Small Block Oil Pressure
I rebuilt a 307 Chevy about 5 years ago. It is mostly stock internally with roller tip rockers, Comp Cams cam, edelbrock performer manifold, carb and headers. The motor has sat in this car and maybe...maybe has 1-2 hours of running time, mostly idling. I hooked up a $20.00 mechanical oil pressure guage, and the pressure seems to run at about 45 - 50 lbs while idling. It moves up and down a little while revving up to about 3000 rpm max, but not much. I have 10-40 weight Castrol oil in it which is fresh, maybe a week old. Does this pressure seem normal for a fresh rebuild or?????? I did not prime the system before starting, I just put some oil in the cylinders and after a few days, I turned it over a couple of times and then let it sit. After about a week, I fired it up. Overall, it seems to run fine. When I started it, there were no noises such as lifters etc. It does have hydraulic lifters in it as well. One other item. I noticed that the flywheel inspection cover had a small oil drip on it, I wiped it away and after running it a bit,it was back. Rear seal......I hope not. Do these ever possibly reseal themselves after some running?
