Yes, need to take her out and rebuild it. Its currently to cold outside so its just sitting and waiting for things to happen. :nod:

The rubber oil control rings do get bad over time and allow for some oil to pass through, it gets worse over time. Either they just dont seal well anymore or they will develop fissures, or break apart completely. I tried to stop or slow down the oil consumption with stop leak and seal sweller stuff, its no use. It may delay the rebuild maybe a month or two, but if you are leaking enough oil in the chambers that it starts to smoke its done for. Thicker oil might get you a few extra months too, but there is no way around a rebuild. I had massive clouds of smoke upon startup, then it was ok. Tailpipes went black, and the smell was devastating. Only option is take out the motor and rebuild it. I had the misfortune of having bad (clogged/bad spray pattern) injectors too, so starting was a real adventure. There is a vid on my site about starting it up. 1987 Mazda Rx7 EU-Spec | THRLL.com

Atkinsrotary.com sells viton oil control rings, they are far superior and much more resistant agains chemicals than the old rubber stuff. So thats what I use in all my rebuilds. If you ara at it, try to get new metal oil control rings too. They holt the rubber oil rings in place on the rotor and slide over the side plates, so its a wear item. Same for the oil control springs, if they are used, they loose their tension and the whole point of the oil control rings is gone. Its like installing worn oil rings in a piston motor...

Right thanks For The Tips I Personal Don't Have The Knowledge To Rebuild Her I've Rebuild A Piston Engine But Will Have To Have Someone Rebuild My Engine For Me

If you can rebuild a piston engine this should be no problem, just watch the videos and do a little reserch

Rebuilding my n/a was easier than any piston engine I've built (aside from small singles).

Just make sure everything is in spec, you have the right pieces and torque values, and it goes together very easily.

Exactly, get a atkinsrotary master kit for your specific engine and look for rebuild vids on youtube and there you go. Its easy peasy ^^
