Check for blockages in the air filter system. replace the air filter. The only way that oil can get in to the turbo inlet hose is if the turbo is running in a vacuum and sucking oil fast the turbo seals Unless the turbo bearings are shot.

SOURCE: BLUE SMOKE FROM AUDI RS6 ON DE ACCELERATION AND

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.

How can you determine if your oil leak is coming from your turbo on a 2002 volvo s60


Do you have a external leak or does your engine oil drop but you can not see a leak. My S60 had a leak and it was from the return pipe from the turbo to the sump.You can remove the belly plate and look from the bottom at the back off the engine.You will see the return pipe at the bottom of the turbo. If it does not leak at the there the turbo might be worn and it is blowing the oil into the intake.To check remove the intake hose and check for excess oil in the intake system.

White smoke Audi 2.0 non turbo is this connected to excessive oil consumption is a 60k mile engine A4 reg 2001.


White smoke is usually coolant burning, but you say no loss of coolant, so must be oil burning. PCV is possible fault, especially since you say smoke is intermittent. Part itself should be cheap, less than $20. One your car I believe it is located in a pipe running from intake to valve cover.

Intercooler line floaded with oil


CHECK YOUR OIL LEVEL IN ENGINE INCASE OVER FILLED THIS WILL SUCK IT INTO ENGINE, IF OK CHECK YOUR ENGINE BREATHER TO SEE IF BLOCKED CAN CAUSE BACK PRESSURE IN ENGINE AND START BLOWING OIL SEALS AND GASKETS, AND THE 1ST TO GO IS THE TURBO SEALS, YOU CAN REMOVE AIR INTAKE PIPE TO TURBO AND CHECK FINS INSIDE TURBO WITH YOUR FINGERS TO SEE IF ANY MOVEMENT IN SHAFT. PLEASE DO THIS WITH ENGINE TURNED OFF :)

Exhaust giving off white smoke when parked up with engine running audi a4


White smoke is caused by engine oil being burnt. If your vehicle is turbo charged then it is most likely the turbo bushes that are worn, allowing oil to escape into the exhaust system. This can also be caused by worn piston rings but is unlikely on a vehicle of this age unless it has overheated badly in the past. To check turbo, remove main intake pipe from turbo. Check for excessive movement on impeller shaft in turbo by moving it up and down. To check piston rings carry out a compression test or if you have the equipment a cylinder leakage test will give you a better indication of cylinder condition. If the Turbo is at fault it will need to be reconditioned or replaced. Check oil feed pipe to turbo for blockage or restriction [common fault].

Audi A6 3.0 tdi Quattro 2005, glow plug light comes on, limp mode


16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

I have fault code 00575 intake manifold pressure on my audi a4 soft top were in engine is this component found


I assume it is a turbo diesel? Then:

Location of the sensor:
- in early cars is in the ECU, with vacuum pipe going from intake maniforld duct to the ECU
- later models on the air intake duct, with wiring going to the ECU.

The fault may often be caused by:

- air leaks in MAP sensor line to the ECU (early ones only) or any of the vacuum control line hoses. This normally due to perished/loose flexi pipes, etc).
- leaks in the air hoses going between turbo/engine/intercooler. Can be spotted by slight oil contamination at the point of leak.

Or it's variable vaine sticking (even intermittently) in the turbo due to contamination, preventing the turbo from performing according to the ECU demand, and hence being 'shut-off' by th ECU

So - check all vacum line for leaks, ensure turbo actuator is free to move, all air hoses are intact and secure, intercooler not leaking.

1991 toyota supra blue smoke from tail pipe when get of the gas


The intake valve guide seals are worn and are letting oil slip by under high engine vacuum--as when you let up on the gas. The only fix is to take the cylinder head off and replace the valve guide seals. This problem is pretty normal for an older car with high mileage. It will probably run just fine. Just keep checking the oil level and keep it topped up.
