    Yes, probably 20-30 psi. Still low, but high enough it should run.

    In my humble opinion you have been lucky that the engine did not start. If you find pieces of metal in the sump they have come from somewhere and if it had started it may well have wrecked the entire engine. If it was my car I would pull the engine out, strip it right down and measure (or have measured) the main bearings, big ends and bore and check over the camshaft, followers and oil pump. Then I would rebuild it with new gaskets throughout.
    For specialist measurement or machine jobs use a local engine reconditions, most of the work you will be able to do yourself. If you start the engine without doing this you are asking for trouble.

    This step by step video shows how even someone with very little mechanical knowledge can rebuild an Alpine engine to a high standard.

    You wont get the correct compression reading without WOT ... 2 things i would worry about with your issue.

    1. Very big difference in compression between cylinders. Implying there are potential issues.

    2. As eric mentioned early on.. The motor ran without oil psi... Even if the issue was caused by a temporary blockage... The bearings msy have been starved and damaged... If you heard a loud ticking or knocking at that time.. They were getting a hard time.

    Hi, sorry for the delay in my response, between my kids, and the wife I never get to use the computer at home. I appreciate all of you helping me with this! So I redid the compression test with the throttle wide open, all the plugs out and I got about 5 psi more on each cyl. So now I'm at 12o, 125, 145, and 145. The engine did knock for just a few seconds before I pulled over to the side of the road and shut it off. But I haven't had it started since then. So you guys think I need to rebuild the engine?

    At the very least you should drop the oil pan and see what's in there. You can also
    pull the rod caps and have a look at the bearings to see if they are OK or not. If you
    had a knock, you'll find one of the caps ( probably #2 or #3) is loose. Those two generally
    get starved for oil. If that's the case you're in for a rebuild and some crankshaft work.

    Hope that helps.
