Iv'e had similar results with Wossner pistons, I was using Mahle 3.6 cylinders, all replated to original spec. not positive but suspect short light wrist pin. However It could have had a rod bearing let go, since it was rebuilt with suspect Glyco rod bearings, I also have 5 pistons and cylinders 1 hr. run time they might be fine but who wants to take a chance.
