hi guys my 93 wrx has recently started smoking on cloads of white smoke i have checked if there is oil in water there is not also checked for overheating none of that either also check if im losing coolant and im not so im confused she struggles to start and when she does she is idling eraticly just changed plugs and coils still the same any help guys

 

white smoke is normally a blown turbo

 

would that cause the eratic idle and struggle to start

 

could be the maf aswell mate but it does sound like your turbo is on the way out.

 

how do i check the maf?

 

there was a similar thread a while back that i asked this question.

Why does white smoke signify blown turbo? Surely its blue smoke?

 

Take it out and clean it with electic contact cleaner (halfrauds sells it) put it back in and see if its better. Not sure on subarus if its worth risking??? But unplug it while idleing, if nothing happens then the maf is dead, if the engine gets worse struggles to idle more or runs even rougher then the maf wont be the problem.

 

my turbo was on its way out it blew white smoke out not blue clouds of it to the extent that i got pulled oil seals had gone so sent the turbo off for a full rebuild fine after that

 

Not nice. Its not that i dont believe people, was just intrigued as to the cause of the white smoke? Whats burning, evaporating ect when a turbo dies?

 

willl chexk the maf tomoz peeps

hi guys rite just a quick update i had the car compression tested today and all was fine so i can assume this is not head gasket the car fires and somtimes starts but only when u tap the throttle and then it starts idles about 300-400rpm and thens splutters and dies help guys im realy strugling with this

 

it will do if your turbos fooked address that problem first

 

Check the turbo as suggested already AND the Idle Control valve and MAF sensor.

 

as i thought this all started after i got white smoke so you guys suggest turbo then well im gonna look for one and let u no also i have chcked the maff i am unsure how to check /find the the idle control valve

 

how will it cause probles on idle as turbo dont spin on idle ?

 

Sounds to me like you bought contaminated fuel ? ... Has this started after a recent fill ?

 

dosnt matter it will pour white smoke out anyway look for another one it will run rubbish with a fooked turbo or get it refurbished

 

dont think so it wudnt run on all cylinders with contaminated fuel as i have experienced this

 

to be honest guys i havant filled up since i have owned car and it was fine untill turbo went pop i have only had it 2 weeks and she aint on the road atm as needs a gearbox

i did a sprint day a few months back and after a few fast corners and a bit of stick. mine started to smoke like this everyone said head gaskets blown, but it went back to good old thwaites at warwick who knew exactly what is was, turned out it just needed an oil catch tank as oil couldnt get back quick enough,, seems like it was white smoke but if you look closley you could see a tinge of blue in it and smell it too
