My car has a new engine and about 1100 miles on it. after I idel for about 8 secs, white smoke comes out the exhaust. I kept the car under 4k all throug break in. The car runs very rich. And can smell gas on the dip stick. Does anybody know if this is a tuning error?? This is starting to scare me little. Plus Im running into other problems with the electrical system. The haltech is working.. Is my engine burning oil??? Sence it running so rich it should be blowing out black smoke right?? Its havent notice it coming out when criusing just at idle. its very inbarrasing at redlights, and at toco bell when the lady at the window said " your car blowing out alot smoke back there" I know something has to be done. What makes me think its the engine? maybe becuase it come for Hayes performance. Has anybody ever had a problem like this resulting to tuning?? was it the engine please say it wasnt )

Check for loss of fluids at some point. Possibly coolant.? I'm assuming it's no condensation due to you're allready at Taco Bell. Unless you live really close to it. I'd check your coolant.

i have the exact same problem . new engine only 1500 miles . i duno either, but mine typically stops after driving it for a little while. i have noticed a small loss of coolent though.

If the smoke is white and not gray, it is coolant. If it is pumping out very much you will see a loss in coolant, but probably not a lot of coolant. It does not take much liquid to create a lot of gas so keep that in mind. Don't expect the coolant to be 4" down or anything like that. If it ran through that much it would not run.
For a fresh motor this is not a good sign as I am sure you have figured out already. If the coolant is getting into the exhaust it is either a seal or a crack in a housing. Does your oil look like it has any sign of water in it? Pull your spark plugs and see if the front plugs look any different from the rear.
In a fresh motor you are going to get some carbon build up pretty quick. If coolant is getting in you will see a pretty clean couple of plugs from one of the housings.
Is this a turbo?

I dont think its the coolent. I did add some though. The car doesnt see to be burning any oil. When I check the oil , I can gas on the dip stick. The oil isnt black or anything. After I idel for a few seconds a **** load a smoke comes out the tail pipe. THe temps are normal. I dont no what the hell this could be. I really hope its a tunning error. any suggestions. I change the leading plugs yesterday night and they were bad, but it still didnt help my problem. damn toco bell

You have a race car,race cars smoke.

To the basics: If you have smoke, something is burning. If it was just from being an overly rich mixture, the smoke would be black. If it was oil it would be gray, coolant= white.
If coolant enters the exhaust the O2 sensor will get an inaccurate air/fuel reading. It will compensate by injecting more fuel. If you don't have the cats on you will smell more fuel also.
You said you changed the leading plugs because they were bad. What did they look like. Also is this a turbo?

its a 93 with single t-78.

dingleberry

Street ported? BIG?

It will smoke......a little

93redFD

all 93's are twin turbo, mine has a single t-78 . Oil is white with blue tint. I can see the blue tint, but I when i just cut my car off, in the light It was black. Im going to check it out tommorow to be sure. What did the plugs look like?? (****) cracks, black and looked like they have never been change before!! Im going to take it to a tunner to see if he can striaghten things out for me. he is going to clean up the idle for me,plus hes fixing some electrical probs Im having.

Do you have all the smog **** taken off? If you don't leave a vent open for crankcase pressure, they will smoke like that.

nimrodTT

Yeah make sure you have some kind of a PCV on it. And you might want to try smelling the smoke, you should be able to tell what it is right away.

93redFD

smell it?? well the olny thing im smelling is gas!! The smoke is blue.I check the oil has about 120 miles on it, and is only one x from full. The iol isnt black or anything. If it was the turbo then it would smoke like hell when boosted. The car only doesnt when Ideling for 10sec, then a **** load a blue smoke comes out the exhaust. BIG STREETPORT, i know it will smoke but not like this. i figured out if I rev it 2500 rpms at redlight no smoke comes out I just added like 6-7 gals of gas and didnt use any 2 stroke oil. I was hopung that it was my problem but it still smokes like hell. The car doesnt smoke at all when i go in boost. I really hope its not anything serious. Im having a tuner to clean up the idle saturday. i guess we'll have to see from there. wish me luch everybody.. any suggestions are highly apreciated.
thanks yall..

So there's gas in your oil? It's gotta be either an oil seal or some kind of improperly routed vacuum line. Since the engine is smoking, and you say the smoke is blue, and you said the plugs were black; I'll conclude it's a bad oil seal.

Scalliwag

If this engine was just broke in you can change the oil and see if it starts getting gas in it again. Maybe it is just from flooding early on or something.

If you are getting blue smoke while idling your turbo is the likely culprit ... over oiling, restricted drain line, crankcase pressuring up, or rear turbo seal is shot (not really a seal, more like a bushing). It doesn't take much oil to do this. When my turbo seal went I pulled the turbo and found no obvious oil at the turbine or dp. Pull the turbine housing off the turbo and you could easily see the oil that was leaking through to the turbine.

White smoke is a killer, o-rings or a cracked housing . The starter to this thread mentioned a builder that I have heard horror stories about, including a close friend of mine. It is possible to startup a new motor and cook the o-rings if you don't get a good initial fill of coolant, hot spots. Don't know what else to say.

I had a clogged cat fugg up some new seals pretty bad. Damn, that was a lesson I never want again.

Felix Wankel

All you have to do is go look at the oil filler neck and see if anything is vented. Something should be. Either the neck or the center housing.

Check your injector for leak or "oring" injector...

93redFD

my oil filler neck is vented at the top.WhEN i first saw it I thought something was sopposed to go there. Is something soppose to go there???at

93redFD

would a compression chek tell me anything?? or is that just will apex seals??

KillerFD

any luck finding out what s going on . i have a very similar problem , same variables new engine yadayada ??????????????????????

93redFD

yes, i found out why. after the haltech was installed the oil pump or something that has to do with the oil pump still works. Instead of measuring the oil it just dumps a **** load. To stop the problem either get oil block of plates or a hight flow cat. Im going with the block off plates. If somebody will clear this up becuase its hard for me to explain. I was only interested in how to stop blue smoke coming out the tail pipe. I was also premixing the gas. the car is pulling about 18-19 in vacume. I dont think its the engine, but it could be. i was not pleased with my service from the guy. i drove 360 miles for him to work 30min total on my car. Afetr buying the car from him 3 weeks ago, he charged me 75 bucks for him to put the wideband on it. the cd player, dome light, guage dimmer(I can barly see the guages) still arnt working. When he put the motor in he burned a wire. All the electrical **** doesnt work very good. What pisses me off the most is that i had to drive 360 miles there and 360 miles back WITHOUT A ******* RADIO!!!! boring boring... and also got a damn speeding ticket, 83 in a 55mph( it was a construction area to) so I offered the cop a donut, he takes it, he still gives me a ticket for speeding( 77 in a 70).. he didnt right down that i didnt have prof of insurance or it was a contruction area nor I was going 83 sorry to get off subject..

SPZ510

Glad to hear your smoking has stopped. Why would you start premixing and not remove the OMP? Does it smoke at all now? What ratio are you using. I'm running about 1.4oz oil/gal of gas, and I have no smoke at all. Wondering if that's too lean. I was running 3.5oz/5gal.

93redFD

no, let me refrase it!! The car is still smoking. Some of the blue smoke it becuase the omp is not metering the oil and it just dumps a **** load. I didnt know that it was still there. Blue smoke is also becuase i was premixing. Do I have to buy block off plates or do i remove the opm???
