mar 5th 2012 - -Solutions- (http://www.zr1.net/forum/showthread.php?t=16778) has been modified considerably in appearance (The Second Generation) by using Link Names for all references.
Link Names show up as (Underlined Descriptions) which you can Left Click to upload the reference.
Aug 24th 2012 - -Solutions- (http://www.zr1.net/forum/showthread.php?t=16778) has been modified considerably in organization (The Third Generation) by reorganizing -Solutions- (http://www.zr1.net/forum/showthread.php?t=16778) into 8 Posts with many additional Link Name References.
Apr 2013 - -Solutions- (http://www.zr1.net/forum/showthread.php?t=16778) has been upgraded (The Fourth Generation) with all thread/post references checked and verified. Some posts in threads had been deleted and/or photos in posts hosting photo web sites not maintaned.
Aug 2013 - CF -Solutions- (http://forums.corvetteforum.com/c4-zr-1-discussion/3005470-tech-info-lt5-modifications-rebuild-tricks-500-hp-6.html#post1583616056) were expanded and made identical to the Registry Forum -Solutions- (http://www.zr1.net/forum/showthread.php?t=16778). Both are being maintained equally :thumbsup:
A post on this Forum cannot exceed 30,000 characters. This limitation in post characters required reorganization
of -Solutions- posts to meet this requirement. Any word or group of words underlined are left clickable Links.
Many who post on this Forum no longer use Photobucket. Many of those original posts using Photobucket have lost the photos.
Those posts are gradually being replaced with posts that do show associated photos for clarity.
See Solutions (http://www.zr1.net/forum/showthread.php?t=11619) on how to copy a functional (with left clickable references) -Solutions- to a WORD Document on your computer.

LT5 Bolt Charts with suggested bolt torque, loctite and antiseize application information are included above. The free chart from Jerry's Gaskets which provided the basic LT5 component bolt sizes has been considerably modified into two charts above. The charts have been organized by function.

Aluminum Stat-O-Seal washers with molded Buna-N inner seals are much more reliable than the more common steel stat-o-seals. If the rubber portion fails to make contact all around the port, the aluminum will act as a crush washer, providing a reliable metal to metal seal. Use them to seal screws, bolts or plumbing fittings. The Buna-N seal is resistant to petroleum fuels and oils.

The best tool for cutting the SS Braided Hose is a Small Angle Grinder (with Cut Off wheel) which does not fray the SS braids on the hose ends. It is also best to use an appropriate size Box Wrench on the Hose Fittings (box end) to minimize leaving marks on the fittings. I use Aeroquip Reusable Fittings and SS Braided hose from Summit Racing (http://www.summitracing.com/).
https://cimg3.ibsrv.net/gimg/www.corvetteforum.com-vbulletin/400x300-1/80-8ddc4dc6_297b_40b9_a1a9_12d5ca7baf00_1__353c25ffb0 7c9b33ea141a538e4a03e9246160ff.jpg
To remove existing 12AN x 3/4 NPT fittings from the Oil Filter Housing use a 1 inch box wrench (combination box/open end) with the box end on the fitting interlocked with a 3/4 inch box wrench on the other end. This will provide the leverage/torque without excessive horizontal pressure to remove the fittings. I use permatex when installing the New 10AN x 3/4 inch NPT fittings into the Oil Filter Adapter (lower fitting first). Let the ZR-1 sit over night before removing the existing Oil Cooler Hoses to minimize oil spilling.
Use of 10AN Hose/Fittings (https://www.corvetteforum.com/forums/c4-zr-1-discussion/3917585-oil-cooler-line-leaking-where-to-get-a-new-one-2.html#post1593689383)
I use all 10AN Aeroquip Reusable Fittings and 10AN Hose....The 10AN SS Braided hose I use has ID of 9/16 inch and the 12 AN SS Braided Hose has ID 5/8 inch. As it turns out.....the 12AN hose with 5/8 inch ID is identical to stock Oil Cooler Hose having ID of 5/8 inch. Also I noted the ID Fittings on the stock Oil Cooler Hoses on the Oil Cooler end where the tubing is located is less ID than the SS Braided 10AN Oil Lines.
The Stock Oil Cooler hoses have 6 inches of steel tubing on Oil Cooler end that are identical in ID (9/16 inch) to SS Braided 10AN. Further, the Stock Oil Cooler hoses are 17 inches long as compared to 13 inches long for SS Braided Oil Cooler Hoses. The Oil Filter Adapter end of the Stock Oil Cooler hoses is only about 1/2 inch ID at the fittings. Which if you add all that up I would say the total head loss in the stock Oil Cooler hoses is about identical to the SS Braided 10AN with Aeroquip 10AN Fittings.
2. Measuring SS Braided Hose Length.
A. Follow Step #3 below and make up one end of each SS Braided Hose (cut longer than required to reach the Oil Cooler Adapter) with the 45 degree Aeroquip Reusable Hose Ends.
B. Install and snug up but not tight the 45 degree Aeroquip 10AN Hose ends onto the 10AN x 3/4 inch NPT fittings installed into the Oil Filter Adapter.
C. Take the free SS Braided Hose ends curved freely around the radiator housing as they would look in the final installation. Mark the SS Braided Free Hose Ends along Red Line A and Red Line B as shown.
D. Cut these Hose Ends about 1/4 inch longer than that mark.
E. Install the 90 degree Aeroquip 10AN hose ends as in step #3 below.
F. After installation of all four 10AN Aeroquip hose ends is complete, install the 90 degree hose ends on the Oil Cooler Adapter.
G. Tighten the 10AN Fittings into the Oil Cooler Adapter (18mm x 1.5 or 6AN Straight Fittings).
H. Tighten the 10AN 90 degree Aeroquip Fittings onto the 10AN male fittings of the Oil Cooler Adapter at the angles shown by CD and EF.
Make sure there is a small gap between the bottom 10AN 90 Degree Fitting and the AC Line and the two 10AN 90 degree fittings (top and bottom)
I. Install the other end of the SS Braided Hoses 45 degree Aeroquip Fittings onto the respective Oil Filter Adapter male fittings and tighten.
J. Now making sure the "O" rings are in place on the Oil Cooler Adapter (I use Permatex on the adapter "O" ring face), position and the adapter on the face of the Oil Cooler and insert the 6mm x 1.0 x 35 mm SS Allen head bolt with SS washer into the Oil Cooler Adapter and tighten the bolt. No modification of the Fiberglass Radiator Housing is required since the Oil Cooler Adapter is installed on the Oil Cooler AFTER the fittings are connected and tightened on the Oil Cooler Adapter.

