Bluish smoke and some minor blow by. Maybe rings? Could I get away with using 20w50 oil instead of the SAE30 that is in there? Would that help with compression and help to stop burning the oil? Or should I just do the rings/? [Reply]   [No Email]

You don't need to start thinking about doing anything to the engine internals until compression gets down around 75PSI. I can speak from experience, going to "thicker" oil makes NO DIFFERENCE, period. Doesn't help oil pressure. Definitely doesn't do a thing for compression. You might have some oil coming in through the valve guides. Work the snot out of it if you can. Another option is to get it warmed up and spray 1/2 of a can of Seafoam directly into the intake with an old Windex bottle as quickly as you can without killing the engine. Should clean it up.

The valves have to be pretty good too or you would have more spread in the numbers. Put some clean oil in it and make it work, chances are the more and harder it works the rings will seat and it will clear up. If not , with those numbers I would think it has to be getting oil through the valve guides if its burning it. [Reply]  [No Email]
