I guess it has to be something high up so will see if I can find a crack or if I can just re-seat it as I moved it when I changed the expansion tank last year.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Just thought I'd post this here as more traffic than in the DIY section but any idea why I have found oil pooling in the cast recesses in the engine block below the intake and directly behind where the alternator sits? Picture in the linked thread. http://986forum.com/forums/diy-project-guides/24008-how-change-your-alternator.html

POST 2Original post

Most likely a cracked oil filler tube. This is not expensive but a bit of a pain to change.

Thanks. I guess it has to be something high up so will see if I can find a crack or if I can just re-seat it as I moved it when I changed the expansion tank last year.

Check to see if oil or power steering fluid. m

POST 5Original post

I also had a similar oil pooling/leaking condition in that area. I had a leak in the oil fill tube joint right at the AOS vent hose location. With advice from this great site, I switched to a screw clamp on that oil fill tube joint. I am monitoring the leak. So far, looks better.
