just changed my dump valve toa recirculating one and at to change my lambda sensor has poor idle all seems ok now but i have blue smoke when my cars warm on ideaand bit when im backing of while driving what can it be and is there anything to check ??? power etc seems to be ok just burning oil somewhere

 

rings on way out??????????????????

 

smoke on overrun usually indicates turbo trouble

 

Blue smoke is usually a sign of turbo on it's way out

 

just a thought,but as it only started after fitting a recirc vale could it be oil in the intercooler or pipework from engine breather system?

 

im gonna clean allthese today just see if makes a diffrance

 

would say turbo is on its way as well, you would be able to smell if you was burning oil.

 

I wouldn't associate blue smoke with the turbo - white smoke yes

 

take the inter cooler off, & check the turbine housing to see if there is any oil there.

if not, it could easyerlly be the rings

 

cheers people i noticed b4on tick over some white smoke coming from the turbo area just has i blipped the thottle?? do u think this indercates turbo leaking some where???

 

whats millage on your car what year ,

if the the turbo is a td04 (96 wrx on) i would say the bearing is worn making the seals oval which causes the smoke, good news they are cheap to pick up second hand and easy to change

 

its 99 uk model with 37k miles on the clock tdo5 upgrade

 

any ideas?

 

Doesn't white smoke usually mean piston problems????

Or too much gas for the available traction!

 

no it is turbo

 

so the smoke coming from the turbo area and blue smoke from tailpipe big indercation my turbo seals have gone????

 

??

 

rings on way out for the 2nd time

 

i agree with scoobyman95

 

blue smoke will be engine related,ring etc, white smoke will be turbo related you have to make sure your car is really warm as it will smoke when it is cold so run it then park a blip the throttle then look to see what the smoke is.also if it is turbo when it comes into boost it will smoke like a bugger you wouldn't see anything but smoke??

 

I had both blue and white smoke, and a general smell of oil. Even when warm.

Do you have a catch-can? I've removed mine and all smoke is gone. And the smell. New rings recently, too.

However, still using more oil than I'm happy with so inclonclisive at mo. But if you have a catch-can, either clean out the whole induction system and/or get rid of the bloody thing and just vent straight to atmosphere.

You can refit it at anytime of course, but they clog up with ****e very easiliy in cold weather. It will, at least, remove one of the possible causes.

Does your car run okay otherwise? Mine is perfect now - just using too much oil (2.5l conversion) for comfort.
