Smoking engine? Check piston and rings for excessive play.

Thanks for watching

Piston is always smaller on the. Pin line, tighter fit cross wise,,,, that is, thrust side, across block

Nice

Depending on the manufacturer that may be more than just excessive TBH that looks beyond the service limit!
you may need a new piston w/ rings, and honed cylinder.

I agree. That engine was scrap anyways.

clean off the tops of them grind

No, that movement is correct because the engine you're touching is cold. When it heats up, rings expand.

Well…… actually the rings were bad. This was a trashed unit and the clearances were way off. The engine smoked and after testing, we found the rings and cylinder were very worn. A lot of piston slap.
