The bearings and seals in the turbo are going bad, so oil is getting burned with the fuel.

2003 Volkswagen Jetta black smoke when going up the mountain


sounds like the turbo could be going bad, did you check air filter? Black smoke generally means your not getting enough air to burn fuel.

How to recognize if my turbo is causing blue smoke from the exhaust vs a blown head gasket. I don't have anti freeze mixed with my oil but it smoke coming out the exhaust when the car is running. ...


It's very simply to find out if the turbocharger is causing blue smoke from the exhaust vs a blown head gasket. So, remove the turbocharger's compressor inlet centre hose (from the aluminium side of the turbo). Then see if there's in plenty of oil coming out from the hose and from the turbo. I'm 100% convinced that the turbocharger is damaged in your case. You can remove also the exhaust pipe out from the turbocharger, and see if there's a lot of oil coming out.
Repair or replace bad turbocharger with a new one (or with a second hand in good condition one). Good Luck!

BLUE SMOKE FROM AUDI RS6 ON DE ACCELERATION AND START UP THINK OIL STEM SEALS ARE LETTING OIL THROUGH. CAR RUNS FINE I THINK, AND EXCESSIVE BUILD UP OF OIL IN DRIVER SIDE TURBO PIPE, 62000 MILES WITH A...


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.

It is sometimes hard to start my jetta tdi. When this happens and I finally get it started, qite a bit of thick smoke comes out of the exhaust. Any thoughts?


It is hard starting my VW 2003 Jetta. It usually take 5 to 10 cranking before it turns over. Then it run normally. It only happens when the car has not been driven for about 6 hours.
