Re: Best Way to Unseize an Engine

Hi Scott,
I agree, In most cases I look at the piston as being the part to sacrifice if needed as well. Years ago after learning the hard way with the grease method I made a piston pulling fixture that grabs around the rod on the wrist pin end and pulls the piston out through the back side of the bore. ( done mostly on single cylinder Rowboat Motors and opposed twins ) one of the best tools & fixtures I have made for working on Rowboat Motors. there has only been one piston that I have not been able to get out to date that I had to machine out. But much like yourself a good cleaning, hone and in some cases a new used piston & rings it was back up running with nice compression and bounce. I have pulled out a few pistons for fellow club members as well.

Respectfully
