If been searching on the OMP and it's operating characteristics, but I seem to be missing something.. And I think it's related to my car's strange smoking habits.



I drive 1 mile to work. It's on a Aif Force Base. 30 miles an hour, VERY minimal boosting. I work 8 hours, get off and start my car. It smokes (oil) for like 30 seconds until it starts warming up. After that, it doesn't smoke. This is the only time it smokes to this degree. It usually only lets out a little white puff of smoke when I start up...



I know burning oil is normal, but does the OMP add more oil under light driving? That doesn't seem to make sense but seems to be that cold startup after light driving = more smoke. If I cold start the car after more aggressive driving, the smoke isn't there...



Any ideas?

IMO I think that it might be your turbo instead of your OMP. Yes the OMP squits oil in but it shouldn't be alot while doing some light driving. IMO the reason it smokes more after light in comparison to heavy driving is that your seals aren't as hot and tend to shrink faster. You may want to check the seals on the turbo and the motor. There may be a couple of bad ones.

Goddamit... I don't feel like pullin this biatch apart yet... :( Oh well...



I guess I'll drive it till it melts.... https://www.nopistons.com/forums/pub...

That's up to you man :( . Sorry that this is happening. Atleast this way you have a good excuse to go with a large single turbo setup https://www.nopistons.com/forums/pub... . Then you can do this https://www.nopistons.com/forums/pub...#>/BURNOUT.gif alot more. B)

could also be the oil seals going in the engine like already mentioned :(

Wait a minute.....you said WHITE smoke. What color is it??? If your burning oil its a blueish color. If the smoke is white its coolant. During the winter they smoke white from condensation buildup in the exhaust but its not winter.



You can do a compression test on your cooling system over night and see if the pressure drops.



I hope I'm wrong though

Reason I said it's oil is cause it smells like oil. Not coolant. Looks blueish tho...But it's weird because it only does it sometimes. Mostly when I drive short distances, without boosting...



Scenerio 1: Wake up, drive to work. 1 mile. 30 mph. No boosting. (or minimal) Get off work 8 hours later, car smokes for the first 30 seconds or so. Thick, oil smelling smoke. Goes away COMPLETELY after warmup.



Scenerio 2: Wake up, drive to St.Louis. 75-80 mph. Full boost runs... regular, but not over agressive driving. No redlines.... Park car. Next day, start car. No smoke.



When I start the car in the morning, whether or not it smokes, depends on where I went with it.... SO ******* WIERD.



BTW, THANKS FOR THE INPUT!!!! I posted this on the bastard forum and got ignored. FAWKERS.

Mine does the exact same friggin thing. I thought it was normal :unsure:



How do you know if its the turbos in particular causing the smoke? My car runs 7psi on first turbo and 12psi boost on the second turbo (which I already know is asking for trouble but it how I bought it 6 months ago) https://www.nopistons.com/forums/pub...>/rolleyes.gif Should I be getting the turbos looked at. Ive been wanting to dial the boost down to 10psi anyway.

My car does this normally...but I also KNOW that my primary turbine's blown...so I'll run her into the ground until I can go big single turbo :bigok:

Maybe the car isn't warming up enough to clear everything out?

Sounds like my NA FC has been since I bought it, but it started getting really bad recently and I'm rebuilding the motor now. It's most likely the oil control rings (the circular oils seals on the sides of the rotors) leaking oil when sitting still. Once you start it up, the oil goes into the combustion chambers and produces smoke. I had it foul my plugs a few times too, to the extent that the car would not start without cleaning them. This was after it got quite bad though and wouldnt stop smoking til like 5 minutes of running. At least when you rebuild you get the opportunity to port the housings https://www.nopistons.com/forums/pub...IR#>/smile.png I think the main things that can cause these seals to fail prematurely is 1: driving the car without letting it warm up completely (or letting it do the AWS (idle at ~3krpm during warmup) causing excessive-unlubricated-uncooled wear on these seals and 2: leaving the thermo-pellet in the front of the eccentric shaft which cuts most oil flow to the eccentric shaft and consequently rotor bearings and rotors (used for cooling) which seems like it would put more stress on these seals, especially during warmup (or driving with a failed thermo-pellet). I've since installed the thermo-pellet plug mazdatrix sells and will be removing the thermo-wax on my FC throttle body. I'm not sure what the setup is like on the FD though, but I am sure the FD still has the thermo-pellet, and it should be elminated with the plug as a reliability modification. However, if your oil control rings are already worn, and you do the thermo-pellet mod, it seems to cause it to smoke alot more at cold startup than before, due to it permitting complete oil flow to the rotors during startup where before it was restricted. Fortunately, leaky oil seals are more of a nuisance than anything, I took my car on many long distance road trips with the seals going out and never had any problems, other than dirty looks from people when I would start the car https://www.nopistons.com/forums/pub...DIR#>/wink.png just had to keep a case of castrol GTX on hand

If it is just the short distance trips that make it smoke, you could always just bike the mile and save the FD for longer trips. By the time you let the car warm up it would probably take you just as long.

the turbos seal dynamically, if they arent spinning they dont seal as well, maybe it gets all loaded up on your drive to work. maybe you should pull off an intake pipe and see if its oily in there?



mike

There is a little oil in the intake tract... and the thing about the turbos not sealing as well if they aren't spinning sounds VERY logical...



But, funny thing is, car hasn't smoked since my last post, and I drive it everyday!



WHATEVER.... https://www.nopistons.com/forums/pub...#>/biggrin.png

i say leave it alone until it gets worse



mike

My thoughts exactly

Thanks fellas!!

i dont think it has anything to do with the turbos because my 8 does the same thing smokes on start up after light running and mine is stock non turbo ...................

its kinda embarrassing to smoke out when you start up looking for a fix if anyone figures it out ..........

Old thread but...the OP mentioned "white smoke" That suggests steam, which suggests coolant seal issue.

In your case, if your talking burning OIL (blue smoke)...Oil control rings.
