I've been hearing more and more about people with early flat-tappet cam/lifter wear....related to the quality of the newer formulated oils. Recently, someone told me of an article in Hot Rod about this subject; I didn't see it.
I've got about 3,000 miles on the engine in my Model A. (with 4-banger Mercruiser w/solid lifter cam)
Does anyone know how prevalent this problem is.....or if it's true? I've used Valvoline 10W-30 for years and never had a cam, lifter, or bearing problem, but not I'm getting nervous. I do NOT want my cam, or lifters to go bad.
