Yep, it's
zinc that is missing from our life blood
oil. Several additives are out now. I rebuilt my 428 back in 2004, due to breaking a rocker shaft. We were headed to "Americruise" after shoveling down food at Village Inn. I heard a pop, shut it down, pulled over and didn't see any problems. Fired it back up, sounds sick but, went ahead to the show. The next morning, I took the valve covers off and at #1 cylinder, the rocker shaft was broke, both valves stuck shut (how'd that happen
and the intake push rod was bent 90 degrees inside the manifold ! This time, I bought END STANDS ! lol
FE'S ???
