turbo proof gasket??

[Slayer]

got a leak around the waste gate, its loud and anoying. the 2 parts dont have a gasket between them and i have tried everything. gasket goo, mufler putty, u kneed it.. they all just cant take the heat and end up turing to blob of smoking charcole.. can no longer buy gaskets the shape i need, but id love to cut my own, just dont know what it needs to be made out of so it can take the heat.. or is their a putty of some sort i havnt tried that will handle it??
thanks in advance for sugestions??

there is stuff available, lots of my mates are into the turbo rotary thing and cut their own gaskets.
i'l find out next time i talk to a few of them.
you could try an aftermarket turbo fitting workshop
also try fullboost.com

u don't need a gasket. run a straight edge over both parts where they bolt together, and see if they are warped.both surfaces need to be clean and straight. get it machined if its warped . a gasket may help, but usally not for long. good luck!

I agree. if you need a gasket there, something is warped, and even with a gasket that can take the heat, it will blow out sooner or later. is your truck petrol or diesel? if diesel the exhaust temperature at the wastegate should never exceed about 600 - 700C which the copper colored high temp silicone sealants can handle occasionally - your normal exhaust temp at that spot should be around 200 - 300C at cruise and lower at idle.

so you might have 2 problems - too high exhaust temps and warped turbo bits (which might have been caused by too high EGT)
