Oil in brake booster


The vacuum is created via a mechanical pump driven from the cam, Or a separate, electrical pump.

The only liquid I have ever found in any servo (booster) is brake fluid from a leaking master cylinder.
If the vacuum is low/absent, due to a faulty cam driven vacuum pump, and crankcase pressure rises, along with a faulty one-way valve in the vacuum plumbing, it's possible the oil could be forced into the servo housing, and operating the brakes would help it happen as the servo could act as a pump itself and draw oil from the engine.

Found some diagrams:

I have an A5 3.0TDI which has a flat spot when


Can you describe what you mean by "flat spot"? Do you mean that there is par of the rev range where there seems to be little power? Turbo engines tend to produce bursts of power when the turbo spools up. Does the "flat spot" happen at low revs? If so, your turbo isn't spooled up yet. As you accelerate and it fires up you feel a rush of power. just a guess, provide more details and we'll try to help

Oil in intake but on oil at turbo side


usually caused by high crankcase pressure, very common in Dodge Turbos-all you can do is check to see that your PCV valve is not plugged, many people who have them use a 'catch can' to catch this oil instead of it going to the intake tube. I have an 88 Shelby Z, since new it has always done this-crankcase pressures are very high in turbo engines, and this is a result, especially when the engines are not 'tight' (oil/compression rings and blowby issues).

White smoke billows out of exhaust. I think it is the turbo.


whatch for a clogged crankcase ventilation system. internal crankcase presssure(excessive) will push oil out the turbo shaft seal. also you have a supply line for fresh oil to the turbo and a return line. if the return line gets carboned up and there is nowhere for the oil to go it will push out through the turbo shaft seal.
