Piston Slap: A Fireball of a 3.8L Oil Leak?

Robert writes:

I have changed the seal 2 times on my 3.8L Chevy and it still will leak. I had a place on harmonic balancer.I put the recommended slave to repair.It was not long enough to cover the bad spot on the balancer.It was close but they seal was damaged.They offer a different one that is $30+.This all occurred just out of the blue.I rebuilt the engine and it has 30,000 on it.I was wondering if there is something causing pressure around this seal.Pressure check on cylinders was good.Any ideas what to do or pressure is good too good.

Thank you sincerely – Robert
