the oil smell like gasoline

[amerjubran]

Hi,

Own: BMW '93 520i Auto

The oil is mixed with gasoline on the dipstick! (Gasoline in the oil)
any help?

Do you only drive short distances so that the engine hardly gets warm to operating temperature?
Maybe you drive a longer distances so that the engine get's really to operating temperature and then check it again.
I assume that it is gone then.

Any starting or running problems? smoke on start up? Check engine light come on?

3 most common causes are leaky injectors, faulty O2 sensor, faulty fuel pressure regulator.

Search foum for "stomp test" and check the codes. this needs to be diagnosed asap and the oil changed, gas is very bad for bearings.

post with further details please.

This is true for just about all engines I believe. When starting, a little gas will slip by the rings and into the crankcase. Once the engine oil gets up to temperature, the gasoline will evaporate.

Are there other problems you are not telling us about? Cylinder misfire, etc.

there is no running problems nor smoke on start up
but I can here sound (tick tick) from air regulator even after turning the switch off
and high gas consumption

You need a leakdown test.

[BillionPa]

the tick tick thing is the air ventilation control flaps and indicates a failing AC control unit.

.. you need a leakdown test.

I would start with diagnosing the poor economy. It could be something as simple as the plugs are totaly worn out.

Start with the basics. check the tune up even if you put plugs in recently, escpecialy if you used bosch platinums.

Check the codes, it may have a O2 sensor code. If it is running rich and you have no code, the sensor is probably bad. If it has a code, it may be bad plugs, bad regulator, bad sensor, or other less common problem.

Somehow the gas is getting into the oil past the rings, either you have bad rings(not common) or you have too much fuel or poor combustion(common).

i bet the pcv valve is bad.
