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.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

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

Suggestion
I also noticed some oil, not a lot, in the intake manifolds when I went to clean the throttle body on my 2000 base with just under 90K.

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

I removed one intake runner on my 2000 Boxster for some other work and noticed there was a fair amount of oil coating the insides of the intake. Anyone no a possible cause or is it just normal to see some oil on an 80,000 mile engine?

POST 2Original post

Probably AOS going bad...do a search and you'll find lots of posts on the topic.

POST 3Original post

Some oil is normal, like a lite coating. If it's puddling, you probably have an AOS going bad.

POST 4Original post

I also noticed some oil, not a lot, in the intake manifolds when I went to clean the throttle body on my 2000 base with just under 90K. I have subsequently replaced the AOS, not sure if that took care of the issue or not. Ed

POST 5Original post

There's some in mine, too. I suspect there's some in everyone's.

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