Reply to "cam shaft lobe extensively worn"

George PAdmin.

I "suspect" the problem with flat tappet cams flattening lobes, which began occurring approximately 15 years ago, was intentional, perpetrated by a camshaft manufacturer who sells a line of retrofit hydraulic roller cams. This never happens when folks use a custom cam from Bullet Cams. It never happens when Valvoline VR1 is the only lubricant in the sump.

One Warning: Dumping in a can of ZDDP oil additive will reduce the wear protection properties of motor oil, and only make things worse.

Uli I would still like to know the name of the cam manufacturer.
