Hi everyone,
Looking for some guidance in trying to find the root cause here.
My engine has been fully rebuild from the ground up and had perfect compression ratio, oil pressure and overall drivability during the first miles. However, after only 50 miles a knocking sound appeared which had me worried so it was torn apart again only to find major damage to the brand new JE pistons and Mahle cilinders. Only 1 cilinder suffered from compression loss but I'm amazed the other ones had not already as well...
The JE piston set included a special order compression ring set which came in the package. I'm thinking along the lines of compression rings delivered for cast iron blocks instead of Nicasil coated cilinders but again... puzzled by this.
Anyone has an idea? I'm looking at buying a full new set of pistons + having to re-do all cilinders.
Kind regards
