last month after doing a partial compression test? So I ended up putting in a mechanical guage, and pulled the distributor, put a drill and shaft to turn the oil pump....Well I had the valve cover off so I could see if the oil was flowing out. Well, I dont remember for sure but I think I was a bit worried then because even though I could get some oil pressure with the drill no oil was flowing out the valve train. Thas because the crank had to be either at 10 or 1 o'clock based from TDC. I didnt think of that at the time of testing, but in a case where you are pumping up oil pressure on a fresh rebuild that would be good to remember if you want oil to the upper end.
