Nevermind Im blind. Didnt see you said new housings were used.

Are all the seals good? You keep saying apex seals, how about corner seals, side seals are they all good too? It would have been nice to know what the knock went to, so you could tell if that is what happened. Pictures? It of could of been the diffuser if everything else is good, hard to say though. Other than that I can't think of anything else.

I will try and explain a bit clearer the damage.

REAR ROTOR

Diffuser for primary broken off, must have gone in engine

All apex seals, rotor and rotor housing trashed.



FRONT ROTOR

Everything is good, apart from one cracked side seal,

three inch long gouges under the exhaust port and a

small mark on the rotor.

Also their is evidence of the rotor face hitting the rotor housing.



Do you think tuning would cause this? or some foreign objects getting into

the intake?



Thanks

i would think that the rotor face hitting the housing would be a fucked up bearing issue

1. Apex13B would be right about the rotor hitting the housing. I too would lean at the bad stationary bearing being responsable for that.

2. As for the gouges in the front housing I would suspect the broken side seal was responsable for that.

3. As far as the rear rotor is concerned who really knows for sure. I mean it sounds like this motor had issues before you even started tunning. (Pictures of all the parts your referring to would defintly help with this), but anyhow it sounds like in addition to a less than perfect rebuild you had run into some tunning isssues that put you in a pre-detenation situation, which we know is never good.

4. You also mentioned gouges in or around the ports this can be contrubuted to an over "porting" of the port openings allowing the corresponding seal to fall into the port instead of passing over it cleanly as it should.

2. The side seal was just cracked it had no damage.

4. All the apex seal are in good condition.
