All you have to do to get a James Bond smoke screen for mine is turn it on!! Now, who wants to deal with THAT? My question is.....rebuild, or forget it and get a new engine?
Shut up and start your own thread.

Also, please tell me you aren't flooring it or holding it at 5000 RPMs when the engine is still cold. (Within roughly 10 minutes of starting the car.)
No, I'm pretty sure that people have thought about it.

Based on what he describes the oil control rings are shot, as has been stated before. Same with the poster above you. My motor has full compression, probably a little better because of all the oil running around, with blown control rings and the timing is as perfect as it gets. I have very similar issues, though mines a little bit worse off since the fast idle will get it smoking.

Why did they instate the rule about not flaming noobs? I think the flaming did a good job of keeping idiots to a minimum.

Ok, I'm glad to hear this sort of response. Now I know a little more about rotaries than before. I had this similar problem but it actually turned out to be a timing issue. I wish my engine had full compression.

That's not exactly what I meant. What I am getting at is that; low compression, due to apex seal damage, does not cause the loss of 1 qt oil/300 miles. Someone else had insinuated this fact.

If you're going to tell me I'm wrong, at least take the time to prove it.

First, I didn't tell you that you were wrong. Hence, the question mark at the end of my sentence.

Second, with the above said and looking at the quoted statement alone, you're wrong. Less compression = less efficiency = worse burning. It will have an effect on emissions. How much, I have no clue (I live in TN, we don't care about emissions ). Now, as far as the smoking, I guess it depends on how you lost compression. If you're losing compression from an oil seal being shot (not what's being talked about here directly), then yeah, that could cause smoking.

However, now that you clarified your response, it seems you're only partially wrong. No, I really doubt that much oil burning could be caused by the loss/damage of an apex seal. I'm not sure how it would, but I can't say it's impossible...

If anyone wants to tell me I'm wrong or correct me, go for it. I like learning new things.
