Farmall M that is smoking so bad I have to do something. Lots of blue smoke; to illustrate I had a spark plug loose and oil was coming out of the spark plug hole. Other than the smoke the engine ran well until the other day when the number 3 piston quit firing due to a fouled plug. Repaired the plug and soon fouled again. What to do? I have the head off and pistons out and there is nothing obvious wrong. Cylinders measure 3 7/8 at the top. Tractor is used 4 hours per month as a hobby. Do I get an engine kit or simply replace rings (oversize) and hone the cylinders? Money is a factor.
