i ve got the engine on the bench so iam gona do a few jobs. valve clearance seams outa whack so iam gona look at that. any engine i re shimed in the past involved removing the cam i think on this engine its doable with the cam in. if ive got a load of shims to change it might be just as easy to take the cam out? maybe i should take the head off and grind the valves? then i would probably do valve seals and skim the head Where do i stop? rings? spose a compression test would tel me that. iam gona put a new flywheel end seal in also. maybe take the sump off for cleaning and inspection. the engine was oily when it came out of the car but there was no clues as to where the leaks were oil and dirt was evenly distributed every where, maybe that points to the cam cover gasket?
