It's your piston rings..

Maybe valve stick?

In colder weather its normal to have a little bit of white smoke from this shitty ethynol gas. Moisture settling in your exhaust system will cause some white smoke as well.

FYI guys.. When you burn oil it would be black smoke

boxeocampeon

sounds like either the rings or blown head

Lord Yod

How much smoke are we talking about here?

fryman

Correct me if I'm wrong but...

Black smoke = unburnt gas caused by a rich a/f ratio
white smoke = water
blueish white smoke = oil

I know it uses a different kind of oil but 2 cycle engines make blueish white smoke because of the oil being burnt.

itsnotfast

Your right.. Brain fart
Extreme black smoke can be oil

itsnotfast

At any rate man, check your compression white smoke can be slight moisture burning off or it could be a head gasket with a hairline crack in.

has the headgasket ever blown before?

Sounds to me like valve seals could be leaking just a lil bit. If you dont go through oil or water dont worry about it. My chevy truck does the same thing puff at startup then thats all

Sounds to me like your head gasket. They don't always "go" right away! I had a crx that did the same thing over about a month or so.....the seal on my head gasket was slowly going, and i did have to replace it.....that solved my problem. You don't have to have an engine to over head for it to go, it can just be age.

Check your dipstick. If you have a white residue sitting on top of your oil, it's water and that means head gasket.

Zector

just try a chemical test at the radiator..it tests for exhaust gases that are escaping through the headgasket and you will see if you have a headgasket leak...worked for diagnosing the head gakset on my del sol after it over heated for 2 days without me knowing lol and it started spitting out white smoke shortly after haha

You can have a blown headgasket and not have the coolant going into the cank case and oil in the rad. Depending on where the headgasket seal is broken it can simply be going into the exhaust system and burnung off. When it gets worse (and it will) it can cause serious problems if not taken care of. Im not saying you can't drive on it but I would say change the headgasket asap. I had an Integra that did this and it was almost unnoticable. The car eventually began to misfire at first start up until it burned the coolant off then it ran fine. Check your compression or tke the lid off of your radiatior and if its bubbling you need a head gasket.

just start your car up.
remove radiator cap.
if it start to shoot out like a gyser then you have a blown head gasket.

if it only does it when its cold, ITS NORMAL

Lord Yod

This is important.

Guys I apologize for not replying any sooner, I’ve been working long shifts.... but the smoke coming out from the tail is not a lot (not smoking like a chimney) it’s minor nut noticeable but then stops. Today I started her up and no freaking smoke but I still got some water dripping out from the tail pipe. I also noticed (should off check this sooner) what appears to be an oily substance in my radiator overflow.
Thanks

honestly...i just had the same problem. Check your valve seals on your cover. I am 100% you have oil in your spark plug place. i swapped heads and everything thinking my head was done. once i took it off and looked at my spark plugs, the threads were covered in oil. check that before you do anything drastic..

itsnotfast

Dude... some white smoke is normal with cold start. I wouldn't worry about it. Go to the dealership and start a brand new car it will do this as well. Unless its continuous white smoke it's nothing to worry about. If you are still worried take your spark plugs out and look at them if any of them is a yellowish brownish color its a bad headgasket. If not keep on driving.. its fine

tico

Dude its not really smoke. its more like steam. its actually a goo thing, its telling you that the engine has a good fuel ratio and your not having unburned fuel. its caused by temperature difference. hot exhaust gasses flowing through a cold exhaust pipe. nothing to be concerned about ur perfectly fine. the oxygen in the exhaust is getting cooled down and turning to steam.

could be early signs of a bhg. do a comp and leak down test. are you sure its white and not blue. also check your coolant and oil for mixing. check the inside of your oil cap for white sludge . and if its blue it coudl be rings and or valve guides. just ideas good luck

supra-n-civic

do not drive it if you have a bad head gasket. even though it may not be that bad. you need to do a leak down test and find out before it gets worse. if it starts mixing coolant and oil in your crank case(you may not see this is earlyer symtoms, you can and eventualy will spin a bearing. ive had alot of issues with this in my supra motors. ive had two 7mgtes with bhg and both spun bearings. until i finally built my motor with a stainless head gasket and arp head studs to aleviate the issue permenently
