High Temp Rtv For Exhaust Gasket

[ifixedit]

I recently replaced my turbo gasket with a thick type, maybe thats my issue but Its leaking again and I spotted the area the exhaust gasses are leaking from it's 100% the gasket

again

I remember having troubles with my turbo gasket on an old s13 while living in thailand

in the end we used some type of thick gasket maker stuff on both sides of the gasket and worked like a charm. even 1 bolt came loose and didn't effect the gasket..

my current skyline is having problems and think its simply just a shitty gasket. I will buy another gasket and try again. (turbo->manifold) I am going to buy the thin stainless type this time

I am seeing RTV COPPER gasket maker.. Im sure that was not it..

the stuff I used I am sure was basically creamy ceramic or something and when dry it was crumbly i.e. ceramic

anyone know what I am talking about? or would you recommend the copper..

The copper is good for around 350 Degree C, im sure ceramic would be better!

Use a genuine Nissan metal gasket only. If you still have problems then the flanges may be warped. Worth checking when you have it apart. Rtv sealant won't last long in that type of heat.

The stuff you are describing sounds like exhaust cement. I wouldn't use it. Its a dodgey way to fix your problem and won't last long.

Thanks for the reply.

I will do just that.

I would rather not spend $50 for a OEM gasket..

Would this Permaseal branded Gasket be as good?

Look at this on eBay http://www.ebay.com.au/itm/282010176771

Worth the extra 10. Will last a lot longer. Do it once, do it properly.

Back a while it was impossible to source the dump to turbo gasket for the HKS2835 ProS.

I tried that RTV Copper gasket maker, worker a charm, no problems.

Still use it on my farm machinery exhaust manifolds, never had a leak.

Good to know that stuff works

Didn't have a choice with the ProS and that stuff is good for way better than 350 deg C.

Turbo was almost see through on the dyno, well over 500 deg C. (which is usually cherry red)

Any silicone on the turbo gaskets will turn to powder in no time.

The permaseal T3 gaskets are OEM quality, never had an issue with them.

what I do is clean both surfaces, make sure all the studs are good, use new nuts, and a oem gaskets and a light amount copper gasket maker never had an issue with leaks.

beautiful,

Ordered an OEM gasket thanks to a ebay referal here

I got some new tube of copper stuff hehe permatex

Ill do it one weekend... and will ensure to tighten properly...

any comments of how best to tighten those bolts that are in an asshole corner.. the bottom ones! leverage and angle is odd to get a good grip

[jiffo]

Read the blurb on the copper gasket maker to ensure it's oxygen sensor safe.

Used to use a VHT copper spray on head gaskets always worked, but [although the specs were good enough] never needed to use it on a turbo flange gasket.
