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

i thought Porsche's don't drop oil. I noticed this yesterday and looked from underneath, i saw a drop of oil on the floor of my garage. (on the passenger side, under the engine) I am kind of worried, is this fixable? have you guys experienced this on 01 C4's. I figured i don't buy the 1999 996, since that was the 1st year & they have fixed problems on 00 & 01. but oil drops? that worries me. Should i take it in & what is involved in fixing oil leaks. THe car is under warranty, but i would like to know what causes oil leak & what you guys have done to fix.

POST 2Original post

Porsches are known for leaking oil. Especially the older air cooled models. I have a 02 C2 that had a few drops on the driver's side. It ended up to be the cam cover and it was fixed under warranty in 2 days. Originally they thought it was the rear main seal but it wasn't. I guess these typically leak in the middle. Anyways, you should bring it in and get it checked out.

POST 3Original post

Yellowbmr, I had the same thing. My issue was the return tube. The bad news would be if the oil drip came from the center of the engine.... RMS (maybe). If the oil drip is on the side it's probably something else. As for the Porsches dripping oil, its true for the aircooled models but its not for the watercooled. I had a '78 SC coupe for several years, so I know about the dripping oil. By the way, if it is the return tubes, you might as well replace all six. You would already be paying for the labor, the parts aren't that expensive.

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