I know it is hard to do, but if you starve a bearings oil supply I know it can be done.

When I hit the gas hard, my enging in makes a chripping noise that is internal . At first I thought it was a detonation or something, but now I thing it my be the rotor hitting the housing or something like that.

Anyone have any thoughts or suggestions?

 

If you spun a bearing your oil pressure would be very low. Drain your oil and if its got metal flaking in it, if it does, the engine is over, and will need to be apart to repair. Different rotors, and stationary gears with different bearings and probably a different e-shaft.

 

yeah thats exactly what happened to yours

 

By the way I have all of them ... Well the e shaft , 1 rear rotor (perfect) and the statinary gears from a low mileage motor

 

if you really spun a bearing, why wouldn't the motor just lockup?

 

I took an engine apart that spun a bearing. Not an easy task because the thrust plate area was all self-welded together!

 

I wiped out my rear rotor bearing at a race earlier this year. It would run and idle, but everytime I gave it gas, it made a loud KNOCK sound, not a chirp. Hows your oil pressure? And do what wacky says, drain and look at your oil, cut open your filter too and look at it.

 

Bringing this thread back to life
I just spun a rear rotor bearing 2 weeks ago in my 91 N/A. What sucks is that I had only 7,000 miles on the engine!! What's even worse is that I still don't know what caused it!!

 

I've roached two motors that way....

Did any of you guys get oil on top of your motor when this happened? I had oil allover the rear rotor.
