Well, the PCV valve rattles OK, but is covered in oil. Have not run a compression check. I know I should, but I'm dreading the results. Definitely High crankcase pressure. Oil is leaking at distributer hole, and at the top of the timing chain cover. I'm kicking myself now for listening to the guy I got the engine from. Said it was in great condition, just had a flat lobe on the cam, but everything else was fine. I did mic the cylinders and very little wear. Should have gone ahead and done the rings THEN! I'm so disgusted right now, that I'd just as soon find a good 350 or 327 and replce the thing! Anyone nearby Shreveport got a good SBC for sale?
