Ok this is the third used engine I have obtained. This one from a friend. He gave me his word on how well it ran. I trust him on that completely.
It had an oil leak from the head gasket I noticed after I got it to my shop. I took off the head and brought it in for checking at a machine shop recommended by a trusted Indy. Its cracked RRRRG.S***,F***,D***.
The cracks are around the pre-chambers on two cylinders. Maybe it was overheated I don't know. Now I'm looking over the block and I see the cylinder liner and block have a tiny gap. I cant tell if it is corrosion or what. It looks to be on a couple of cylinders.
Is this acceptable. Should I go get my money back. I have another head but it needs a valve job. I would get that done, but there is this question over the block now. I'll take more pics later. the battery ran out on the camera so only one for now.
