Leaking from ?

[carrera mike]

Ive had this very minor leak and narrowed it down to be coming from these units. Could anyone tell me please what they are? Are they Cam Position sensors?? They are located forward and aft of the # 4 spark plug on the left side of the engine and forward and aft of # 3 spark plug on the left side of the engine. Nearest to the variocam chain. Theres tota four of these bad boys. Only the two on the left side of my engine are leaking though.

These ones I have on the left side are both leaking oil through their O-rings. Somehow I can not find the part nos of these o-rings with my PET.

Thanks in advance.

A great enthusiast just directed me to the right PET illustration figure 103-11. (I was looking at wrong illustration 103-00 earlier)

They are # 40 and # 41, which are Variocam Actuators. The O-Rings I need are as follows:

-For #40 996.105.903.03

-#41 996.105.903.05

Is that what could be leaking on my car. On the passenger side. I haven't removed the heat shield but if that's the possibly I might as well order the o-rings and take a look at it.

Any more information on my question above? Are they on the passengers side? I have a leak there.

I have a similar leak on the driver side cam sensor. Just last week I pulled out the collar, cleaned the surfaces and put some gasket-from-a-tube on all contact surfaces. May not last long. Thanks for the O-ring part #'s. I have a feeling I'll need them eventually.

Could be,,they are on both sides of the engine.
