    A recharged battery helped a bit, I'm trying to decide whether just to check the oil pump and bearings, or pull the heads and look. I do want to get the old pressure closer to nominal, even though it's theoretically ok at 10 PSI per 1000 RPM. I guess best practice at this point will be to pull the heads and see what is up. I must say, nasty as the outside is, everything under the rocker covers is very clean. The engine uses no oil to speak of and doesn't smoke. Of course it leaks.

      I agree with Jeffry. I'd leave it alone and just fix any leaks.

        I just rebuilt my R2 and I have 175 psi cranking pressure, but I did install a R2+ camshaft. tho id think that would of lost a little on cranking.
