My car sits alot because its not my daily driver and for a while now when i first start it i get a little bit of gray smoke when the car is first started. However the smoke only comes out if i admediately rev the motor right after turning the car on. The amount of grey smoke is very small. What could be causing this? I have a feeling its just because of the cold weather and the car sitting??? you guys have any idea is it anything to be concerned with???

Don't immediately rev the motor! :mad: That's the worst thing you can do for it.

white smoke: oil or coolant
blue smoke: coolant
black smoke: unburt fuel
gray smoke: condensation in exhaust

If the smoke is more white/blue than anything it could be the valve seals weakening with age. If it's more gray, it's probably just fuel or condensation and nothing to worry about.

Yeah, believe it or not, if you daily drive a car for a long time (in my case, almost two years) and then it sits for awhile for body work (about a week or so, minimal movement) I was getting CEL's up the wazoo.

Apparently its a common thing when I guess your a big 'aggressive' with a car and then it sits and the body shop drives it like a granny. After awhile, it worked itself out though. Drive it around for like 15-30 minutes and the problem should go away.

Sounds normal. I would start it at least once a week let it idle for at least 15 -30 minutes get all the fluids up to temp. Take the old girl out for a spin. Sure you use all 6 gear 5 fwd 1reverse. What for oil leaks if you leave her sit for extend periods of time. I have seen seals or other thing dry out or deteriorate after long periods of not being used.

i usually change my oil and gas if it's sitten for a little bit over a week. Just for the safe measure.

and yeah, don't rev it when the engine is cold.

From my experience:

Blue smoke = Burning oil
White smoke = Coolent or condensation if cold

I wouldn't worry unless the smoke is light blue color. When the engine is cold the ECU adds more fuel so when you rev the engine you get unburned fuel = black smoke.

I heard that idling a car for long period of time is bad especially when the engine is cold. The oil pressure is low. The emissions are horrible. And then when you start driving, the tranny is cold but the engine is hot.

how do you warm up your tranny? :laugh:

it's bad too turn on the engine, cause it gets used.;) but we have to turn it on to drive it, right?

its' better to warm the engine up so nothing goes wrong with it inside and I'm sure it helps on the life of the engine, pistones, seals, etc...

Maybe I should explain more. Just because the engine is warm doesn't mean you can drop a clutch at 6000 RPM's.

Actually 60% of engine wear occurs during the first couple minutes of operation. Those who are really concerened about not damaging anything should use a pressuried oil injection when starting the car.

Here's current school of thought is warm up the engine.

Let the car idle for 30 secs to a minute.
Gently drive the car until it is warm (< 3000 rpms)

thats' what i thought you meant.

you do have to drive the car gently until the shifter goes into gears smoothly.

Don't immediately rev the motor! :mad: That's the worst thing you can do for it.

white smoke: oil or coolant
blue smoke: coolant
black smoke: unburt fuel
gray smoke: condensation in exhaust

If the smoke is more white/blue than anything it could be the valve seals weakening with age. If it's more gray, it's probably just fuel or condensation and nothing to worry about.
