318i Oil Leak on Sensor - help

[sPoNgE-SA]

Hey all,

I've got a oil leak under the cover that goes over the plug leads on top of the cylander head. There's a sensor there which I think is the Cam Shaft Sensor. It looked like it had oil on it so I pulled it out and the connectors had oil on them. Will this cause lack of power on low RPM ?

Let me know. Spent money trying to fix problem but find this now. Also I have a leak on the tappet cover could this also cause lack of power?

I cleaned the connector which might of made of difference but I will need to drive it for a few days but I think it might just leak again on the sensor.

Let me know.

It's part number 7 that I'm replacing.
But I would like to know what sensor comes under this seal ?

Wow, where can I get access or download data/repair catalogs like this? I have a 318i too and from my experience of Heynes (sic) manuals - they are not good. Yuor help/guidance will be much appreciated.

You don't download them, you just keep them in favorites, this one is the same as BMW's:

Dont take any notice of the prices, the easiest way is to click enter then put in the last 7 digits of you VIN and away you go.

So gents,

anyone know if this oil leak would of caused a problem or damaged the Sensor?

[marti5]

I would not have thought so, sensors are normally water and oil proof.

Marti is right, the Cam Position Sensor is a sealed unit and it should have oil on the end if you pull it out, it reads directly from a metal piece on the end of the camshaft.
