Unorthodoxed Racing Crank Pulley=Crankwalk?

[doug]

I've seen several accounts on here of guys saying they had engine damage from a failed pulley. I don't remember specifics, and if weren't such a lazy ass I'd search and post the links.

I would also be in line for a metal timming cover. HHHMMMMM perhaps I should try and see how hard it would be to make.

I should get a freebie for coming up with the idea!

Heres my vote for a metal lower cover.

How does a pulley delaminating cause bent valves?

If you drive it with the hideous noise emanating from the pulley for three weeks while waiting for an answer you like to be posted on DSMtuners (instead of the ugly truth), the loose part can wander over against the timing belt dust cover, cut out a large enough chunk for the cam belt to grab, feed in between the belt and the crank sprocket, and voy-la! Shit for a motor.

If any of the vendors start making metal timing belt covers, I'll be first to buy.

It better be damned thick, and made of aluminum to prevent sparks. Die-cast might be nice.

Exactly.

Hmm. I have a set of UDR pullys but not the crank pulley. I really dont see how just using the UD pulleys and not using a non harmonic dampener pulley will cause this issue.

I just want to be sure though, because these would be going a 95. Maybe it is just not worth the 3-5lbs of weight savings....
