4 cylinder V8 Part II

[USMC302]

I was using I regular compression tester like the one you buy at AutoZone.

Whe the head gasket blew the first time we purchased a new stock head to replace it, it cam with new springs and valves, we also bought new springs and for the other head and gave it a valve job to match the other head. The rockers are stock and old (88) and so are the pushrods, they were the same pushrods that were working before the head swap. So maybe the head was milled enough to make the pushrods to be too long?! Should i shim all of the rockers? Just the cylinders that are acting up? Intake and exhaust side?

we checked everywhere for pinched wires but didn't find anything, same for vacuum leaks. I will check to see if maybe the pins on the connectors pushed out of the connecter this weekend too.

Yeah, 1,2,6,& 8 aren't firing, which are on both sides of the motor, which made it difficult to narrow down to a head or something specific.


Thank for all of this, I might finally get somewhere.

PS. When the head gasket blew, we had water in all of our oil and lifters and everywhere, we cleaned it all, including the lifters which appeared to still be ok, do you think the water in the oil system damaged the lifters?
