Soooo... I have my 361 up on my Harbor Freight engine stand waiting for it to colapse on me while I'm doing the rear main seal. I get curious and peek into the cylinders from below. I notice a few of them have one decent sized vertical score that you can definately feel with your finger or nail. Some are about an inch long and half inch across. I only drove the car home about 50 miles when I bought it. I seem to run fine and sounded ok. Then took engine out for upgrades. The vertical scores are below what looks to be the really smooth area that the rings create on the cylinder walls. The walls are nice and shiney and none of the scores go up that high, they stop right at the bottom of the shiney walls. Engine had oil pressure on the after market gauge .. about 40psi. So, is this ok? What is this from. .... perhaps a blocked oil pickup tube ? my next post. -- -- Please address private mail -- mail of interest to only one person -- directly to that person.
