Re: "Acceptable" bearing clearance

The best would be to go to the .010 size. Excess bearing clearance contributes to oil burning as there is much more oil being thrown around in the the crankcase and the oil rings have trouble scraping it down.

You could however get a pretty good result by finding a set of .oo2 bearings. That was a standard service item for tired engines back in the day and there are many sets of originals floating around. I might even have a set.

And how are your rod bearings?
