Stuck valves, all day long.

I had stuck valves in my '37 237 and my '40 110. I soaked them both in Marvel Mystery Oil, Diesel, and a few other concoctions.

Pretty much zero effect.

I pulled the heads, intake/exhaust manifolds and opened up the lifter galleries; in both cases the No 3 and 4 valves were stuck open. On the '37, the tappets of the day had a dome-topped screw-type adjustment. Some moron ground them flat, and then with wear over the years, the screw face grew a divot from the valve touching it. Repaired that. Massive amount of crud on all the valve stems; it was not easy getting the "packard" script valves out of the heads but eventually I succeeded. Cleaned them up with a fiber wheel on a buffer, put them back in the engine and with the repaired tappets, the engine runs like a sewing machine.

Similiar effort on the '40 (with a '46 engine in it) but haven't fired that up yet.


Run non ethanol gasoline, and run the engine long enough to get to temperature, and run it monthly.


Thank me later.
