White smoke coming out when ripping it something

[Mr EG]

Dunno if it's white or grey, but is this a problem?

[denrie]

most likely needs rebuilding, how many ks has the car done? and what engine is it? piston rings might be gone

[MWAKU]

uhhhhh rebuild?

if its blue ur in trouble

white isn't bad if i remember

[dsee2]

when moving off in first gear? or when hitting vtec?

if lots of smoke when moving off in first gear, you need to get some engine work done.. valve stems and stuff..

a puff of smoke when hitting vtec: it's normal. just running rich as air-fuel ratio jumps higher

[damienm]

could be that he has too much oil

[4age8u]

or rings are fu**** oil leaking? how old is your oil? hows ur headgasket? leak?

[whyte]

hope your rings aren't fked
get a compression test done to make sure.
could also be excess oil burning if you just recently serviced the car and put abit too much oil in lol

[tiksie]

I'm assuming this is when you hit vtec.

If so.

It's normal.

White smoke: White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area. The cylinder is where the fuel and air mixture are being compressed and burned. Any amount of antifreeze that enters this area will produce a white steam that will be present at the tailpipe area.

If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.

How did antifreeze get in the oil or cylinder in the first place? The engine probably overheated and a head gasket failed due to excessive heat, thus allowing antifreeze to enter the cylinder (Where it is not meant to be).

Blue Smoke: Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Black Smoke: Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor.

How did the fuel get into the cylinder in the first place? Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil as in the white smoke example to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil. Call your mechanic and advise him of what you have found.

I hope this helps you determine what could be causing your engine smoke, and the possible reasons behind the smoke.

hope this helps

Urgh ... OP i think you should at least come in and confirm one of these problems !

[WATAJK]

TIme to go get it checked out but i fink ur looking @ a rebuild mate

[migoreng]

i get white/blue smoke sometimes as well...
oil can burn white/blue i read somewhere.

it's weird. i think it's oil going up the pcv valve but i can't be stuffed getting an oil catch can atm.

also i don't loose coolant so i'm not burning coolant.

just check your coolant and oil levels...my car is a prelude vti-r with 200k km and they burn oil naturally...i have to top up around 250ml every 1000km

edit: and i think you may have a civic that puffs out weird white smoke like i mentioned in this thread:

White smoke is common when you hit VTEC dw about it. Just check your coolant ain't too high.
