So, I did the seafoam treatment recently and found I had a little white seafoam smoke coming into the engine bay. So I went an replaced the uppipe and downpipe gaskets with fresh OEM ones. I did the Seafoam treatment again yesterday and still have a little seafoam smoke coming up in the engine bay.

What should be my next plan of attack? I know my uppipe isn't cracked. I also know my turbo inlet has a good tear, but I don't see how white smoke could be coming from the inlet. Should I start replacing header gaskets and whatnot?

+1 the cross over is a flex section so could be that too

Mine was junk

So I have another question. Say I just pull out my crosspipe and put new gaskets in, I know from Grimmspeed's instructions you are to loosen the passenger side exhaust collector to the uppipe bolts. Should I replace the new uppipe gasket I just put in there, since the ring on the inner diameter of the gasket is now crushed?