3. General SS Hose Assembly with Re-Usable Fittings.
A. Place SS Braided hose in vice and cut SS Braided hose to length using Angle Grinder with Cut Off wheel. Angle grinder is preferred since minimal SS wires are left free of the cut.
B. Make sure NO SS Braided wires enter the hose end and make sure ALL loose SS Braided wires are ground flush with end of hose. Keep the hose in the vice with about 2 inches on the free end out of the vice. (Clean the inside of the hose end Cut Off before going further with Cotton Cue Tip .
C. Take the AN reusable hose fitting and unscrew the male part from the female part. The other end of the male part will have an NPT pipe thread or "O" ring seal thread size (AN) as desired.
D. Take the AN reusable hose fitting female part and screw/push onto the SS Braided hose (counterclockwise) by hand pushing onto the hose as you rotate the female hose fitting counterclockwise. Aeroquip Nickel Plated Aluminum Reusable Fittings are not threaded but ARE serrated requiring a push onto the hose only. Make sure ALL SS Braids are inside the hose fitting just pushed onto the hose.
E. Screw/push the AN female reusable hose fitting onto the hose fitting such that the hose is at a depth into the female fitting as defined by the lines on the female fitting surface.
F. Lubricate the inside diameter of the SS Braided hose with oil through the end of the female fitting.
G. Insert the male reusable hose fitting into the lubricated hose through the end of the female fitting.
H. Push the male fitting into the hose as you rotate the male fitting clockwise using a cresent wrench (Box Wrench preferred). Once the threads are caught, continue rotating the male fitting into the hose untill approximately 1/16 inch space is left between the hexigon of the male fitting and female fitting.
I. Install the second hydraulic reusable hose fitting on the other end of the hose as per steps 2 through 8 above.
J. Last...but not least....take an air hose (Air Compressor) and blow the hose clear to make sure you have a clean assembly (if the SS Braided hose is not too long look through the hose end to end for any debree). You now have a SS Braided hydraulic hose with fittings good for maybe 2,000 psi hydraulic pressure more or less.
4. Parts Required for SS Braided Oil Cooler Lines with Re-Usable Fittings.
The SS Oil Cooler Lines are very easy to make up in SS Braided hose using Aeroquip reusable fittings and SS Braided hose available from Summit Racing (http://www.summitracing.com/). The Aeroquip Fittings are Swivel so self aligning when installing.
A. Use two 10 AN Stainless Steel Braided hose (http://www.summitracing.com/parts/sum-230003/overview/)
B. use two Aeroquip Reusable Hose Ends, 90 Degree, -10 AN Hose to Female -10 AN, Aluminum, Nickel Plated (http://www.summitracing.com/parts/aer-fbe4034)
C. Use two Aeroquip Reusable Hose Ends, 45 Degree, -10 AN Hose to Female -10 AN, Aluminum, Nickel Plated (http://www.summitracing.com/parts/aer-fbe4024)
D. On the Oil Filter Adapter remove the 12 AN Flare fittings Trick to Remove the 12 AN Flare Fittings (http://www.zr1.net/forum/showthread.php?p=240416) and use two 10AN Flare to 3/4 inch NPT (http://www.summitracing.com/parts/aer-fbm2531)
E. Oil Cooler Adapter
With the secondchance design use one "O" ring on each 10 AN Flare fitting with 18x1.5 metric thread.
With the Jeffvette design use one Stat-O-Seal, 5/8 in Inside Diameter, Aluminum with O-Ring (http://www.summitracing.com/parts/ear-178010erl)on each 10 AN to 3/8" BSPP Straight Adapter.
F. One 6mm x 1.0 x 35 mm SS Allen head bolt (http://www.summitracing.com/parts/gar-73742/overview/)
G. One 6 mm SS washer (http://www.summitracing.com/parts/arp-200-8414/overview/)
H. Two "O" rings for the Aluminum adapter manifold to oil cooler interface.
The first seven items can be found at Summit Racing (http://www.summitracing.com/).

