Do you have an idea why my VW Jetta 1.8 L Turbo car blows out a cloud of blue smoke whenever I take a sharp corner or on-ramp? It lasts about 10 seconds, then stops smoking!

If the oil cap is not missing or loose I would venture to guess you have a bad seal.

Can you see the source?
Is it dripping when parked?

Oil seals really require a mechanic to properly fix. (Unless you have a good torque wrench and do not mind getting really dirty.)

Are you sure the blue smoke isn’t related to acceleration, i.e. when you accelerate out of those sharp turns or accelerate on the ramp? If you accelerate quickly from a stop, do you get the blue smoke?

It sounds like you’re burning oil. It has to be leaking from somewhere. Take it to your mechanic. This could eventually lead to engine failure (if the oil leaks out too fast), and it also pollutes the world and annoys the drivers behind you. I strongly urge you to get it fixed!

I learned a long time ago the hard way – blue smoke is never a good thing on a car. Get it to a mechanic right away – just to be safe rather than sorry.

Sounds like someone’s been feeding your car cotton candy.

Sounds like you are burning oil, probably because a gasket needs to be replaced. Until you bring it in (which should be soon) remember to keep an eye on your fluid levels.

I see you have a 2003 Jetta. You might be eligible for VW’s engine sludge recall. Check with a mechanic. The work might fall under the warranty.
Did you get a mailing from VW? It was a single page letter. Snoop around on the net. You’ll find it.

Sounds like you have too much oil in the crank case.

When you take a corner, the oil is pushed up one side of the engine and is pulled up into the cylinder, thus the smoke. Then, when you straighten out, the oil goes back down into the pan at the bottom of the engine, after 10secs or so, the oil is burned in the cylinders, then no smoke.

too much oil would be my guess. drain your pan and refill with the proper amount. and do it sooner rather than later.

It it’s too much oil, why would his car be using up a lot of oil?

Blue smoke means burning oil. On a turbo engine, my guess is worn piston rings, but it could be the valve guides as well. In either case, you’re looking at major engine work. Get thee to a shop.

Blue smoke is oil. The number one source of burning oil is valve guides, #2 is piston rings. Time for an major overhaul or engine replacement.
Lots of oil is collecting in the exhaust system and exhaust side of turbo. When you stomp on the accelerator, a huge blast of heat and fire goes into turbo and exhaust, creating the smoke cloud.
