You're missing a compression number up front. It's also odd that the front rotor has lower compression than the rear. That's very uncommon.
Soaking in oil won't hurt the engine, but you'll be paying for something that likely won't help anything. With those compression numbers it really just needs a new / rebuilt engine. |

I called the dealer to double check and he said the compression in the front was definitely lower then the rear which he said is unusual as well.
Do you think it definitely needs a rebuilt or replacement engine ? The dealer said a new engine is in the $6k range ... isn't a rebuild in the $2k range ? I was searching online and I don't see any shops on Long Island that are rotary specialist ... are you interested in another side project at John V's garage |

It doesn't *need* anything. If it runs okay with new coils and plugs, drive it. If you get sick of it, sell it. The low compression is unlikely to be fixed with anything other than a rebuild. There's an off chance that their oil-soak could do something, but my guess is it won't.
Engine rebuild costs depend on what needs to be replaced. It's possible to do a tear-down, clean the carbon off of everything, throw new seals and springs at it and slap it back together for under a grand. Such an engine will run fine and likely give many years of service. A full rebuild will involve evaluating all of the housings and the rotors and determining what is good and what needs to be replaced. New rotor housings are upwards of $500 each for the RENESIS. Side housings usually can be reused, but they're on the same order of magnitude for cost if they need replacement. I don't remember how much RENESIS rotors go for these days but $500-$1000 each doesn't seem unlikely. So a "full" rebuild could easily cost $4k just in parts. I do like rebuilding rotaries but I don't see myself wanting to take that on in the near future. I have a pretty full plate right now. |

Ok good news ... just got the car back and as the dealer mechanic put it .. it is running strong. Still not the fastest thing but it is driving like I remember it should.

Took out the RX-8 today and I have to tell you this car is really fun to drive ... I really am enjoying it, it is pulling strong and feeling great. It needs bluetooth and sirius radio but I'm sure there must be some simple solutions for this ... plus if it was red, black or white that would be better
Here are a few cell phone pics ... |
