Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

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.

If the short one is 996.605.901.00 it is a solenoid valve for the vario cam and is the short one. (illustration 103-10, item 10 in PET) I don't see a P/N for the O ring for that one, but try 900.123.147.30. If your local Porsche parts counter is any good, they should be able to find the right one. The other one, I can make out a P/N of 996.105.303.02 It is called an actuator and is also part of the vario cam. The P/N for the O ring for that one is 996.105.903.05 (Illustration 103-11 item 41 in PET)

POST 3 / ORIGINAL POSTEROriginal post

Joel Riser helped me figure out 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 -For #41 996.105.903.05

I think your question was answered on PCA.org.

Yup! Joel Riser actually helped me figure it out.
