I was supplied Seal pro as ACL Aussie pistons where not avaliable at the time.
and was assured they where good pistons
The fine print on the label in the box says "made in Mexico"
After stripping the engine we found #5 dia fron just below the ring and bottom of the skirt was 24/1000 !!!
This related to the position of the knock with a stethoscope.
All the other pistons also have a similar thu smaller diff in dia.
The knock started shortly after 1st fire while still doing intial cam bedding in.
Such collaspe as far as I can gather is caused by poor alloy or casting as the piston heats up and or the diff in diameters where there before machining and fitting/final hone of the cylinders, the latter was checked before assembly
Im having problems with the supplier in NZ here
Has anyone had problems with these pistons?
