Re: TB removal and then some!!!
 

As you can see in the above pics... 2 of the wheels look good...finally figured out what seems to work best for me in removing those stains....or as much as I could remove.... green Scotch Brites and Blue Magic cream polish....in conjunction with everything else on top of the tire....[emoji16][emoji16]

Re: TB removal and then some!!!
 

Ever since I've owned my 94...there has always been slow air leaks in both rear tires...so today loaded up the tires in the Vibe and took a ride to NTB...
The RR tire ended up with a nail that has been in there forever...
They couldn't find a leak in the LR tire...but since I was there had both tires removed (RR) to be repaired and LR to be cleaned....
No signs of any dry rot outside or inside of both tires....which are from 2012....they both look great....so good news there....and the tire sensor just fell off the RR inside wheel....so no biggie there....recleaned the wheels and tires with Stoner tire dressing and Speedy....not pristine or show wheels...but decent for a driver...
Still have more to do to get back on the road....but progress being made....[emoji16][emoji16]

Pic #1....the nail that has been with me for the last 6 plus years...
Pic #2....recleaned all of the wheels with Stoner tire dressing and Speedy....
Pic #3...3 done and looking decent...not pristine or show quality...but good for a driver...
Pic #4....may get these refinished some day and use my spare set when these get redone....
Pic #5....the tire sensor just fell off the inside of the wheel...may have happen during the removal....Attachment 13111Attachment 13112Attachment 13113Attachment 13114Attachment 13115

Re: TB removal and then some!!!
 

Two thoughts: First, I had a slow leak in a rear ZR-1 tire that a good tire shop could not find. Took it back to Costco where I had bought the Michelin tires and they immediately said "leaky valve". They replaced the valve without charge and the slow leak stopped. As a side note, I usually pumped up my tires to about 50-55 psi for winter storage to avoid flat spots. They said the valves are only warranted for 40 psi. Second, that nail looks like it is a recent addition. Usually a nail that has been in a tire for a short while will wear down flush and be quite shiny. That one doesn't look worn. Maybe a bad valve in that one too, along with the nail?--Bob

Re: TB removal and then some!!!
 

Thanks Bob....both tires are holding air just fine....I run 30 lbs pressure in them....finally getting the work done that needs to be done....lol can't wait to get back on the road....[emoji16][emoji16]

Getting more done on the 94....going to clean more of the suspension and install the Hawk brake pads....took the rotors off...I am assuming that these are the originals....if anyone recognizes the markings as originals...please let me know...
Dropped the front rotors off to get cut...
Was quoted $15 per rotor....but then when I got there...said $25 per rotor...didn't realize the price went up....but the service person honored what he said on the phone....so I lucked out there....will be done tomorrow...
Did a measurement around the rotor at each lug stud location....and in between...my measurements were between 26.55mm to 26.96mm thickness of the rotor...since I found a place to cut them....I did not measure the right side....hoping that they are within specs....[emoji16]

How did you find a place to machine the rotors?
No one around here will do it...

Re: TB removal and then some!!!
 

I goggled in my area to see if any shops offered that service....at first it mentioned Meineke....call them...they don't have the machine...called my local PepBoys...and they have the machine and provide the service....:):):thumbsup:

Re: TB removal and then some!!!
 

Good deal....the back ones will cost me $25 a piece.....I lucked out with the misquote on the front ones...total was $34 and change...so all of them cut will be about a total of about $90 or slightly less....still not a bad deal....as there are not many parts stores that cut rotors in my area....alot of them stopped offering this service years ago....:):)

Are you going to paint the front and back sides of the rotor hats? I always do that... prevents rust that looks ugly.. I even paint the "spine" of the rotors where the cooling fins are...:cheers:

Yes I intended to do that....might go with high temp black.... [emoji16][emoji16]

Re: TB removal and then some!!!
 

When I purchased my 94 back in 2014....one of the first changes I made...was to buy the chip from Marc Haibeck for the HP increase and fan operation...it was then that I discovered that the PROM in the car was different that what I thought would be there....different in the way of the markings on it...it has dates and Tim Holland's name allover it....
I then found out that Tim Holland was one of the Lotus Engineers responsible for setting up the PROM's for the LT5...this one being for the 93-95 versions...
Ended up tracking down Tim at that time and had a great conversation with him...as I also found out that my ZR-1 was a captured test fleet car and owned by GM for 2 years and 27,000 miles later...Tim started laughing and said..."that chip wasn't supposed to be left in the car, it was to be removed"...but he also mentioned that it was fine to be there...as that is the final version for the stock PROM's for 93-95...
He also mentioned that they drove these captured test fleet cars everyday just like a regular family car...went to the store, drove family members where they had to go...etc...etc...and IIRC when parts went bad if that happened....they were readily replaced....I am assuming that Tim might have used my car himself...since his PROM was in there...hopefully sometime in the future I will talk to him again...

