Re: TB removal and then some!!!
Preliminary test fit.....so far so good...
you can really notice the contrast in color between the plenum and cam covers, but that is for another time... http://i127.photobucket.com/albums/p...2_155344_1.jpg http://i127.photobucket.com/albums/p...702_155805.jpg |

Re: TB removal and then some!!!
If you are talking about coolant elbow attached to the plenum, you can grab it lightly with adjustable wrench and twist it back and forth until it pulls off. Hole can be plugged with metal press on cap. I think it was 3/8" cap. Check the hole diameter. May have been 1/4".

Was ready to install the 12pt SS bolts to the plenum, but wanted to verify using washers with the bolts. That was confirmed, but need SS washers, I ordered no SS. So just ordered the washers I needed, so the install get delayed. On another note, the 10mm long socket works perfect with a long extension for in between the runners and all of them for that matter. Also a pencil magnet is a huge plus when installing or removing some of these bolts. Makes life easier.....lol wrong washers, but they look nice....lol http://i127.photobucket.com/albums/p...703_194842.jpg checkout front bolt...and the 10mm socket and extension... http://i127.photobucket.com/albums/p...703_195005.jpg pencil magnet for install & removal...a breeze... http://i127.photobucket.com/albums/p...703_195044.jpg |
Re: TB removal and then some!!!
If the pencil magnet works on the SS bolts, maybe not SS?

ARP m6-1.00 12PT STAINLESS STEEL FLANGE BOLT (size may vary) the description also states that they are 300 stainless steel which I don't have a clue to what the 300 means.... I do not know the correct answer to that, so I did a google. this is what I found... Will a magnet stick to stainless? "Due to this difference, ferritic stainless steels are generally magnetic, while austenitic stainless steels usually are not. A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure." I would imagine then that these bolts are ferritic SS. Looks like we both found the same answer.....lol |
Re: TB removal and then some!!!
Ferritic stainless steel will rust!

The simple solution to all of the rusting issues on either style bolt, is to change them when they do!!!:):):) Then again from the above quote.... "ferritic stainless steels are generally magnetic, while austenitic stainless steels usually are not" the words "usually are not" can also be interpreted that these bolts can also be austenitic stainless, which could mean that some are and some aren't......hmmmm the mystery continues..... |
Re: TB removal and then some!!!
They can rust but not as quickly as mild steel with chrome heads.
We have used them on water features and they rust; the treated water is more corrosive than any water/moisture you have or use on your engine. |
Re: TB removal and then some!!!
Tom,
Unless you plan on doing a lot beach driving with an occasional dip in the surf you should be ok with these bolts being more or less rust free. |
Re: TB removal and then some!!!
John, I think I'll be fine with either one, I'm sure I'll be long gone before a change is needed...
I don't know Phil, was planning some beach drives at the Jersey Shore, guess I'll be rethinking that.....lol Sent from my SM-G935P using ZR-1 Net Registry mobile app |

Re: TB removal and then some!!!
Plenum is now torqued down and secure @ 19 in-lb. Although it has been said, IIRC that when blocking the coolant from the plenum and TB, it is not necessary to torque the plenum bolts to spec. I did torque to spec or close to it, as my 1/4" drive TW starts at 20 in-lb. So I just torqued by feel as evenly as possible and did not get the click for the 20 in-lb setting.
I coated all of the bolts for easy removal in the future. I used Perfect Seal and an artist brush to apply a very thin coat. All went well... I did run into a problem with bolt #12 which is located at the rear of the plenum on the passenger side above #8 cylinder. I found out that the fuel line was in the way not allowing the 12pt or the SS bolt (from Jerrys) to be inserted. I then loosen the fuel line so I could get better access and of course some fuel squirted out (I am sure because of being under pressure) for a second or two. I was then able to install the 12pt bolt with no problem. Tighten up the fuel line and I was then able to get my socket in there for torqueing down the bolt. The flat SS washers came in on Friday, I ordered "thin" 5/16" & 1/4" SS washers and they worked out just fine. They were less expensive than ordering a new set of the SS Metric versions. The non-SS metric (zinc) ones that I had ordered from before are really wider as you will see in the pics. Thanks to Jep for his suggestions and recommendations for the bolts, washers and much more....appreciated.....:) metric washer on the top, SAE washer on the bottom...appears to be same inside diameter, but you can see the difference in the overall diameter... http://i127.photobucket.com/albums/p...709_185541.jpg plenum bolt with metric washer, you can see how it extends outside the 12pt bolt... http://i127.photobucket.com/albums/p...709_185413.jpg plenum bolt with 5/16" SS washer...you can see how it is flush with the 12pt bolt with no extension outside the bolt... http://i127.photobucket.com/albums/p...709_185655.jpg how to set the washer between the runners that are tight....used the pencil magnet to hold the washer in place and a sprayer extension tube to press down on the washer and release the magnet when in place, worked great... http://i127.photobucket.com/albums/p...709_190314.jpg inserting the bolt(s) with the pencil magnet....no problem... http://i127.photobucket.com/albums/p...709_192039.jpg http://i127.photobucket.com/albums/p...709_192058.jpg |
Re: TB removal and then some!!!
thin coat of Perfect Seal applied to the bolt...overkill....maybe, but it is done...
http://i127.photobucket.com/albums/p...709_191549.jpg 10mm deep socked works great to tighten down those hard to reach bolts as well as all of the bolts...no need to use your fingers anymore trying to put the bolts in place.... http://i127.photobucket.com/albums/p...709_192154.jpg #12 bolt, looking at it from this angle, you may say it looks like no problem getting in there.....not....unless I missed something about installing the bolts at one time or another, the fuel line does present a slight install problem... http://i127.photobucket.com/albums/p...709_200754.jpg now from this angle, you can see what I mean about installing the bolt and the fuel line in the way....once installed the 10mm socket fits perfect to tighten with no interference at all... http://i127.photobucket.com/albums/p...9_200801_1.jpg RS....done... http://i127.photobucket.com/albums/p...709_200749.jpg LS....done... http://i127.photobucket.com/albums/p...709_200637.jpg |

