[H. L. Chauvin]

FWIW:

I remember having an oil burning, smoking Model A engine years ago in my well-used coupe which I bought as a teenager.

A kind neighbor over 55 years ago gave me a new set of piston rings that he had stored for about 20 years ...... but .... they 0.010" larger than my engine bore.

I asked a vintage professional machinist/mechanic if he thought installing these rings could harm the engine.

He said the cylinders may become slightly egg-shaped ...... but since this is a Model A, rest assured that these oversized rings will never be the next thing to go wrong with a Model A.

Unfortunately, he was correct.
