Cam lobe going flat...what now?

OP. For your consideration

During my career, I've replaced cams with worn lobes in dozens of cars of all breeds. Dealerships won't pull an engine apart for a worn lobe, but will maintain the warranty for duration, cuz motors generally aren't noticeably affected by the failure's debris.

It just isn't practical to tear down every engine that eats a lobe. Having torn down engines with worn lobes, I never did find any debris other than grey paste in casting depressions..

I have maintained some of those lobe eating cars for decades, and never had a failed lobe debris issue.

Have faith in gravity and the oil filter.

However that's not to say pulling the pump isn't a great idea.

jmo . . hope it helps
