Blown piston

[1989hog]

Got me one messed up piston . Looks bad on one side. It was runnin a little rough so I narrowed it done to the valves then to my surprise pulled the head of and found a bad piston #3 all the others are good . same plugs all good cept #3 oily. any Ideas why?

It could be a number of things. Was it a hole or worn on one side? Still could have been a valve that caused the problem. Might have been a lack of oil due to a clogged gallery.

well its pretty bad but a lack of oil in that spot was my 1st thought too when I pulled the piston 5 minutes ago but the walls are too good for that I think
