Compression test, dry then wet. I don't think that a warped head is the problem with #3 cylinder. More than likely worn or stuck rings since that cylinder is pumping oil - fouling the spark plug.

Just go ahead with the SeaFoam treatment, work the engine. It may take a while for the rings to free up - maybe never. In the mean time, you will probably continue to foul the spark plug. Next time you have to replace the #3 plug, go with a hotter plug and open the gap up a bit.

While you are adding Seafoam to the oil also add it to the gas. Then work it.

You need to use solid copper core wires. If you have resistor wires, they will contribute to your problem.

Jim, my wires are solid copper core. I haven't changed anything since I found the fouled plug. It is still running like a top.
