    Another quickie.

    Is the camshaft gear supposed to be a cheesy poly-plastic sorta thing and not steel? My crankshaft gear is good ole steel. Is my crankshaft some aftermarket thing?

    crank = steel
    camshaft = fibre
    factory set-up

    Isn't it phenolic, fiber reinforced? AFAIK this is an early structural composite, and was used to reduce the noise from the gear drive (gear driven can whine like a blower). The V6 used a nylon-toothed OEM cam gear for the same reason.

    That's what it looks like. Just didn't know what it was called.

    It is 'cheesey' for a reason.

    It is a sacrificial gear.

    If anything in the system gets locked up the gear will go without taking the internal hard parts.

    It is usually standard to build a sacrificial link in mechanical chains so that collateral damage in case of a lock up are minimal
