I noticed a puddle of oil just under the Air / Oil separator and most probably the culprit is the J tube.

Suspected cause

probably the oil fill tube that runs from the trunk to the engine - it has a joiner right at the aos that will drip oil if you are chucking the car around.

I still ordered a new j tube,as I said, wasn't expensive so worth replacing anyway.

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

I noticed a puddle of oil just under the Air / Oil separator and most probably the culprit is the J tube. I noticed that the O ring was thorn. Should I try to find some replacement O rings or should I just buy a new J tube?

POST 2Original post

You would likely have a vacuum leak and idle issues probably accompanied by a CEL if this was the culprit. I mean, it's cheap enough you can do it easily. But I'd think if it was an issue you'd have other symptoms.

I just ordered the j tube, wasn't expensive anyway. I'll see how it goes after I replace it

I will check about that. I didn't know that "chucking the car around" could cause oil leaks. I still ordered a new j tube,as I said, wasn't expensive so worth replacing anyway.

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