Goodbye Crane Flat Tappet. I hardly knew ye.

be very very careful with oil choices guys. even the diesel oils like rotella are taking out the zinc. I use the brad penn oils. they are designed to work specifically with out mech. lifter cams. its $7 a qt at my local speed shop. Knowing an oil company is making an oil that is specifically designed to work with our old school cams why the heck would you use anything else?
