So, I replaced the head gasket because of low compression in cylinders 2 and 3...around 50 to 60 psi. Now with the new gasket and Moyer used Head I'm not sure the compression is much improved. Engine is still out...in my cabin.
Also, while having the head off I filled all cylinders with an ounce or so of MMO on several occasions to prevent them from locking up and to free the rings, in case that was an issue. By the next day MMO was still in 1 and 4 cylinders but not in 2 and 3.
There is nothing attached to the engine right now so I can't start it to test compression. Here are my questions:
What would compression numbers be like just hand cranking? (have not tried it yet)
Is the MMO seeping passed the rings an indication of anything?
Should I continue with MMO treatments assuming it will free the rings? (in case that is the cause of low compression)
Can I remove pistons and rings without removing the head? (I destroyed one head already and all the studs using the wrong puller)
