Hey all,

I just had a question. i had heard that rotary engines had issues with the scraper rings and that they should be replaced 40,000 miles.... is this true? or is this just some bad info? any info or advice is appreciated, thanks.

This is probably going to be stupid but what are scraper rings?

 

^^^ditto.

 

Judging from the fact that there are no such thing as "scraper rings", Id say its bad info Maybe what someone was reffering to was the apex seals (which do "scrape" against the housing, but are not rings..) But then again nothing should have to be replaced every 40k miles, barring some major engine failure. Many of us have our cars well over the 100k mark with no problems. My Turbo2 had over 140k miles on its original engine, and still ran fairly well, even after hitting fuel cut because of raised boost numerous times.

 

Maybe he is refering to the FE's extra O-ring?

 

OK the kid is young and most likly dosen't know the rite words, and my spelling sucks at times but then you you two know any thing you would just know what he was talken about and would under stand my spellen.
He is talken about the metal oil control rings on the sides of the rotors and there is a factory spec for the amount a of wair. A good rule is any thing more then hafe way worn across the face it's throw away time.
The life of these seal is almost forever as long as one has kept up on oil changes and good air filters. What is the problem is the oring in side the seal. Starting at 10 years and or 120 k mi they get hard and no longer seal. I also beleve that leaded fuel and alcohoe don't do them any good

 

^^^huh? I am confused

 

Hell I build these things and I don't know what FE's extra o rings are what a dum *** I could be making my self out to be

 

He is reffering to the Rx-8s renesis engine, has a different oil ring setup than previous 13Bs.

 

I saw a pic of the in sides of one of them new motors and that's all. may be I could pull some strings at the dealer ship where I use to work at and down load the manule

 

Damn someone beat me to it
