318 Piston identification

In my experience, you want to go through it yourself. Not many are really good at rebuilding engines and cheap out buying parts for the short term.

This would be the 8th engine ive rebuilt, and 2nd 318, last one I rebuilt was for my wife's Fifth Avenue the rest were 4 cylinder engines. I just hate when someone trys to make a sale on "rebuilt engine" and it could of been redone by some idiot that shouldn't be rebuilding engines. Ive ran into that before. better safe than sorry.

As long as parts are still in spec to my factory manual and no signs of cracks or other damage, clean them up and reuse.
