Question white exaust fumes, oil consumption?

So I found my dream car, this great white shark of an '85 GSL-SE (13b) for an amount I couldn't refuse from one certain slavant-of-sorts mechanic; bless this doods soul, 200,000 miles on it and it runs like a 6 year old virgin trapped on Michael Jacksons estate. Cruising at 120 mph/ 4200 rpm's a guy can't help but notice the Pride of this beast as it sings some fibonacci on the scale of pi, the hard work I have already put in under the hood since i bought it last month has been more than worth it, its almost disturbing how tactile these cars are; how responsive they are to an elbow room of human will, how, once you listen with them Karate Kid ears it becomes possible to tune those specs to your personal likings as you tune a radio. Now... sentimental value aside, it would be most appreciated if those guru's of the golden ratio could illustrate factors contributing to burning off engine oil Painfully simple question, i know, but also a very broad one. I can say that I've spoiled everyother aspect under the hood except for the fact that the last two rounds I filled it with 5-30w PENZOIL (let the insults fly, tech wonders. Please!) but i think the problem lies deeper, and keepin them apex seals happy is the one venue I'll not meddle with (aside from, again, PENZOIL, ugh). I'm leaning towards throttle body adjustment over component failures, every single piece within it is stock and it just passed emmisions as though it understood life is a teacher, your gonna get tested.
Much obliged to any and all support, including hate mail from the Michael Jackson fans. I know I know, "he made Thriller".

LMFAO. That is probably one of the funniest posts I have read in a long time while still showing your passion for the car. I only recently got my '79 running and had my first experience of the sound of a rapped out rotary.

I also have a probelm with exhaust smoke. I changed my oil fairly recently to 5W-30. When I drive it though, once I hit around 4,500 rpm's, smoke starts rolling out the exhaust. It is a grayish color and subsides when I go back under that 4,500 mark. I want to figure out how to take care of it so the police doesn't pick me up for fogging for mosquitos without a permit. I told my dad it is my ninja disappearing trick. If I have someone following me, I rev it up and start smoking, then I disappear.

Good luck on getting your problem figured out and congrats on the new car.

...can't believe I just read all of that one... (try hitting enter a couple of times in the next post, less painful on the eyes )

How much oil consumption are we talking here? The rotary engine is designed to burn a certain amount of oil as it drives, by injecting it into the intake charge, in order to lubricate the apex seals.

Additionally, does the white smoke smell like coolant?

That 5w-30 is a little too thin for your seals, but I'm sure you saw that coming. Wait a couple of weeks and I think you can add a quart of 20w-30 to thicken the mixture up a little. If the weather over in CO is still cold then that will also cause your car to smoke more than it would if you had warm temps.

Also read up on how to adjust your TPS. This can be the cause of many idle problems and overall efficiency of the fuel injection. The other main sensor to check is the coolant temp sensor behind the waterpump. If the coolant sensor has gone south then the car will be running mostly cool which will consume alot of extra gas.

Look at threads from Longduck and GSL-SE addict

Make sure that you have not overfilled the system. Too much oil = smokie

I won't lie, I didn't read this whole thread. But the rules go like this:

Blue Smoke = Burning oil
White smoke = coolant (a small amount is normal as a vehicle warms up)
Black smoke = Vehicle is running rich.

What about no/very little smoke under 4,000 RPM's and lots of smoke over 4,000 RPM's?

white=water, which means blown coolant seal. (if it still smakes at normal opperating temp)

Blown oil control seals...

I wouldn't say "blown" oil control seals, more or less just worn out. Run 10W30 or even 20W50 and see what happens. The thicker oil should help prevent too much consumption and smoke.
