Hi Guys,

Well - I survived replacing the PCV Oil Trap / Breather Box system - new hoses and all. Now I have a damaged #4 Cylinder Exhaust Manifold Gasket. Probably due to a leaking Camshaft Oil seal, recently replaced with no new oil leaks.

I would be grateful for tips on not screwing up re:
** Breaking studs, seized nuts - what to spray on them to loosen ??
** How to get the exhaust manifold off - been told I may have to pry it off and don't want to damage the ?block?
** Can I just loosen the nuts and pull it back enough to put on the new gaskets - or do I have to remove other parts like the ? turbo drain tubes?

You can tell I am a newbie, but I did the above two jobs so I have a little experience.

Many thanks in advance for your help.

Tom

 

PB Blaster rusty bolts and let them it soak in overnight if possible. I would not worry about damaging the block - once all the stud nuts are off there shouldn't be anything keeping it stuck to the block as the gasket is dry. The manifold needs to come off as the gasket has bolt holes for the studs. Keep in mind that the turbo bolts to the manifold so you need to remove that as well (including oil and water lines). Check YouTube for vids on removing turbos. I'd pull the manifold off and inspect for cracks, broken studs (which can be unscrewed from the block).
