A pro engine builder that has become a friend writes an occasional column, and according to him "....with a flat tappet cam it's not a question of IF it will fail, it's only a question of when", and when a lobe or two decide to erode the micro-fine, highly abrasive particles of the cam flow with the oil and get in every nook & cranny of the engine, after abrading your cylinders & bearings. The only way to be confident you get it cleaned out is total teardown and hot tanking the block. You may only be running it five times a year, but every time it starts it's going balls out, full torque, pulling hard. I'd say that $500 would be good insurance, and
