i have a 91 SE accord just brought a new engine for it and fo rsome reason in the morning s when i start my car smoke comes out of the exhuast like crazy but the thing is it only does it in the morning not when im going home from school or anything, anyone knows what the problem is? i checked the oil seems fine.

 

probably condensation in the exhaust burning off.

when its colder outside, and you have condensation in your exhaust...when that heats up, its like breathing in cold air, just more, hotter, moist air

 

Sounds like condensation as mentioned.

But just to make sure... what's the color, what does it smell like (while standing near it wave a cupped hand through it and then sniff your hand), and does it end right when the engine warms up a little?

Also, what's the temperature been where you live in the morning?

 

smoke smells like something is burnign and its pretty cold in the morning maybe in teh 40's and yea it stops when my car is warmed up.

 

but the thing is its been cold for a while and it never happend like this it just started recently like 2 weeks ago.

 

Does this "smoke" hang around and get blown away? Or does it disappear pretty quickly.
We've got to determine the Steam/Smoke thing...

P

 

like it will come out for a couple of minutes maybe 5 minutes max and it goes away.

 

is it a blue/grey smoke?

smoke only in the morning may indicate worn valve seals.

The burning odor, smells a little like burning oil, or sweet like antifreeze?

I suppose, but more likely because it is just a small leak, and when the car sits overnight the oil slowly drips into the cylinder. When you start the car the next morning there's a small "puddle" in the cylinder and it gets burned off at startup. Throughout the day the oil doesn't drip/leak enough into the cylinder to be noticable when you start the car again. And since you mentioned it, perhaps the seal does expand some once warmed up making it leak less.

The nightly "puddling" & burn off is what was happening with the 305 that was in my truck when I bought it. Once I pulled the heads I there was some serious buildup from the burn off on the piston surfaces in the leaky cylinders.

 

should i be worried? how do i fix this?

these are all just possibilities.


what he meant by "is the smoke hanging around or dissipate quickly" is..

1. when it smokes, does the smoke, hang threre, blow down the road and such? and you can see it for a good amount of time.

2. or does it come out of the tailpipe, and then just disappear real quickly?

if its number 2, its probably condesation producing STEAM, which is not a problem.

if its number 1, then something is most likely burning

 

Check you oil level, if it is low, then your problem could be that you are burning oil, which as mentioned by notoriusB could be due to a few reasons.

 

it is def hanging there hte wind takes it down the street so something is obviously burning... shuld i get this fixed or i shouldnt worry bout it

 

bump so P can answer

oil or coolant are probably burning

color of the smoke, and smell helps.

the two have some pretty distinguishable smells

 

If it's a white smoke and has a sweet odor, it's possible you're burning Antifreeze from an internal engine leak which is allowing coolant into the Combustion Chamber.
If it's grey smoke and has the characteristic burning oil smell, you've started injesting engine oil into the Combustion Chamber.

The first condition can be verified (or eliminated) by a protracted Cooling System Pressure Test. You pump 18psi of air into the cooling system. If the vehicle holds 18psi indefinately, you're ok. If it doesn't, you've a system leak somewhere; and it will show it's ugly face somewhere. Either on the ground under the engine somewhere, or in the crankcase. If the second, the engine has to be yanked and inspected with the proper course of action determined.

The second condition could be caused by your piston rings having stuck in their respective lands and have lost tension with the Cylinder Walls. Try this; it's cheap and doesn't involve tearing anything apart.

Purchase either a can of SeaFoam or GM Top Engine Cleaner (PN# 1050002). remove all four spark plugs and pour equal amounts into each combustion chamber and let sit for at least three hours.

Go get a coffee
Entertain the GF or significant other
Go get a beer, anything - just go away for three hours.

Cycle the engine several times to evacuate the excess cleaner and reinstall the plugs. Roll the car outside and start the car. You're going to enjoy a re-enactment of a WW2 Destroyer's putting a smoke screen down (that's why I suggested putting the car outside) so get ready for the Fire Dept etc.

What you've most likely got is the piston rings have gummed up in their lands and have stopped conforming to the cylinders. This will free them up.
