hello everyone for years my car has smoked after its been sitting for a day or two then diven hard had it for years with no loss of power but now im selling and need it sorted i opened the bonnet today and the white smoke seems to be coming from under the heat sheild of the turbo any help please like i sed ive had it for years will sometimes smoke and some times i can go for a 100 mile run and nothing its a 98 s reg uk turbo wagon nearly stock wit 55k on clock

 

Do you have a exhaust leak, mine is leaking where the turbo bolts to the up pipe and the "smoke" comes out from the scoop! But mine sounds like a tractor. How thick is the smoke ?

 

i have no exhaust leak and mine sounds like new the smoke is fine enough to get your head in there with out choking

 

Does it smell like burnt oil?, if it does have a look at the bottom of the drivers side cam covers...chances are the cam cover is dripping oil into the exhaust headers/up pipe which looks like the smoke comes from the turbo and out of the scoop

 

it can smell like burning oil yes the smoke looks more like steam

 

just red on a few other forums that due to the smoke being white it could be coolant somewhere dripping onto the exhaust

 

Pretty sure if it's coolant you would know by the smell. Hot coolant smell is obvious.

 

rocker cover gasket caused mine

 

it is very smelly and the smoke is pure white

 

any drop in coolant levels then?

 

will check tmoz when its stoped raining it only smoke once its warmed up then i turn engine off wait for it to stop go do a 60 mile drive and nothing

 

white is usually water/coolant and blue oil related. you do have a water feed to your turbo so check that for leaks also.

 

but why would it just do it once a hard boost or warmed up then nothing for rest of day or day after

 

maybe water seeps out when cold but it seals when hot as metal expands? who knows bud these things can be hard to diagnose. if you had access to ramps it would be easier to see whats going on down there. park the car over a flat cardboard box over night and see if there is any leaks or spills in the morning. if not start the car and let it tick over for 10 mins then reverse off the cardboard and have a look again.

 

ive done that in my dry garage and nothing lol

 

gona take the heat shield off tomz see if anything is there

 

yeah meant to say take off the undertray or you wont see any drips lol.

 

its ok i no what you ment i did it with no undertray

 

is the shield easy to remove is it just the bolt you see on top
