Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
Occasionally a well meaning mechanic may over tighten the bolts hoping to stop the leak which paradoxically gets worse

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

Hello. I have 2 valve cover gaskets leaking. DOes anyone has instructions how to replace them as well as how difficult is to complete this (my mechanic will be doing it). Thnak you Steven 99 996 C4 Cabrio with 90% options 102k miles and runs strong

POST 2Original post

They aren't actually gaskets per se, Porsche uses a special silicon sealant on the cam cover. Remember to use the correct torque (10 ft/lb) and sequence as they will not tolerate overtightening. Occasionally a well meaning mechanic may over tighten the bolts hoping to stop the leak which paradoxically gets worse . This info comes from the 996 service manual. You can get the service manuals from Porsche, they used to be a couple of hundred dollars but now they are quite a bit more.