Trying my experiment on the TB with the Dry Moly Lube instead of the dag. Not having the success and results I was looking for, I decided to give this a try. After applying several coats, there is still some day light around the blades. I am going to try to brush it on those areas and see what happens. I may also use the dag in addition to the moly lube just on the bore surface in the blade area and again see what happens...
Taped up the bore area so the lube wouldn't be sprayed all over. This may be a longshot and not work as planned. But you'll never know unless you try it.... experimentation at its finest..lol We shall see....

Tom,
You missed another cruise! Mystic ZR-1 and I saved you a parking spot. :cheers: |
Re: TB removal and then some!!!
John,
Looks like it was a good turnout...you really saved that spot for more sitting space..lol Ok have to test my memory, is the roadster in front of your vehicles a Morgan, or ??? That looks like it is in great shape. And also quite a variety of cars... BTW, needed sunglasses to view, as the reflection off the Z was too much for me to handle..lol Sent from my SM-G935P using ZR-1 Net Registry mobile app |

Re: TB removal and then some!!!
Been busy lately with the 74, haven't done much with the 94 until today. Also slight back complications slowed me down some and recently started a new FB page for the 454 during the early to mid 70's. May also be including 396/402's and 427's from previous years, as we now have some of those owners who have joined the Group.
So when you mess up, you mess up and I messed up....went to remove the elbow from the front of the plenum and it did not go well.....chipped some of the paint on the plenum in the process and the elbow broke off. So part of the rim is still attached to the plenum......oh well!!!! Did a touchup and have to figure out how to plug that hole, so far the caps don't want stay in there......so have to give this some thought so I don't mess anything else up....lol new size caps came in...3/8" http://i127.photobucket.com/albums/p...725_114205.jpg not too much of a difference between the 3/8" and the 1/4" that I can tell... http://i127.photobucket.com/albums/p...725_115207.jpg http://i127.photobucket.com/albums/p...725_115246.jpg the dreaded busted up elbow extension...I would have been better off leaving it in place.....lol http://i127.photobucket.com/albums/p...725_123107.jpg when you mess up, you mess up..... http://i127.photobucket.com/albums/p...725_123116.jpg |
Re: TB removal and then some!!!
I am not too sure how good this paint will hold up in the future.....so there may be another plenum pull next year....lol
Don't know if I should take a chance and try to get the rest of the "tube" out of the plenum.....hmmmmm.... the mess up... http://i127.photobucket.com/albums/p...725_123133.jpg the touch up....not NCRS....but good enough..... http://i127.photobucket.com/albums/p...725_130137.jpg also gave me the opportunity to go over some of the pipes.... http://i127.photobucket.com/albums/p...725_130157.jpg |
Re: TB removal and then some!!!
Your paint job looks great Tom. Get that ZR-1 back together and bring it to WAZOO WMD. We can get the tube remnants out.

Re: TB removal and then some!!!
As you know I have working on and off on the TB, well today I wanted to see if my idea with the dry moly lube worked out better than using the dag. Answer, not really. So I can still see daylight through the secondary blades, but I now have sort of a "dag" foundation on the blades and in the bore. No one to give up (just a glutton for punishment, lol) I will order another container of dag and this time apply it better than before learning from my previous application.
So the process continues...... inside the bores, still taped up... http://i127.photobucket.com/albums/p...727_184229.jpg tape removed and you can see the line of the dry moly lube in the bore... http://i127.photobucket.com/albums/p...727_191044.jpg and on the blades... http://i127.photobucket.com/albums/p...727_191100.jpg daylight....not good..... http://i127.photobucket.com/albums/p...727_191303.jpg ugh.....lol http://i127.photobucket.com/albums/p...727_191309.jpg http://i127.photobucket.com/albums/p...727_191343.jpg http://i127.photobucket.com/albums/p...727_191358.jpg |