I have never had one of these hydraulic lines with Aeroquip Reusable Fittings leak and they are much much tougher than original crimped fittings and easily replaced or adjusted if you want to at some point make them longer or shorter (the fittings are reusable and swivel). And......you will find a much better routing of the lines if you make them yourself by looking at the routing of the existing Hydraulic Lines. The Aeroquip Reusable Fittings come in all sizes and angles to fit any situation. You can make your own oil cooler lines as shown here and Power Steering Lines or any other hydraulic line you might need on the ZR-1.
As an aside, I use the similar Aeroquip reusable fittings and Aeroquip 1509 hydraulic hose on all my farm implements and tractors. I make up all my implement hydraulic lines often replacing relatively new lines that come with the implements with my own lines that are much more dependable under extreme usage. We are talking hydraulic pressures over 2,000 psi on the hydraulics of some of these implements when the cylinders reach the stops.
Once you experiment with making your own hydraulic lines with some using SS Braided hose you will never look back at buying ready made hydraulic lines again. All you need is a vice, hand grinder (or even a hack saw will work), and a couple box wrenches of appropriate size. Oh...and an air compressor to blow clean the lines after assembly.

New Secondary Port Throttle Vacuum System for 1990-1995.
See.......Post 234 - Installation of New Secondary Port Vacuum System hoses (https://www.corvetteforum.com/forums/c4-zr-1-discussion/3005470-tech-info-lt5-modifications-rebuild-tricks-500-hp-12.html#post1590759176)
This complete NEW vacuum system designed for the 93'-95' can be installed on a 1990-1995 ZR-1. For 1990-1992 this can be accomplished by substituting the longer Manifold Differential Pressure vacuum line on the original 1990-1992 ZR-1 Vacuum System for the shorter curled MDP Vacuum line in the New 93'-95' Secondary Port Throttle Vacuum System.
The New vacuum system connectors are New soft rubber and easy to disconnect connectors which are very tight (just twist the plastic tube back and forth and they will let loose). The Original hard rubber connectors are impossible to disconnect without cutting the connector lengthwise (with razor blade) to remove the plastic tube.

The Tee (T) was moved and a 1 inch long 1/8" Fuel Line PCV/EEC (SAE 30R7 obtained at O'Reillys) was used as a splice where the T was located.
The Stock MDP Vacuum Line was used and added to the New Secondary Vacuum System. I replaced the stock L fitting with the New L fitting removed when T was re-installed for the Drivers Side Secondary Canister.
In this case I also used the Stock line with New L fitting from the check valve to the Vacuum Pump line as that Stock line was just a bit longer

I see no issues for long term use as I have now tested three IFPR (2-1990 and 1-1995) with over 300 operating miles. It will now be so easy to change out Delphi FPR removing failed Delphi (may never fail once installed) or change out the Dephi (for higher pressure or lower pressure Dephi) from the Modified Stock FPR Housing which take only a couple minutes (release fuel pressure in Fuel Rails first). I have installed one Prototype IFPR and two Production IFPR with the same results.....NO LEAKS and PERFECT Performance under ALL Driving Conditions.
The Delphi FP10016 is NOT modified in this Application......there are five items that come with the Delphi FP10016 (Plastic Adapter, Screen and snap ring with two additional sliders) that Phil does NOT use.
Phil has eliminated the plastic ring, the screen and the snap ring and is using the "O" rings.

