Sounds like the leak that was on both sides of the 996 I test drove on sunday, it was the cam cover seals in that case.

Anyway, looking under my car tonight to evaluate damage from running over a truck tire carcass (ouch, but that's another story), I noticed that the engine behind the left rear tire/suspension is covered with oil/dirt as if there's been an engine leak for awhile.

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 1 / ORIGINAL POSTEROriginal post

Hi everyone. This is my first post, although I've been a member for a couple of years now. Anyway, looking under my car tonight to evaluate damage from running over a truck tire carcass (ouch, but that's another story), I noticed that the engine behind the left rear tire/suspension is covered with oil/dirt as if there's been an engine leak for awhile. No spots on the garage floor though. I'm generally familiar with cars, but I'm totally unfamiliar with 996 engine layout, so descriptions I've seen of the RMS being where the engine and the transmission meet are of no help to me. So what part of the engine is behind the left rear suspension? And where (pictorically) is the RMS? Sorry if I started another long thread on the RMS! And yes, sorry, I haven't posted a picture yet either. Thanks for your help.

POST 2Original post

This is your engine separated from the transmission. The rms is the ring circled. As you can see when it leaks it can make a mess.

POST 3Original post

Are you certain it is oil? Could it be a slow antifreeze leak that has collected dirt/dust? That sounds to be about the right spot for a leak from your coolant tank.

POST 4Original post

Great picture, that actually is very helpful!! SO, the question then is how hard is it to change that seal. Looks easy if and when the clutch is out for replacement and you pop off the flywheel.... Thoughts?

POST 5Original post

+1 for sure other fluids in that area could be......brake fliud, leaking shocks, colant from another source (ie. AOS) oil from any number of areas. Best to take a coule picture if you can, the top notch team here will help you thru the trouble to brighter days........

POST 6Original post

One sided slow oil leaks like this one can frequently come from cam covers. An easy fix. IMS/RMS leaks are usualy at midline.

POST 7Original post

Quotes source post: 6200988

Cam cover seals are a "relative" easy fix. To replace, one should have a cam retainer tool and it's a lot easier to lower the engine.

POST 8Original post

Sounds like the leak that was on both sides of the 996 I test drove on sunday, it was the cam cover seals in that case. It was leaking on the exhaust manifold as well, and the entire bottom of the engine was covered in oil as well...

POST 9Original post

Is it possible to have an RMS issue and not have a visible oil drip?

POST 10Original post

Quotes source post: 6203005

yes... they sweat. then mixes with dirt. But no drip. But, it does need to be replaced. If it's behind the drivers side, near the suspension... it is not rms. RMS leaks in the middle between the tranny and engine. The OP might need a new air oil seperator or in that area is the source of the leak.

POST 11Original post

May also be a spark plug tube. You need to post a pic!

POST 12 / ORIGINAL POSTEROriginal post

Thanks everyone for their quick responses to my post. Unfortunately, I don't have the car here to take any pics at the moment. It's now at the body shop, which was the initial reason I was looking under the car in the first place. On the freeway Saturday night and this big 4x4 truck in front of me kicks up a big tire carcass. It went up in the air high enough to make me think at first that it was an empty black trash bag. But as I got closer and it came down, I realized what it was and too late. Bammmm -- as I drove over it, I just cringed as I heard it hitting the underside of the car. Result, shattered front bumper and torn up shrouding underneath all the way back. Hopefully that's it and all repairable. Thank goodness for insurance! Oh, and to add salt into the wound, I go to start it this morning to drive to the shop.....and the battery is dead! Just not my day. I'll clean up the oil mess and take pics when I get it back. Thanks again everyone!