Re: TB removal and then some!!!
 

Looking good... I also used silver. You really took some time on them with the tape... I wire wheeled them with my air die grinder and a steel wire wheel, balm canned them and wiped the braking surfaces down with some brake clean on a rag... =D>

Thanks....actually the tape didn't take that long.... I'm better off without the wire wheel on some items....lol

I think I could have potential electrical problems if I didn't discover these items...
1-positive battery connection...is there anyway to correct this other than replacing the positive battery cable...check out the pics....
2-also the wires to the rear fuse box (main wiring harness to the rear fuse box)... have or had corrosion (now removed)....but a break in one of the wires....which electrical tape should fix....
3-need to replace some conduit as it also is eaten away....
4-have no clue what I believe is a water drain from the windshield cowl area that dumps right into the battery area....where all this takes place....think I will somehow extend this....so it will dump out below the frame....
Just going to take longer than expected to get back on the road.... [emoji16] [emoji16]

Re: TB removal and then some!!!
 

You can get a replacement battery terminal connector. The issue with this is that the corrosion you see more than likely travels further up the cable, under the jacket. Maybe replace the connector, buy a new cable and replace it whenever you pull the plenum again.. The rest is easy fixes. Neutralize and clean up the corrosion, replace wire loom. The water is coming from the rubber drain tube from the windshield cowl area, re-route it away from the wires if you can.. :cheers:

Re: TB removal and then some!!!
 

What he said!

I would use a longer drain tube or a connector and an added piece to get it completely past that area.
That damage on the smaller wires also appears to be more battery acid induced than water drainage or accumulation causes.
That positive cable is trouble with a capital T!
Great that you went on your exploration!!!
:cheers:
Marty

Re: TB removal and then some!!!
 

Better off replacing all the suspect cables and move on. Replacing the positive starter cable will require pulling the plenum and coil tray.

Re: TB removal and then some!!!
 

Appreciate the replies everyone....looking for the correct positive battery cable.....in the meantime I found the battery cable washer that is used in the positive cables of our Z's.....it is part #11501869 and I assume that this is the size as it was posted with the part #......M8X15X.85 and that was used as mentioned for VIN J......did a search and nowhere to be found.... :)

Re: TB removal and then some!!!
 

So I did a partial cleanup on the washer and even went further inside the cover to remove any signs of battery acid powder in there....there was some...but the further I went...the less that there was....I ordered a battery cable spacer that I'm hoping will fit in there just right and provide full contact when the cable is attached....what i would like to do....is find that washer and cut the cover open and just replace the washer and then reseal the cover....as I never had any problems starting the engine at all....I really don't feel like doing another plenum pull if I don't have to...but if it has to be done....as I have enough going on as it is....lol....pics below after preliminary cleaning of the disintegrating washer so far...the metal that is still there is solid....so with the spacer added....it might work just fine....

I guess not.....but more than I expected behind the covers.....at least it will be corrected when I'm finished....still more to do....that is for sure....:)

Re: TB removal and then some!!!
 

Did some research and found that the battery cable washer is still available from GM....although a little pricey IMO....I ordered a couple of them from the dealer..I also found another set of cables for the LT5 from one of our members on the forum....so if my experiment doesn't work....I can always change out the positive cable....here is the part #11501869 for anyone interested....also found out that the part number for the positive battery cable is #12073841 (which we know is no longer available)...this part number was replaced by #15320758 as per the dealer parts man and is also no longer available....but may help in future searches for buying purposes....[emoji16]Attachment 13283

Re: TB removal and then some!!!
 

That washer looks like it or suitable replacement
would be available at any hardware store for a few cents?
What's so special about it?

Re: TB removal and then some!!!
 

Tom,
I have a new (NOS) 12106586 which I have listed as correct for 93-95 Corvette ZR-1
Maybe my listing is wrong, but the cable looks correct.
Let me know.
Thanks and Good Work!!!
Marty

Re: TB removal and then some!!!
 

Don't know Doug.....probably nothing special at all....but I committed already..:)

Thanks Marty.....just going from my info....your number may be correct and mine not correct...if you can send me a PM with a pic and your price for the cable.....and we can go from there......thanks again.
Tom :)

Re: TB removal and then some!!!
 

FYI...lesson learned.....the washer shown above part#11501869 is not for the battery cable end that attaches to the battery.....rather than it is for the "ring" ends that attach to the other connections.....which are much smaller....:confused:
