Waiting with bated (baited?) breath - no leak yet today.

Composition gaskets don't creep - only cork and I wont use them on trans pans. 12-16#ft torque (180 in lbs is what I used with my small torque wrench) which is correct for a Gr8 5/16 bolt.

If it still leaks, it looks like there are a lot of good suggestions on how to fix it .

Dave

Looking carefully you see it swell out as you tighten, that is what I was referring to.

I just said @#$% it and ordered a Trick Flow cast aluminum pan from Summit a few minutes ago . The TCI pan started oozing at the left rear again. I removed it and checked it out. It's flat side to side, the bolt holes had started to distort a bit, but within normal limits and easily fixed with a ball pein hammer - but the chief culprit is that the Chinese dies didn't make a totally flat sealing surface - there is an area about 1.5 inches across the back that is rounded, not making a fully flat surface to seal and, guessing now, that when I pulled it tight, it warped a bit, just enough to leak. I miced the steel just for snickers - it's .035 vs. the OEM of .051. That's 16 ga for the OEM pan and 19 ga to the POS TCI pan - 3 gauge sizes thinner.

This has been an interesting lesson in frustration - the cheapie import stuff in many (most?) cases, is a waste of time and money. You buy what you think is a good brand name and it turns into more Chinese junk . I only can hope that the TFS pan is a good component now or another $98 is frittered away.

Guy - thanks for all the helpful suggestions. I guess I shoulda known that Chinese junk is .....junk.

Most likely should but I've had it a long while (over 3 years) and probably can't find my receipt from Summit or Jegs

Ireland,
so all will know....
the reason I posted "it is distorting under tension" way back on this thread is based on: "been there done that" with a TCI pan a long time ago....a used plus a new cork gasket did fix it

"ouch"....$100 to "fix a leak' is "plumbers pay"!

This was more than distortion - the @#$% thing had a rolled area of flange instead of being flat. Double gaskets and silicone would have most likely fixed it - or I could have used my OEM pan. Once I finally made my decision to change it out, the aluminum pan just caught my fancy, especially since there is significant chrome, aluminum and stainless on the rest of the chassis and engine. See the attached.

I'd like to suggest a length of hi-temp insulation tubing on the gas line where it passes by the exhaust manifold....stuck in traffic you will be boilin' the @#^& out of the gas.....

just for laughs, here's a pic of my current C-4 pan.....dang my car seems lower every time I try to see something underneath...or take a pic'

Thanks - my 'last' baby
There is an aluminum heat deflector that gets installed with the fender - and I do intend on running sans hood sides most of the time so it wont be quite as hot.

It looks like you have some aluminum extrusions attached to the pan - how? Epoxy?

Originally I had a 2-3 quart additional aluminum pan - it was only about 2.5" from self destruction against the first road crown. so it got sold. The TCI was the back up, and obviously didn't work out.

Thanks - Now if I could only get a break in the weather(it's 7deg F, 25-30mph wind) so I can paint the body, I wouldn't have to look at that nekkid chassis any more.

I have been thru this very same game with my C4. All the different pans and gaskets, still leaked. No matter where I looked I could not find any other indication than the pan. Then I mentioned it to an old time mechanic friend. He asked if I was sure that it was not the filler tube gasket instead of the pan. Oh I was sure it was the pan, untill I looked real good at the area between the case and the filler tube. There it was, running down onto the pan. All that time and money for a little oring.

I'd explain it to them, and let them know this thread address. They NEED the good will that $20 will buy them.
