Re: V8 Camshaft Durability
That has been a battle for a while. A lot of the flathead or old engine guys run Shell Rotella oil rather than the newer blends. That is what is used in a big percentage of the older farm tractors and equipment around the country and probably the world.
There are replacement additives for ZDDP available.
It seems that a lot of guys who are having lifter/cam issues are having it right at start up and break in time though. A lot of that with Chevy small blocks and I am wondering if valve spring pressure might be part of the issue.
