Well, I know the effects of of having piston ring chunks in the combustion chamber and boy howdy...it aint pretty.On the other hand, I have also seen what happens when aluminum piston chunks go up there as well. Result were these ingot like things resembling a pool of melted solder on the piston face...cept they were hard. I would just use plenty of grease will doing the tap and have a shop vac handy for afterwards to BE SURE you got as much out as possible.
