remove the head and intake manifold as 1.
The only bolts you should have to get are bolts on the back of the block for the intake manifold support.

oh and another thing that kinda plagued my dad and i...the head bolts, two of them were totally drenched with engine oil and the other 6 were perfectly clean except for the top. very odd.

i dont know about the bolts..

but valve seals

my valve seals went and it looked almost identical to that. had some oil in the intake but more so in the exhaust manifold.

what would happen is on cold startups my oil would leak through the seals... burn in the engine and get in the manifolds. then after the engine warmed up the seals would expand and no more leaking during driving.

wish i could help, i didnt do any compression tests. but from yours its obvious all pistons are experienceing the same effects. so that alone would make me guess its a fatigue type incident, not just a small blow-by in one cylinder

all i knew is that i was burning oil, and that it would stop after a min or so of driving. my friend hinted that my problem sounded like valve seals. so i ripped my head off, looked at the head gasket just to make sure, then took it to the shop and asked them to replace the seals...presto

if i were you i would replace the valve seals, you already have the head off the engine. although i cant tell from your pictures, if you do have the engine out of the car get new piston rings just to cover your bases

Well, they deffinately have oil burnt on them... hard to tell from the pics. From the top they look like crap :wink: but most of that will probably wipe off. Hard to tell from the pic. Get a pic of the crank if you can. And of the piston itself out of the engine if possible. Are the tops all chopped up and scratched or are they in decent condition?

well found something else today as well, my head gasket had coolant passageways blocked...like its all clogged up from gunk and crap fromt head i guess. 4 or 5 holes were pluged up. but i drained the oil and about to take the pan off then get to the pistons. wish me luck
