I have a 2000 mr2 spyder thats running ruff , smoking havey white smoke and has oil in the coolent. ant thoughts?

I had the same problem. My check engine light was on. Took it to the dealer and they checked the code. It was the throttle control motor failure. The good news is I got the wiring wet and that seem to be the problem. They reset the check engine light and it runs fine now. Bad news is if I had to get the motor replaced they said it would be about $1300.00 I hope things work out for you.

SOURCE: White smoke exhaust

White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....

white smoke is is antifreeze problem cracked head.. head gasket.. intake gasket .. pull yout spark plugs check color of plugs if one looks real clean compared to the rest that will give a point where the problem is

Hi Ross,

As a rule:

• Black Smoke = Unburnt Fuel, incomplete combustion, bad mix
• Blue Smoke = Burning Oil
• White Smoke = Water Vapor, Water getting where it shouldn't be.

White smoke is common in cold weather when you first start your vehicle. It's from condensation. But it should stop as the engine warms up. If it doesn't, the moisture is from another source.

Questions:

1. Are the smoke episodes accompanied by a loss of power?
2. Was your coolant level low before you changed the coolant?
3. Did it overheat? Badly?
   

I'm leaning toward a partial failure of the head gasket. Here is some info, things to look for and tests to confirm.

Symptoms:

• Uncontained compression in one or more cylinders = lack of power
  
• Coolant seeping into cylinders through the gasket breach creates white smoke
• Oil seeping into cylinders creates blue smoke
  

Things to look for:

• Coolant levels low. As the coolant is burned off, you'll notice the levels are lower
• Oil in the coolant. If oil is present in the radiator, it's coming from the engine. Another indicator of a failed head gasket. Only a confirmation though, lack of oil does not rule out the possibility.
• Water in the oil. Pull the oil dipstick. Is it milky and frothy, like it's been whipped? If so coolant is getting into the oil. Again, an indicator, not a confirmation of a blown head gasket.
• Is the oil level dropping?
  

The quickest, easiest and (most importantly) cheapest confirmation of this is to run a compression test on each cylinder. I'm surprised your mechanic didn't suggest it.

The test should show high and fairly close compression (100psi or more) on all cylinders. If any of them are significantly lower, something is allowing the gasses to escape. Since piston ring failures would produce blue smoke, not white, that leaves the head gasket.

If you feel comfortable doing it yourself, testers are available at any auto parts store for under $30.00. If you don't, any shop can do it in under half an hour.

All this is to pin point the problem. Then you know what you are dealing with.

Comment me back with your findings.
Mike

SOURCE: 4-3 vortec gas in my oil 1994 s10 blazer . vehicle was running

it doesnt take long to ruin the engine diluting the oil with gas - i dont know how i dodged that bullet, mine was leaking -gas into the oil- new spider is only the beginning of the care and feeding of the unpowered poppit spider motor- regular bottles of injector cleaner will keep them poppits clean, otherwise fuel deposits mess up the quantity and pattern of the fuel spray quickly from new- i had long suspected the new spider i installed was faulty, (Sorensen), but it was just quickly plugged by fuel deposits-as i understand it, the additives often in gas like to hook up in the poppits- my 1994 4.3 S10 kicks **** now, runs like it did when i bought it 5 yrs. ago, smooth like its supposed to, i was chasing the piggy/miss for two yrs, bottles of injector cleaner didnt help, it needed a heavier mix of cleaner
- it couldnt hardly get itself and a little aluminum boat out of a easy boat ramp, what broke free the deposits was doubling up on the amount of injector cleaner i dumped in the tank, when a person takes a clogged injected vehicle to a shop they hook up a pressurized system to it ,and disable the fuel pump -shop air system is better than aerosol can system, force the engine to run on a <10%> cleaner/gas mix for 20 minutes, guess i did get lucky with results from the cleaner addtive, cuz the real fix is find a shop that does the 10% cleaner 15-20 minute pressure wash of the injectors, and it should be done at least every year- mines running so good now, ill not see a lot of results from the pro cleaning i'm scheduled for tomorrow morning - hate to cancel tho- these unpowered poppits are very finicky - i did reuse my plemun half shell gasket, it has the red rubber line on it and it was still live so i reused it
