- IMHO, your low compression readings show that the rings have not seated properly. I have always heard that you check compression before and after adding oil to the cylinders so that you can tell the

- I don't think your suggestion that straight 30 weight be substituted for multiviscosity oil for 1000 miles will result in engine damage, but I have doubts about its helping much. The rebuild was 3 ye

- Agreed. I have put over 10,000 miles on this engine. It may have had this low compression on all those miles, hard to say. I did "break it in" for 500 miles with 30WT, and then run 10W40 Castrol for

- At cranking speed (as when doing a compression check) ample air can flow past the pistons, since they never completely close off the air flow. Ditto the throttle butterflies. When they are "closed"