Pulling the Plenum for most is a BIG deal and most often the Plenum is Pulled to fix a No Start Situation, an Alternator or to replace Injectors. I would say if you recondition your Starter and/or install a reconditioned Alternator or New Injectors...
then also install the Improved Fuel Pressure Regulator at the same time :thumbsup:

The Oil Filter Adapter has many important functions. The Oil Filter Adapter is NOT for the sole purpose of holding/adapting the Oil Filter.
The oil paths through the Oil Filter Adapter Housing are describe in Item #5 below.
1. A Discussion of the Functions of the Oil Filter Adapter.
a. Control Oil Temperature. See Related ECM Code #52 Item #3 ZR1 ECM CODES 1990 TO 1992 (http://forums.corvetteforum.com/c4-zr-1-discussion/3005470-tech-info-lt5-modifications-rebuild-tricks-500-hp-3.html#post1581564102)
b. Provide Sensor Feedback to the Instrument Panel.
c. Provide Oil Filtration.
d. Assure proper Oil Flow at any Oil Temperature.
e. Assure proper Oil Flow with contaminated Oil Filters.
The Oil Pressure Regulating Valve situated between the Oil Pump and Oil Filter Adapter controls and maintains Consistent Oil Pressure.
As an aside
2. Oil Pressure Sensor (Dash Gauge) Malfunction I changed out the oil pressure sensor for the dash gauge (top of oil filter) after engine installation. Oil pressure cold was registering 75 lbs. After changing out the oil pressure sensor, oil pressure is registering 55 lbs steady hot or cold and does not increase much with revs.

3. LT5 Oil Pressure and Oil Temperature Regulation
a. The Oil Pressure Regulation Valve (OPRV) (just after oil pump) opening pressure is 50-60 psi.
https://cimg0.ibsrv.net/gimg/www.corvetteforum.com-vbulletin/350x300-1/80-84b14ee2_b643_4c69_a2a9_de0d92b58a67_1__d0b45ac6f2 fc982e25265f692aaf0327c95368f6.jpghttps://cimg2.ibsrv.net/gimg/www.corvetteforum.com-vbulletin/350x300-1/80-b240ad00_2193_4ba2_add1_45ef52b8423d_1__48636a07ef f2ddd9e449504708d43b5879d8e082.jpg
b. The Oil Cooler Bypass Valve on the Oil Filter Adapter allows oil to bypass the open oil cooler at hot temperatures since oil cooler is a bit restrictive. This valve raises the pressure a bit on the flow trying to bypass the oil cooler making sure some oil does go through the oil cooler.
c. The Oil Temperature Control Valve on oil filter housing opens oil flow from the oil cooler. The temperature opening characteristics of this valve are Thermostat-Open-203 degree F, Fully open-266 degree F.
d. The Oil Filter Bypass Valve on oil filter housing allows oil to bypass oil filter if the oil filter becomes to restrictive.
e. Oil pressure is always available to the Oil Cooler Bypass Valve. Oil flows from the oil pump (past the OPRV) to the oil filter through the Oil cooler and through the Oil Cooler Bypass Valve or directly through the Oil Temperature Control valve when the oil temperature is below 203 deg F. The oil cooler flow return and Oil Cooler Bypass Valve are open at the same time. The oil flow from the oil cooler is never totally blocked (half moon cutout of shuttle valve). The Oil pump flow at Idle is 1.6 gpm and the Oil pump flow at 7,000 rpm is 9.1 gpm.

