THIS is why you dont use RTV

I agree, but before Z1 had theirs out, RTV was a good second choice

Aren't the directions put in on, tighten only a little, wait a few hours, then tighten to spec. After 24hrs its gtg. I can't see a shop doing this!

That's what I've seen on the back of every tube I've ever bought. Every time I followed directions it worked flawlessly. The only time RTV didn't work for me was when I was using it to redneck-engineer something and it was the wrong tool for the job.

Depends on the quality of the shop......

even the best silicone is only good up to 500F so it will fail eventualy on manifolds and cats that can reach temps well above that.

Doesn't matter. No ones gonna pay 3 hours additional labor for a TP job.

RTV copper is 700*. It never failed me on a 1600* turbo, but I use a gasket with RTV on both sides.

My high temp copper rtv gaskets are working, but I wouldn't mind adding those z1 gaskets to my wishlist

Thx for the idea

Didn't you buy used? Looks like someone modded your car before haha. Looks like a crush gasket to me on that. But what do you think 9 and 18 are?

Yeah, that pic shows a metal gasket squished around the pipe.

OK so there is a metal crush gasket that only fits on the cat. There isn't anything like the pic you posted on there. I bought my car used but it was bone stock down to the air filter.

lol doubtful, but ill bite

i can say safely nothing to the exhaust side was messed with, not too sure about the intake side although it was a pita to get off when i had my short rams installed there

synolimit · 12-18-2013, 02:24 PM

Here's the 09 PDF, same as the 13 pic above, gasket at every location.

Joepro · 12-18-2013, 05:03 PM

I have been using the COPPER as others have said the COPPER RTV for years. Both mating surfaces must be clean, real clean. Place a good sized bead on the TP flange, then tighten it up, but not torqued down. I let it sit for an hour, then torque it down, done. NO leaks long after gaskets start leaking. 8 bucks at advance for a tube enough to do a whole exhaust.

wstar · 12-19-2013, 04:35 AM

I used the metal gaskets and put a thin coat of the copper stuff on both sides of the gasket before installation. Helps it stick in place when lining up the bolt holes anyways, and hasn't leaked
