So bringing this back from the dead...just purchased this motor and have stripped the head off, but still haven't found any evidence of what was causing the problem.
So i'll throw up a bunch of photos
Bottom of head:
Top of head, head gasket on top:
Top of head, bottom of head gasket:
Now onto the head in between the rockers. This is the infamous 0331 head, but after looking it over I'm not seeing any cracks anywhere, not even between the 3rd and fourth cylinders.
Between 3rd and 4th:
Rest:
So needless to say i'm a little perplexed...
-Didn't see anything that indicated a blown head gasket from looking at the gasket
-No fluid (or evidence of) in cylinders as far as I can see
-No cracks that *I* can find on the head
So the only thing I can think of is that the head might be warped enough to have caused the issues? I'm going to get it cleaned up then take it and run a dial indicator across it on an end mill to make sure its within spec of runout.
Any other ideas?
