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 5Original post

Good spot whoareya. Maybe also a different number of vanes in the each of the Turbo applications? Perhaps also angled differently too? ~ Maxie

POST 6 / ORIGINAL POSTEROriginal post

There also appears to be a port near the exhaust inlet on the 993 turbo. Maybe oil return?

POST 7Original post

Hi, Exhaust housing/mounting flange section is different between 996/993 TT... Mike
