hi all need some help? went to look at a 2005 renault scenic 1.5 dci, took for a drive and seemed ok, left the engine running went around the back of car and see white somke comming out of it? is it ok or is it fcuked, its only got 28k onthe clock.

many thanks
 
It could be a number of things mate.

Too much oil in the engine wil cause smoke - not serious.
Water (coolant) leaking into the engine will cause smoke - serious.
Worn bits and bobs inside the engine can cause it - could be serious but not always.

I'm not a mechanic, so ignore me. :)

But I recently had loads of smoke coming from my exhaust, it turned out to be too much oil.

Are you sure it was white and and not blue-ish?

cheers for getting back so fast. it is defo white and little bits of oil was comming out also and that was when it was only ticking over?
 
Best asking one of the mechanics mate, Smirnoff knows his stuff.
 
I think if it was burning oil m8 they would be loads of smoke like the car was on fire constant white smoke and dripping oil doesnt sound good to me I would deffo get it checked out better safe then sorry
 
Just found this on wikianswers m8 doesnt sound good

( oil getting by the rings causes white smoke and oil dripping out of the tailpipe. )
 
thanks i think i will give it a miss then, just hope i get my 100 deposit back.
 
sounds like head gasket gone to me , i'm sure smirnoff be around later for a second opinion
 
Hi
First again you sure its white smoke
Cos oil burning gives black/blue smoke
If water is leaking in somewhere then you get white smoke
Cracked head or gaskit prob springs to mind
But if someone has put wrong fuel in
then the cleaning of the tank will cause white smoke 4 a while
But im only a novice at this best wait for the people in the know
 
i just scrapped my 1998 Scenic for a similar problem. Lots of white smoke out of the back - head gasket had gone. By the time i arrived at the garage it was blue smoke too - definite sign of oil/water mixed - proper stuffed.

i got £50 scrap - but mine was old and knackered. ho hum.
 
hi, mate, i believe your piston rings are gone and your valve stem seals, hence engine f*cked...

Now i aint a mechanic
But broken rings caused black smoke i thought
Well thats what happened to my first car
To check that remove spark plugs they will be black at spark end
Where the oil is seeping in to the piston
but that dont make sense to me but as i said i aint a mech

Edit
Question is this car petrol or dev?
Oh and the above post sounds the most likely

Ok white smoke is water(steam), in cold weather lots of cars can smoke, if it's been standing and or had short runs the exhaust could have lots of water in it, you need to give it a long run and see then.
Are you sure it was oil dripping? As water can also drip out the exhaust and can be black and look like oil, this also can be normal.
I'm not saying there isn't a problem just that it could be normal.
One thing I remember from collage(a long time ago) is that for every gallon of fuel you use, the engine producess a gallon of water.

Me again
Now as said its water for sure then
As for the colour cooling systems rust( so look like oil)
If it was oil and water then they would separate
Which is very noticeable
Now too the exhaust which always has water in it
You gonna have to find out if its been standing unused for a while
As said burning fuel creates water normally in exhaust
Bad cold weather like we had wouldnt have helped
Sorry but only way youll know for sure is take it on a very long run
Boy racer springs to mind!!!!
Just watch out you dont end up with blue smoke or bye bye car

Sort of correct but its not at the same time


Too much oil in the engine wil cause smoke - Serious as it can cause piston slap
Water (coolant) leaking into the engine will cause smoke - serious.


However


White smoke is normal from condisation in the exhust burning off since you first started it in the morning -- Not serious


Start of the head gasket going (you can comfirm this by looking under the oil cap if there is a load of white gunk) -- Serious Get it to a garage asap

Oil burning emmits blue smoke -- usually piston rings going cause this serious ovbouslly

If it was warming up from sitting a white then dont worrie about it (Or its its a relly cold day as well)

If it looks like this :

Then its defo head gasket ;)


Blue smoke is oil if it looks like this get it to a shop :

Black smoke is running rich

Hope this helps


Black smoke : Running rich (Wont kill it stight away but get it check)

Blue smoke : Burning oil, Usually piston rings

White smoke : burning coolent, Usually headgasket
