A few months back I determined that my #3 cylinder was making a ticking noise, and that it was either a split piston skirt or a broken ring, based on shorting out the individual cylinders and the noise going away when I did that on #3. Today I was driving the coupe again and wondering what would happen if I just played with spark advance and retard a little bit.

Wellsir, at about the 9:00 position the ticking went away (which it does when the engine warms up anyway, but the engine was still cold).

SO! My question is: does this change my original assumption about the cause of the ticking?

I also have a similar problem with my temporary engine in my 28, and it's also on #3. Mines a metalic sound like piston slap. Have you pulled you spark plug to check it's condition and look for carbon buildup in the cylinder? Check compression? Mine has 50# on all 4 and has good power, so I'll just keep driving it until I finish my original engine and reinstall it.
