These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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

Looks like a sensor (temp, Cam?) located over and behind rear most plug coil on passenger side. 99/996 C2. Casing next to it has the variocam insignia.

POST 2 / ORIGINAL POSTEROriginal post

Quotes source post: 9731571

Can it be replaced without draining the oil? doesnt look difficult to replace.

POST 3Original post

That is the vario cam adjuster, you cannot replace it without taking the cam cover and cams out, You can replace the seal around it by un pluging it and removing the 2 10 mm screws. But the adjuster if its leaking is problay beyond the scope of your average diy guy.

POST 4Original post

Clean up the area and then keep an eye on it to see where the leak is. If it is the seal around the cap it is easy to replace. It could also be from the connection above this ara where a breather hose from the AOS connects to the 4-6 head.

POST 5Original post

Here is what you need. You should be sure that the leak is coming from the seal here first before you just go ahead and reaplace. I have done both of mine. Very easy job. Just be careful not to damage the seal when putting it back in place and be sure to get everything very clean. http://www.paragon-products.com/Cove...105.223.52.htm

POST 6 / ORIGINAL POSTEROriginal post

Thanks all. It appears to be the only source of 'clean' oil flow, the rest looks like accumulation. I'll clean it up and watch it. Its counterpart on the other side is dry.

This is a source reference. Confirm exact model applicability in the original material.
