    If it has a nylon tooth cam gear, and teeth have mostly come off in this process, all that nylon material ends up in the pan. If the nylon isn't cleaned out, sometime down the road the material may clog the oil pump pickup. FYI.

    Thanks for the info. I'll be sure to look into that! :TU:

    I've been looking around on the places you've told me to find, and all I've managed to find is timing covers. I can't seem to find the actual gears.

    Help?

    I have several used timing sets with good chains and steel gears. I need two timing covers and a balancer and have trouble finding decent ones.

    I can find the chain and the crank gear for sale, but apparently nobody sells the cam gear.

    I suppose I'll figure out why this is when I start tearing into mine to see what the real problem is.

    Okay everybody, update:

    I pulled everything off the front of the motor and checked out the timing gear. The nylon gear has a few cracks in it, but the cam gear and the crank gear appear to be timed correctly, but when I checked with a timing light the harmonic balancer was way off the 5-degrees.

    I took everything out, and since I already have it out, I'm going to go ahead and replace the gears and chain.

    I suspect that the problem is now with the distributor... I believe that's the only other thing that could cause such off-timing.
