So, for years and years I've been misled. Flat tappet cams were the crime - subject to cam break-in failure and then keeping zinc in the oil thereafter. I've never lost a flat tappet cam by the way. But now my roller cam/bronze gear in my van is putting bronze flakes in my oil as it shears away each time I drive it. Now, there is a 90 dollar solution in the Crane melonized gear (without shaft). But, it should be placed in new when the cam is new. I have another roller cam heading my way, an Oregon grind. Is it billet? Is it a stock regrind? Do I use the Crane "90 dollar wonder", or can I use the factory gear drive? Flat tappets have been issue free for over 3 decades to me. Now I'm going roller and my troubles begin.... starting with a gear shearing unwanted substance in my oil. As Tony The Tiger would say.... GRRRRRRREAT!!!!!!!!!!!! :BangHead:
