My brothers turbo cobra needs a new bolt and has lost its seal at the t4 flange that meets the headers. What is the BEST liquid gasket to use there? Or better yet t4 gasket? Thanks

i usually used a small bead of Copper impregnated silicone for, its orange at any auto parts store, in conjunction with a new t4 steel gasket.

not a prob man, tell him not use a huge amount, just a nice bead around the flange, allow it ample time to set up, he wouldnt want a goop of that stuff going through his turbine. EEK, lol

On this topic. I was just told to only use a bead of High Temp copper silicone. That is what I used but NOT with any gasket. I used about a 1/4 bead and when I tightened it down it smashed out pretty good. Should I have used a T4 steel gasket? Shoot didn't know they even made them...

I don't use turbo flange gaskets, just some copper rtv

Always used the multilayer steel gaskets with a little copper spray.

I've had excellent luck with a MLS gasket and nothing else.

Im just using the supplied gasket.. why is everyone one switching to the RTV? I know its good stuff but is the steel one that bad?

If the flanges are flat, then no gasket or sealant is needed.

And if the flanges are not flat, make them flat !
