Basically, I replaced a missing Changeover Valve on the left side of Engine Bay (standing from rear of the car) and also replaced a second changeover valve on the actual air box (that one was missing as well).

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.

POST 1 / ORIGINAL POSTEROriginal post

Guys, I'm trying to figure out vacuum lines routing for a couple of changeover valves on a 2006 3.8L with Factory PSE (Porsche Sports Exhaust). Basically, I replaced a missing Changeover Valve on the left side of Engine Bay (standing from rear of the car) and also replaced a second changeover valve on the actual air box (that one was missing as well). For the life of me I cannot figure out exact vacuum line routing for these two valves. The resonance flap appears to be unplugged and resting on exhaust manifold. There are numerous vacuum line diagrams floating around but none for a 3.8L with PSE. Which appears to be slightly different vacuum line routing compared with the 3.6L or even a 3.8L without PSE. Thanks so much in advance.

Didn’t know there was a COV on the air box Is the a 997 or 3.8 thing?

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