white smoke problem

[adamclio182]

hi everytime my car hits about 5k rpm in second i get alot of smoke come from the exhaust and continues into 3rd gear. never does it when driving slow its only when i put my foot down in 2nd. been doing it for a while now and now my emissions light has come on. any ideas???

is this in cold conditions? have you checked the fluid levels?could be headgasket issue maybe. check coolant levels.

 

[adamclio182]

no its usually warmed up and can be at any point in the day. oil levels etc are fine. would doing a oil change make any difference or is it likely to be something more?

there's only 3 kinds of smoke that your car can have: black, blue, or white. White smoke is water vapour, and the most common cause as stated above is a blown headgasket. Park your car and have someone rev it up while you look at the exhaust fumes.

cheers. would it smoke all the time or at a set rev point?

Good to see another staffs user! How often do you go over 5k rpm? Sometimes the smoke seen can be mistaken for water vapour from water lying in the exhaust that hasnt evaporated. Mine does it sometimes!

 

[adamclio182]

not often tbh. only happens a few times. just making sure got no serious problems

Sounds like water lying in the exhaust which is being burnt off when 'putting yr foot down' but no harm getting it checked if its bugging you.

just annoying to look in my mirror to see white smoke blowing everywhere. my mate dont like being behind me either when it happens lol. wouldnt be over fuelling or anything like that would it? or be anything to do with cat?

Did a half hour journey in my old 182 when I first bought it, then booted it and got a cloud. Was water from them washing it.

 

[adamclio182]

havent cleaned the car in bout 2 weeks and car was bone dry. been doing it when the weather was better earlier in the last couple months. getting quite poor mpg so didnt know if it was related to this

 

[Mike_182]

Might be fuel then?! If it's running that rich I suppose it could do, but I really don't think it could be.

Mine had plumes of white smoke and when it cleared the rear window was wet. My exhaust was full of water. Most of the time i drive it slow like a granny and time to time i open it up on the motorway.

 

[adamclio182]

got somebody who is going to read the ecu fault to see if its anything related. should know by end of week all going well
