Noticed while changing the oil on my old truck yesterday that the slow oil leak around the front timing cover has turned into a pretty significant one. I'd heard of the "Fiber" cam gear on these engines being a weak spot, and I'm sure mine has the original one in place. Seems like replacing it would be the thing to do preventatively while I have the timing cover off (Looks like a rad out grill out job to get access with pullers and everything). Question is should I replace it with another fiber gear, a cast iron gear or an aluminum gear? I'm leaning towards a metal gear, although I'm concerned about the additional noise. Also hard to call the OEM fiber gear a failure since its survived 34yrs. Anyone have any experience with these?
