hi i have a 03 wrx which has just started to smoke a little it doesnt smoke when its started or ticking over to start with or even when im moving on boost but when i leave it standing for a few minutes or so it starts to smoke.It doesn't do it all the time just when i give it a bit and then stop and leave it tick over.Any ideas what the problem is?

 

any ideas anyone?

 

Well it would help if we knew where the smoke was coming from: out of the exhaust, from the engine?

 

exhaust mate

 

Could be valve stem oil seals, or rings.

 

i thort it would do it from cold start if it was rings or stem seals?

 

It would be worse from cold if the above had gone, what color smoke is it ? blue, white or black, dont confuse the the white and blue as they look simlar to the untrained eye.

 

Im pretty sure its white smoke

 

if its white smoke mate that means its water, dont panic it could be one of 2 things, first is the coolant is going through the system (head gasket gone) the second and the more probable one imho is its moisture in the exhaust, when you give the car a good spirited run it will heat the exhaust up to the point where the water will evapourate ie white smoke,
i hope this helps and good luck

 

i`m not absolutely sure on this but i belive unburnt oil can give off white smoke, ie oil that is leaking from the turbo on the xhaust side, yes its got hot and created smoke but it hasnt actually been burnt as in through the engine.

i doubt what addi has said above is correct in this case, ie the weather is very hot and you usually get condensation burn off for say 10 mins after cold start,

also i think stem seals does as you have described.

 

im sorry my mistake it must be blue because u can smell the oil,its not water

 

Turbo seal?

 

ahhh blue, it is hard to tell as its only a very slight tint of blue but blue is oil, after a hard run it may well be the turbo seals are on there way out the above post was the only 2 reasons i could think of for white smoke with the circumstances you gave

 

as above sometimes hard to tell if its blue or white, looks like turbo off , check intercooler for oil first.

 

ok thanks for the replies its looking like something to do with the turbo,if i give it a bit of a run and take a look around the turbo will there be any obvious signs or would it only smoke from out the exhaust?

 

There wont be much to see mate, pop it into a scoob specialist for them to have a look, remember looking is free

 

gona get it booked in tomorrow.thanks for the info everyone.

 

Specialist, NOT garage round the corner, NOT dealer

 

for the love of god listen to the above quote

where are you taking it .

 

not sure ive got a choice of subaru central,forresters,pole position and subaru donors near to me,where would you recommend near to wolverhampton?

 

had the intercooler off today and there is oil in the so im guessing it must be the turbo,there isnt anything else it could be is there before i source a new turbo?

 

you can buy turbo rebuild kits fairly cheaply nowadays might be worth looking into?

 

what turbo are you running mate ?

 

only a td04 was thinking of upgrading

 

if you upgrade you will need a remap fella, tdo4's are going for £50 on flea bay so its not too bad of a fix.

 

yeah i no not sure weather to just replace the turbo or upgrade turbo with sum pinks,up pipe,etc,the car has been mapped by scoobyclinic do you know if the ecu is now locked or can someone else map it,also what sort of price do you think it will be for them to remap now the ecutek license has been paid?

 

no idea mate, i always use duncan (racedynamix) give him a bell im sure he will be able to map it.

 

im pretty sure andy forrest will remap an ecu that is already ecutek lisenced but mapped by someone else starting at 280 quid

 

i think thats the route im gonna go down,having classics in the past it feels sluggish.Andy forrest is too far for me,where is duncan based ive read good reports from his remaps.

 

duncan will come to you, hes based down south , search for dynamix on here and his number will be on his post's,
