Cam gone flat? Here's a interesting video.
Right at the 20 minute mark, he hit on what may have caused the failure of the MP '528 in my car.
High detergent oil with zddp is pointless.....
I learned that the hard way. From early on, I used VR-1 with the Comp Cams supplement at every oil change.
Then in early 2021, I had the oil pan off to pound out a dent. I switched to the Redline synthetic with this rating:
SN SM SL are the highest detergent ratings available. Yeah, the label claimed the oil had ZDDP but so what? This was pointless. The ZDDP splashes on the parts and the detergent prevents it from sticking.
Secondly:
The reason for the 2000 rpm break in is because the camshaft and lifters rely on splash oiling. The cam gets no direct oiling. The oil squirts out the rods and mains and flings onto the underside of the cam and lifters. Below 2000 rpms, there isn't adequate movement of oil to reach the cam.
