Hi Rob, Thanks for your answer. Im dont sure if I get you right: The ordered piston was without a slit and you machined it by yourself and after this the halves sprung out? Can someone tell me the meaning with the slit, will the engine work without it, or will it cause some seizure problems. Regards...

Hi everyone,
I am new on this forum. Does anyone have any experience from the NZ repro pistons sold by Oldtimergarage in Poland, the price is ok, but how is the quality?
