no oil to heads.

Well, problem found. after disassymbling the engine i found that the oil supply from the main rail down to the crank was all but blocked. when the block was cleaned i guess they missed all those ports. thats why i had pressure at the guage. needless to say the bearings are shot.

Dang that suxxx. Did the machine shop to the cleaning of the block? I had a machine shop one time deck a block more on one bank of cylinders than the other and actually give it back to me. They had the rotating assembly and everything to make sure it was correct. I feel for ya.