5. Oil Flow Paths.
COLD - Oil Temperature Less than 203 deg F.
a. The Oil is pushed up from the bottom Port on the Oil Filter Adapter Housing past the TOP Oil Cooler Port which is ALWAYS OPEN.
b. The Oil then is pushed through the Top Opening of the Oil Temperature Control Valve to the bottom of the Temperature Control Valve Port.
c. The Oil is also pushed against the Oil Cooler Bypass Valve which it will not open since the path through the Temperature Control Valve Port is Open.
d. Some Oil flows through the Oil Cooler back into the Bottom Oil Cooler Port since the Bottom of the Temperature Control Valve has a Half Moon Port that is Always Open.
e. The Oil then pushed up through the Oil Filter Outside Diameter and also against the Oil FIlter Bypass Valve just in case the Oil Filter is too Restrictive.
d. The Oil is then pushed out the center Oil Filter Adapter Fitting (M20x1.5) past the Oil Pressure Sensor for Dash Gauge, past the Oil Temperature Sensor, and past the Oil Pressure Switch Light on Dash Sensor out the Top of the Bottom Ports of the Oil Filter Housing Adapter to the Crankshaft and Top End Camshafts. The Oil pressurizes and lubricates the Timing Chain Tensioners and Timing Chains as the oil flows.

6. There IS an Oil Level Sensor on the 91'-95' ZR-1 Oil Pan.
The Oil Pan for 1990, 91 & 92 are interchangable with the only difference being, the 1990 LT5 engine was not equipped with a Low Oil Level Sensor. The extra material was cast into the pan but not machined for the screw-in sensor. As such, the oil level indicator would not be functional if the 1990 oil pan is used for 1991 & 1992 applications Oil Level Sensor TIPS (http://www.zr1.net/forum/showthread.php?p=182299)

1. This photos were resized on my computer using PAINT.
2. Then the photos were uploaded to my Registry Albums on this Forum.
3. I then clicked on one photo and copied the BB Code which is posted as [IM G]http://www.zr1.net/forum/picture.php?albumid=211&pictureid=3063[/IMG]
4. I left a space between the M and G so the photo would not show ;)
Just showing what you can do with Album Photos using Paint on your computer before you upload to your Albums on this Forum.

33 Data Clock Circuit-Circuit shorted to battery voltage or CCM driver open
35 Data Strobe Circuit-Circuit shorted to battery voltage or CCM driver open
37 M Clock Circuit-Circuit shorted to battery voltage or CCM driver open
72 LCD Dimming Open Circuit-Circuit open or shorted to ground (radio & Climate control)
H History code. May be intermittant.
Code 31, 33, 35 related to the circuit from the CCM to the Instrument panel LCD.
CCM 74 is also a lighting circuit problem.
CCM 41 is loss of communication with the ECM.
3. ZR1 ABS Code - Definition
1990 Service Manual:
(* = Requires Tech 1 Daignostic Tool)
12 - Diagnostic System Operational
21 - RF Wheel Speed Sensor Fault
22 - RF Toothed Wheel Frequency Error
25 - LF Wheel Speed Sensor Fault
26 - LF Toothed Wheel Frequency Error
31 - RR Wheel Speed Sensor Fault
32 - RR Toothed Wheel Frequency Error
35 - LR Wheel Speed Sensor Fault
36 - LR Toothed Wheel Frequency Error
41* - RF Solenoid Valve Fault
45* - LF Solenoid Valve Fault
55* - Rear Solenoid Valve Fault
61* - Pump Motor or Motor Relay Fault
63* - Solenoid Valve Relay Fault
71 - EBCM Fault
72 - Serial Data Link Fault
75 - Lateral Accelerometer Fault (Short to B+ or Ground, or Open Circuit)
76 - Lateral Accelerometer Fault (Signal Out of Range or Incorrect)
Clearing Codes
The fault codes in the EBCM's memory are erased in one of three ways:
1. Diagnostic Enable Line Procedure
2. Tech 1 "Clear Codes" Selection
3. Igniton Cycle Default
Whichever method is used, be sure to verify proper system operation and absence of codes when clearing procedure is completed.
4. ZR1 Ride Control (SRC) Codes.
12 = Start of sequence
13 = Left rear time out
14 = Right Front time out
21 = Left Front time out
22 = Right Rear time out
31 = Left Front out of position
32 = Right Front out of position
33 = Left Rear out of position
34 = Right Rear out of position
Out of position codes are triggered if the computer senses that the actuator has not found the end stop position on the shock. Remove actuator at the indicated shock. Turn the valve gear on the shock stops after about 3 / 4 of turn, then you have a bad actuator. If it spins around continuously then it is a bad shock
41 = Selective ride control switch short to voltage
42 = Selective ride control switch open contacts
You can have a code 42 if you leave the switch in between indented positions
43 = selective ride control switch circuit open.
23 = If you start the car more than 3 times and do not move the car this code will set. Drive 3-6 feet and the light will go out.
The ride control controller is located in the bin behind the drivers seat mounted with the ABS controller.
