in a non turbo application theres a few little bits that can be problems on a stock engine.
ive seen the tension bolts snap, they apparently hit a resonance around 8000-8500 rpms, its very rare, and you can put rubber or silicon on the bolts to fix em, or now the cool thing is/are stud kits
2; also rare, the stationary gears can break, the factory has had hardened gears available forever, and all the 89+ cars got em. this problem is more akin to wear, its not the 1 run to 11,000 that kills it, its the 500th...
along with #2 the gear can walk out of the rotor, and hit the side housing, this problem has also been incrementally fixed, they keep putting more roll pins in there.
also the oiling system seems to suck over 8500, theres several other threads about that. we revved our motor to 9400, and the bearings took quite a beating, although everything else looks ok
Was your oiling system stock?

when? it was stock until we decided to spin it to 9400 (from 8200), then it got the fd oil pressure regulators. thats where the bearing issue started
