Does this look weird to anyone?
I took apart a motor that I thought was a stock/unmolested 273.
It was smoking and using alot of oil.
After a Freshen up on the heads it was getting around 120psi in the cyls.
I pulled the piston with the lowest 115psi, removed one of the rings and put it back in the cyl
the End-Gap was around .132 - .134!!!
I was expecting to see an .020 gap, Was I wrong?
That seems to be an overly large end gap, but have you checked the bore diameter? Perhaps set the ring at the bottom of the bore. There will be less wear there. The top of the bore is where the bore wear will be the greatest.
