I have a leak in my wastegate, when i took it off there are black exhaust gases covering half of the flange. So i assume that it leaking at that place, is it possible to use silicone sealant for this or i should get a gasket?

 

uhh the wastegate gets pretty hot i wouldnt wanna use a silicone base product.

A gasket is the proper way to fix it..

Scroll to the very past thing on this page at very bottom

 

You can use red high temp silicone if you want to go that route and be fine. I would get a new gasket and use a very thin layer of red silicone on either side of it.

 

Yeah, i went out and brought some red hi-temp silicone gasket maker but has anyone used these on the wastegate flange and how did it work out?

 

those gaskets blow out too easy. Ive run no gasket and been better off since.

 

I am using only Copper RTV sealant(high temp gasket maker) on my WG and it works perfectly fine.. no leaks

 

i'm running high temp gasket maker on my waste gate and it works awsome no leaks

 

i'm running nothing inbetween mani/wg no leak for me
