unexpected example how "not to do" it or should I say something for the "hall of shame". the condition of Prez 356 pre-a piston/cylinder kit was ok but they needed an overhauling. luckily we found a company who offers this since the engine should get its original p/c kit back and no repro ones. so we boxed up everything in a HUUUGE box to make sure that nothing will get damaged on the way to the company. the pictures show how the p/c kit came back after the overhauling ... any comment is unnecessary. just check out the pictures and make your own opinion. just as side note: the cost of that overhauling was comparable with 10sets of Mahle Typ1 p/c kits (when they were still available)
