all my gaskets are good its just that the bad head bolt i put in cause my head gasket to blow. Ive read to many post about upgraded turbos (which are rebuilds of the stocks with larger fins at least sports 500's) leaking oil right out of the box and stocks can boost up to 16psi with boost controller (pretty sure) so for my daily driver i need nothing more. On top of that if my turbo is just leaking at the seal the CHRA is all there is to a turbo anyway. The outside hosing is perfectly reusable once to didnt have contact between the fins and the hosing. At least thats how i feel.
