Right guys n gals I've got a question for you.

Since FITP on the way home after stopping for my exhaust (derby area) on the motorway my
started smoking badly at some speed from the exhaust (standard) been out in it again to day and started doing it again miltek was fitted Friday. The only thing I have done different apart from the exhaust was after picking the exhaust up i was low on fuel so put some total in normally I use bp ultimate but I was that low I needed some could this be the reason for the smoking or could it be something else. There is no loss in power or anything abnormal apart from clouds of White smoke.

Can any body shine some light on this

have you put oil in the car???


sometimes putting too much oil in the car will kick out smoke,


putting too much oil in a car is baaadd

I topped up oil the morning of FITP I forgot about that but it was low

Go check the levels!

Just had a look it's high so I guess take some out would be a start

Was it a 'bluey white' smoke mate??

how high... remove your breather pipe and look how oily it is...

Not really sure rob as soon as I saw it I eased of the loud pedal

If it was, it would be oil mate, sounds like the likely cause...........

If its that high try and get some out

Just had a look at breather pipe and that's clean but it's a samco of the mountune if that makes a difference

have you used nicotine patches?

Worked on my car before use apply the patch to the K&N.

should hopefully stop smoking

take it to the garage mate i reckon your car is running rich on fuel.

It doesnt do it all the time jus when given some then when it smokes let it drop of a bit then stops for a bit and starts again

depending how high it was you could of blown something with the added pressure... make sure you remove some... im sure the oil pumps do have a pressure release valve though, it maybe coincidence.... depends on how much smoke your getting though

What can cause white smoke from the exhaust?
Here are the best answers compiled from our contributors

Answer 1

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling.

Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

Answer 2

If the exhaust billows white smoke for a few seconds when first starting the engine after it has been sitting for a while, such as overnight, and then runs normally, it could mean that the rubber valve stem seals have perished - especially if the vehicle is a few years old and has done over 60/70,000 miles.

Another clue is: does the exhaust smoke smell like fresh, rather than burnt oil.

Answer 3

After going nuts trying to figure out sporadic tailpipe smoke on my Nissan Maxima, with no other negative engine symptoms, I eventually stumbled upon a malfunctioning PCV valve. The ball-check wasn't fully seating, allowing small amounts of oil to sneak past and into the combustion chamber. A cheap and easy fix.

Answer 3

White smoke or semi white can be produced in several ways. One way is oil this is normally a whitish blue to blue smoke and has the apparent smell of oil being burned. Next could be antifreeze when it is being burned it has a sweet type of smell and tends to dissipate in the air rather quickly. Next is automatic transmission fluid which is normally found on automatic transmissions and its normally drawn into an engine thru a vacuum line via a defective transmission modulator valve or some other defective part. Transmission fluid is very apparent and billows out so bad that you can't see anything behind you. Last but not least another type of smoke that is not white but black is the presents of to much gas/fuel being burned in the engine. Hope This Helps, EzForJesus

PS the one good thing about transmission fluid being burned is it is an excellent way to clean the carbon out of an engine.

Answer 4

Black smoke is burning oil. Blue smoke is usually transmission fluid due to a leaking modulator valve in the older auto transmission. White smoke is due to water getting in to a cylinder from a bad gasket, cracked block or a cracked head.

Answer 5

cracked heads. Mine started misfiring, with new plugs. Smoke came out the exhaust.

Result, low compression in the cracked head. When car was cold it ran fine. After it got hot, the crack in the head would open up, hence, sputtering. I've had to replace 3 heads. Everytime I've had to have this done, I had to buy a whole new head gasket.

Answer 6

After extensive research I came to the conclusion that TOO much oil is also a main culprit for white smoke out of the exaust.

Answer 7

I changed the PVC valve, the breather and the air filter and it's good as new.

Answer 8

There are a lot of incorrect answers here... but for the most part, you can hold true to these:

Blue smoke is primarily from internal engine wear. If it's constant when the engine is on, then the rings etc are worn and need to be replaced. If it only is blue when the engine is cold or first started, the rings are worn but not gone completely. You get the oil seeping during the night and it burns off when the car is started in the morning.

Black smoke is a fuel/air mixture suggestion problems with injection or carburation. Cause of black smoke is due to running rich in the fuel air mix.

White smoke can and DOES come from coolant burn off in the oil due to a leaking or blown head gasket, cracked head etc.

If you aren't sure or you don't know what you're talking about, don't advise. Wrong advice can be more damaging than the actual problem.

Answer 9

White smoke is caused by engine coolant/Antifreeze being processed in the combustion chamber(s) of the engine.....ie burning, melting, frying, whatever....

Peirod....

I'll explain further.... This is automotive chemistry 101....

Oil of any automotive type burns blue.....

too much fuel issues burn black

not enough fuel issues burn grey

on a cold day you may see what appears to be white smoke from the exhaust that will disappear after the vehicles engine has warmed up to it's normal operating temp.. This is a normal reaction called condensation... condensation is the result of a small amount of water/dew being drawn into the exhaust usually collecting in the muffler and/or the catalytic converter and is caused by our friend mother nature..... like when you see your breath on a cold day...
