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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Regards Steve Migration info. Legacy thread was 14560

POST 2Original post

doesn't sound good, exhaust gases out of only one exhaust would lead me to conclude that your valves are only fully operational on one bank of three cylinders. Cam or cam belt failure? Not sure if 996 cams are belt or shaft driven? Migration info. Legacy thread was 14583
