Re: "Acceptable" bearing clearance

PackardV8's suggestion about checking the clearances at several radial locations on the crank is best practice and he's right of course, you should do that check.

But I can't agree about a 40,000 mile service life for those engines, assuming good care they were good for far more than that. And a "warranty" claim would not have used 0.002 undersize bearings, the warranty period was only 30 days, was it not? Hard to think anyone engine could get amount of wear in 30 days and if the engine did show that much wear within the warranty period, I suspect Packard would replace the engine or do a proper repair or disclaim it entirely if there were signs of customer abuse (like running with no oil).
