Wipe off the piston just using a clean towel. Now take a small ball-peen hammer and lightly tap on piston head and skirts. What you are looking for is stress cracks, if there is any the oil will come up out of them with the tapping.

hey Mo, if you took a little propane hand held torch would it not pull the oil to any cracks without beating on it????

Tapping lightly will work....never have tried a torch.

Is that a TRW L2268 +.060 427 piston? flatlander racing has them for $68 each. I'd replace it to be safe.

Good luck, BCD.

It´s MUCH cheaper to buy one of these in the US than in Sweden. Sam is going to ship me one, so I´ll be on the safe side.
You always learn something.
Thank´s !
