    getting better

    well, I've managed to improve my leakdown percentages. With the oval cylinders, I got 50%, now with round holes I get 60%. Maybe a few more rebuilds and I can drive down the road at 100% leakage and break all the laws of physics.


    Leakage appears to be past the rings, I can hear it hissing out of the oil fills on the valve covers. Compression is 140-150 on each cylinder, and ramps up slow. Compression is about 175-185 with oil in the cylinder, and ramps up normally. 4000 miles on the motor and its crap. Anyone have any thoughts on any magic tricks I can try to get the rings seated short of me pulling the engine yet again? I have a feeling they never seated properly on initial breakin, probably I was too easy on it.

    Coast down a few mountain passes in a lower gear to make the high-RPM vacuum try to suck the rings into place

          nah, tempted to just dump the clean motor in the river and put some greasy nasty pos in there. I'm tired of pulling engines, this makes a planned #4. I've done the high speed low gear coast thing just as part of normal driving, I hate using the brakes coasting downhill. I wonder if I can just use a bottle brush hone in the bores, and stuff it back together with the same rings.
