Re: Besides your fingers….What is your fav Piston Ring Compressor?

[Pete]

quote bobw:

I use a plastic Bondo spreader. Drop the piston into the block until the first ring rests against the top of the cylinder, put a little downward pressure on the piston crown, push the edge of the spreader against the ring starting at the ring dowel pin, rotate it around the piston and the piston will drop right in. Repeat for the next ring.

On split case engines that would be difficult.
