Sadly, that re-pinching process will not add any life to your engine.

It will however, result in an out of round sleeve with a tight spot or two, fooling you into believing that you have added 'pinch' back to the engine.

The piston and sleeve will wear quickly, leaving you with a dead mill.

BTDT.

I've tried every method of re-pinching an engine you can possibly think of and only one works.

This is the same procedure that the factories use to 'pinch' a sleeve when they are made.
