Oil on garage floor!!!!


Yesterday, when I took the car out of the garage at home, I noticed a tiny patch of oil on the floor.

Looking under the car, it appears to be coming from the exact centre of the car (left to right) and just in front of the rear wheels. It looks like there is a mechanism here, but I can't tell what it is - maybe something to do with gear selection. Anyway, there were signs of the oil on this.

The car is going to the dealer this afternoon for them to have a look, but can anyone give me any ideas. I'm scared of RMS!!!

There are only a few drops on the floor, maybe the equivalent of say 8 or 9 drips. The car is a 2002 Boxster S.

Thanks

In order of concern from least to worst:

Oil pan plug

Oil Filter

Cam Covers

Valve Covers

Rear Main Seal

Did you have a oil change done recently?

oil leaks

I was lucky, they checked out the car good while it was still under warranty, here's the deal:

I was about to buy the car from Mercedes of South Bay, which I did, they held me there, captive in a way, to get my measly 2002 MR2 details, does it run good? all that...so I rode in the car, sound, everything good, but he directional signal stuck, no signal...they said at Mercedes okay just go with them under warranty, so I did...anyway you expect a a bad story, but they checked out my car big time at Porsche! Under warranty they smacked up the RMS, did the deal with the clutch and worked on the windows (up/down when the top is down) and a coolant leak and I was amazed that they were so honest, so they showed me the bill: over $2800 of work down under warranty...goooood people, they could have blown me off, not telling me about the RMS or anything else, and no prob since and I even have a 2 year/24,000 warranty on the work, go tell! and I asked Toyota, the MR2 I used to own for service, lies all around, point is German cars run great as they say, and it's a point of pride to do good business, thanks Pacific Porsche, you pimped my used ride!

OK, it's the worst case scenario!!

Took it to OPC Liverpool, and they immediately diagnosed RMS failure, which is what I thought. Fortunately, the car is still under warranty, and this failure is covered.

They can't take the car in until 3rd May (!) and when I do they need it for 2 full days, which I guess is probably normal. However, he said that the leak was small, and therefore it is OK to drive until they take it in. I'm a bit concerned - is there any chance I could do further damage?

I've heard a few stories about RMS failure, and it being a weak point on the 986 and the 996. I'm now worried, because I've only had the car since December, and I've already been affected. The car is a 2002 Boxster S by the way. Is there an upgrade to the seal that the OPC will fit, or is this failure likely to happen again in the future?

Thanks for your help.

Paul

If oil leaks from the oil cooler on top of the engine, the rear crankcase bolts, or from the intermediate shaft flange seal, or the intermediate shaft flange bolts, then engine oil will show up in the same place it does for when the rear main seal leaks. The exact source cannot be determined until the transmission and flywheel are removed. This is why there is a new repair procedure.

The good news is that there is a new seal that just came out with the 997/987. This is the 3rd version seal. It is the same size as the 996/986 seal so now that is the replacement for the prior models. The bad news is that there are 2 confirmed leaky 997s with this seal, and a 996 owner from Liverpool with this new seal.

If your crankshaft is not in specs then a replacement seal, if it is the RMS, will most likely leak again. We have a local Boxster owner and the 2nd generation seal was replaced 5 times, then Porsche gave up and put in a rebuilt engine - which is another story. The 996 owner I mentioned had 6 replacement seals. What month and year was your car made?

Monitor the oil and just drive it. You do not have a gusher.

Angry

I simply cannot understand why Porsche cannot get this RMS issue handled. I don't know of any other car where this RMS is such a weak point.

If this were a Kia, perhaps I could understand the inability over 8 years to resolve what should be a routine engineerning flaw.

Porsche has been making flat sixes for HOW LONG??????????????????????????????/

Crankshaft Oil Seal leak

Hi there, I think I have the exact same problem. I bought a 2004 Boxster with 29,000 genuine miles, 6 weeks ago.

I have noticed 3 different oil patches on the garage floor when taking the car out but only after I have driven the car a reasonable distance - if I just run in it on the drive prior to cleaning it and after then pop it back in the garage, it doesn't leak.

I have spoken to the german car specialist I use for my Audi S4 and they said its the rear
crankshaft Oil Seal which I guess is the RMS, they also said most Porsches leak from the same place and not to worry too much - is this so or should it be investigated further?

I would appreciate any feedback.

My mechanic told me basically the same thing when I got mine about 6 years ago. I wouldn't obsess over it unless it starts to get worse. Mine actually improved and most of the time isn't even noticable.

Mine has been leaving a drop of oil or two on the garage floor for over a year now, who knows how long it has been before that. I have the new seal, just waiting for a good weekend soon (along with new clutch) to drop the trans and do the work.

Don't mix this with IMS failure, if your only getting some spots, keep an eye on the oil level and use it as normal. Unless its leaving a pool, I would not be overly concerned (plus leave some card under you car in the garage!)

Have you heard of catastrophic engine failer? Don't drive , have towed to garage! Mine was IMS failure, in May last year. Paid $6k and I'm rebuilding now.

I think all crankshaft seals start leaking at a certain point. As long as the oil is not pouring out isn't this something that you could just live with until the clutch needs replacement?

Unfortunately, oil can leak from this location when the IMS flange seal starts to deteriorate. I have no idea what the difference in odds are between an RMS and a IMS problem.

The PPI diagnosed 1.5 years ago on my 2001 Box base said there was mist of oil etc-
RMS leak was implied. Had installed IMS Guardian. Now 50k miles. I have stopped worrying about it till it needs a new clutch or it implodes.....
