I'm trying to fix an oil pressure issue after a engine rebuild. This is a follow up on loss of oil pressure question after engine warm up that I got into several months ago. The I finally got around to pulling engine and removing pan. I pulled the mains and have some scoring of main bearings (probably because I ran it too long with low pressure as there was fine metal in bottom of pan) so I will have crank ground with new bearings. Oil pump was looked at by mechanic and he thought it was fine. I did something unconventional and rigged up a pressure sprayer with oil and connected it to block oil port and pressurized it with oil (with bearings back on) and it was squirting out of front cam journal (in engine)! There seems to be a notch on the cam end and the oil only leaks out when the cam is in a certain spot on rotation. I have no idea if this is normal but would think it would affect oil pressure. I other suspicions on issue but I will would tackle this question first. Cam journal was supposedly checked when engine was worked on. Thanks for any help. Bill
