VW 1.9 TDI after total engine and turbo repair burns oil

Why would a turbo burn oil?

If the turbocharger is losing engine oil via the intake or exhaust gas port, this usually means the pressure equilibrium is impaired due to problems with the oil/gas return line. Reasons for oil leakage: Blocked, kinked, constricted or carbonised return line. Oil level too high.

Do turbo engines burn more oil?

Turbocharged engines will require more frequent oil changes and fresh spark plugs, though turbo engines typically don’t require additional service compared to naturally aspirated engines.

Why does TDI burn oil?

You likely have bad valve seals or bad piston rings. That means oil is getting past these seals and being burned inside the engine. The act of burning oil itself isn’t typically a problem in your car, but you may notice a bluish-grey smoke coming from the exhaust if your engine is burning enough oil.

How do you know if your turbo is burning oil?

Oil can get into your exhaust if your turbo unit develops cracks, or damage to its internal seals. The extra oil will burn off in a blue or grey hue. You’re more likely to see these heavy fumes when using the turbocharger. Rev your engine and see if excessive smoke is emitted.

Do VW turbos burn oil?

German made cars like VWs do have somewhat of a bad reputation for burning a lot of oil. VWs with 2-liter turbocharged engines seem to consume a lot of oil but there may be other contributing factors to this as well. With the use of more synthetic oils, cars are getting a lot more miles in between oil changes.

How do you fix an engine that burns oil?

Number two okay um you might have to replace your pcv valve now basically a pcv valve that is faulty can cause a problem uh because it controls.

Is synthetic oil better for turbocharged engines?

“With its superior resistance to deterioration, AAA’s findings indicate that synthetic oil is particularly beneficial to newer vehicles with turbocharged engines and for vehicles that frequently drive in stop-and-go traffic, tow heavy loads or operate in extreme hot or cold conditions.”

How do I know if my turbo seal is leaking?

If there is positive pressure coming from the boost and the exhaust side of the turbo. It will not leak. If there is excessive crankcase pressure coming up through the turbo.

How do I know if my diesel turbo is bad?

Five Signs of Turbocharger Failure

  1. Sluggish Acceleration. As the turbocharger is designed to provide extra power to the engine, when working correctly, acceleration should feel snappy. …
  2. Guzzling Oil. …
  3. Increased Exhaust Emissions. …
  4. Engine Management Light/Check Engine Light. …
  5. Whining Noises.

How do I stop my turbo from smoking?

Number one your scavenge pump is off at this point if you have a low mouth. So it's not pumping the oil out. Number two the bearing is not taking up all of that oil and using it and getting rid of it.

How does a turbo get oil?

The turbocharger bearing system is lubricated by oil from the engine. The oil is fed under pressure into the bearing housing, through to the journal bearings and thrust system. The oil also acts as a coolant taking away heat generated by the turbine.

Can a bad turbo make a car smoke?

3) Excessive exhaust smoke

Excessive smoke is a symptom of a defective turbo — specifically a crack in the turbo housing — causing oil to leak into the exhaust system and dramatically increase smoke production. If you run into this problem, you should consult your mechanic about your turbo immediately.

Can turbo cause crankcase pressure?

The intake manifold is under pressure during most running conditions when an engine is turbocharged. The gas and oil bypassing the rings are still present, and the pressure generated by the turbocharger can increase crankcase pressures.

How do you reduce crankcase pressure?

Crankcase pressure can be prevented by protecting the piston rings. With a cold start, no oil film is yet present on the moving parts. The chance of metal-to-metal contact increases, so that the piston rings wear faster. This can be prevented with the Lindemann Engine Performance Treatment.

Can a faulty turbo cause Blowby?

Can Turbo Cause Blowby? Nevertheless, if the seals are out in the turbo, the boost pressure or exhaust gases from the turbo can enter the oil return to the crankcase, causing blow-bys.
