Hi wite smoke from the exoust wen under compresion and then exalarate it is gone . have done the rings ,velve stem seals and turbo kit and stil smoking .

if the smoke is after you have been idling at lights for a few minutes , then it is valve stem seals gone hard or worn
if you are driving and accelerate hard as in passing then it will be worn big end bearings over loading the oil rings
turbos with oil seal problems will smoke all the time and if it seems to have no power , that could be from from leaking intercooler hoses, cracked intercooler or intercooler pipes or from faulty dump valve control actuator
check the viscosity of the oil in use as it may not be correct for the operating conditions or mileage of the engine.

Hi there,

This advice you received is correct.

Blue smoke emmitted from the tailpipe signifies the engine is burning oil.

Possibilities are:

• BAD RINGS - and engine with bad rings will not only burn oil, there will also be a significant loss in power, especially noticeable when driving up hill.
• BAD VALVE STEM SEALS - with this condition, blue smoke mainly appears during acceleration.
• Turbocharger - if your engine is fitted with a turbocharger, the seals on the turbo could be leaking.

In regards to the Bad rings and Bad valve stem seals, this may require some serious money, unless your vehicle is covered by a warranty.

For Bad rings, you will need to have a "wet compression test" done on your engine to determine if the rings are bad. Having these replaced will be expensive and in some cases, a replacement engine (with a warranty) may be an alternative option (or sell your vehicle and put your money towards another vehicle).

For Valve stem seals, I suggest only having the stem seals replaced (nothing else - don't let them talk you into any major work) to see if this cures the problem first. If blue smoke is still emitted from the exhaust, then you may be up for a major valve job, in which case you should again consider a replacement engine (with a warranty) or selling your vehicle.

Hope this helps...

Did you have the head reworked with the motor cause it sounds like the valve seals are gone and letting oil leak back down.

General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.

Smoke can be from rings worn out, cracked piston, valve guide seals if smokes at start up then stops, fueling issues if fuel is to rich but that smoke is usually black, also if head gasket is blown or head is cracked water burning turns into steam which looks like white smoke. This can also be why won't start just turns over.

This is either worn valve stem seals or worn out oil rings. Have someone follow you if the car smokes more as you release the throttle on deceleration it is most likely valve stem seal if it smokes more on acceleration it is worn oil piston rings. If the smoke is white you have a blown head gasket blue smoke means burning oil, black smoke means too rich (to much gas reaching motor)

Sounds like you need a new turbo, the turbo is lubed by engine oil and shaft seals leaking into the intake.

Hi , if you have had a turbo failure on this vehicle , just replacing the turbo will not cure the cause of blue smoke . depending how bad the seals had gone in the turbo you would need to replace , the complete exhaust system , the crankcase breater , air intake manifold , air charger but only if these items have been contaminated with oil , they would not be able to be cleaned out , hope this helps , regards mark

it may be the oil rings and not the compresion rings? or may just be the valve stem oil seals.
