I recently removed the Intake Manifold and Cross-over pipe to replace the manifold gasket (amongst other things). I had both parts hot-tanked and bead-blasted to remove all the crud inside so they were squeaky clean when reinstalled.
Problem is when I tightened up the flange on the Cross-over to manifold one of the Allen Screws would not seat properly and it looks like the thread is partially stripped. I used some gasket sealant but the joint is now leaking.
Short of removing the Intake (Again
) and fitting a Helicoil in the stripped thread, does anybody have any other ideas for a possible fix?
Would some type of Thread Locker work?
My other concern is that there is a little oil residue seeping from the flange. Does this indicate a Turbo Oil Seal problem?
(My EGR is removed and blanked off BTW). If so how easy is this to repair?
