Over revving issue

[niterydr]

If you are pulling the trans and the head, you might just want to pull the motor/trans together and pull it apart. Put the engine on a stand to work on it, and put the trans aside and inspect it.

Brandon, flywheel/clutches love to come apart or loosen up on over revs. I speak from experience and I popped my CAS plug off too!

My flywheel bolts cam loose on the over-rev. Clutch acted funny and the flywheel vibrated so badly on the over-rev that the the crank to flywheel mating surface was pitted with molten metal.

The bearings will be replaced if they look like the need it. If they look fine, then no.

We will see more once I get things taken apart.

Jim, with your issue, what all had to be done then because of that pitting? Was the motor trash?

[scheides]

No, his motor is still running! I remember jim taking the tranny off to tighten the flywheel bolts and getting a ride in it shortly thereafter!

[Super Bleeder!!]

I've had flywheel bolt issues before. Shit was so gay.

I went crazy and used longer 3sgte ARP bolts along with nordlocks and loctite!

Same thing happened to a S2k buddy of mine after he over-revved. His "engine" was making all sorts of noise so he figured he trashed the head and bent some valves, he had it trailered to the dealer and all they found were some loose flywheel bolts. They snugged them back up and the car was perfect again.

Brandon, I didn't have a ton of metal friction weld, just a few smaller globs. Most of the the metal was transferred to the flywheel from the crank so I bought another flywheel. I had to clean up the crank by hand just a little, I have seen photos of much worse from others who have had their flywheel come loose on an over-rev. I have put another 17K miles on the engine with no issues.

Also my over rev wasn't too bad I believe it was just under 9,500rpms or right around there. It was just the sudden change in rpm that shook the flywheel loose. I have the 2.4 so I don't rev it too high to begin with.

OTOH, if you're this far into a teardown pull everything apart, get the cyl walls honed, get a flat edge on the cyl head and block, etc, etc.

Pull the tranny apart, check the levers and synchros, etc.

Polish/port the intake/exhaust runs, etc.

Put together with a torque wrench.

Why would he want to hone the cylinders on his car right now?

[FattyBoomBatty]

Hone the cylinder walls. Trust me, I'm a doctor.
