I was wondering of someone could tell me if there is a difference in the way the rotor seals received lube in the 2nd gen rx7 N/A compaired to rx8 Renesis?

The reason I ask is I have owned two 2nd gen 7's and both went well over 200K miles without any problems at all. Since I bought the 2004 RX8 ( all recalls have been taken care of) all you see on the web is how the seals do not get enough lube and will cause early life failure. I am not a rotary expert by any means but I have owned a few and I do understand the engine.

I use the car for work and I travel about 500 miles of highway travel every week. My baby currently has 22K on it and no trouble other that a leaking oil cooler that was fixed under warranty. I just keep wondering if there is something extra I should be doing to help the seal life like a high ratio premix?

I just cant seem to see why all the fuss now with the Renesis! Am I missing something?

Thanks

 

The FC used 4 oil injectors (dribblers) and in the case of the 86-88 models a mechanical MOP.

The oil was injected both into the engine and in the intake tracts.

The mechanical MOP was consistent which meant more oil usage (entirely dependent on throttle position) while electrical controlled MOPs such as used by the FD (which only had two oil injectors) or FE are load and throttle position dependent and will have less oil usage and more controlled flow when compared to the earlier designs.

 

Yeah, what he said!
