me and steve took my motor apart again last night and seen something unusual...the apex seals seem to have been chattering near the ported exuast port..what my question is is what could cause this? maybe the rotor housings i bought had been overheated before? metal warpage? i hope this isnt the case cause i bought them off a reputable forum member? anywho if anyone has any ideas or info let me know....jr ps this is only after 1,500 miles...

Are you running a BP by any chance?

nope just a moderate street port..

 

Thats a huge exaust port.

 

must look bigger in the picture its not that big stage two from rotaryheads

 

Seal chatter - What apex seals? What apex seal springs? And do you hold your motor at very high rpm's? And if soo what's the highest you've brought it up to? Has nothing to do with the housing. But more your driving style and apex seal/springs of choice.

 

used the 2mm 2 piece ra seals with oem springs..i may have brought it to 6,000k never brought my fc's all the way to redline..

 

What kind of engine oil?
Do you premix? If so, with what kinda premix?
What kinda gas do you use?
Water injection?


-Ted

 

no premix using omp..castrol gtx 20w50 and no water injection

 

I could only imagine the springs causing that to happen.
