oil leak after winter storage normal?
Hello folks,
I just got out my 2006 Carerra S out of storage for the winter (live in WI) and I noticed some drips of oil from under the rear end on the floor (need to look closer when I have time).
Just curious if the seals loosen up over time and leak being its not been driven since fall? Prior to this winter, there were no leaks at all. I have only owned the car for a year now, this was the first winter.
Details:
2006 997 911 S Convertible
41k miles
Thoughts?
Thank you,
Brandon

Next service have them put it up and check for signs of seepage/leaking in RMS area towards front of motor. Common and not a big deal (unless you are seeing puddles). Standard advice if this is the case is to wait for clutch to need replacement and do it then. Big savings in labor. I had seal replaced in my 06 at tail end of warranty and am getting slight seepage again after 4 years. Not sure whether inactivity and severe cold would exacerbate the issue but it's a known gremlin with these cars.

If you put it away with less-than-fresh oil, the oil had contaminants that gradually ate away at the gaskets... OR... the gaskets lost some of their pliability and would be very well served by fresh oil and a thorough warming of the engine.
If first issue: Only new gasket (whichever it might be) is the fix
If second issue: Gasket should expand and remain expanded enough after fresh oil rejuvenates it and the heat helps expand it and restores some pliability. Def do this first before going crazy on anything else.

Great feedback guys, thank you. I am aware of the rms leak that's common but I'm hoping that's not it being it was dry prior to storage. We changed the oil last spring and only put less than 4k miles on her so I'm guessing the oils fresh, we will be changing it shortly.
I'm hoping you are right philster and that the gaskets lost pliability. With new oil and consistent driving, I'm hopeful the leak will disappear.

If the car sat all winter then everything rubber looses its elasticity. You will find that after a few heat cycles the leak should slow or go away. Try and get under the car and hit the area around the leak with some brake cleaner or degreaser to really identify if the leak has stopped. Aluminum castings wet with oil will continue to weep for some time.

Sorry, leaky gaskets are not generally known to regenerate themselves. Your leak may slow down, or appear to stop. Short term. But it is inevitable that you need to replace that gasket.

This was an issue for some of the guys that bought a 997 GT3. Some that would track it, and then let it sit for a few weeks at a time, were having RMS leaks. Porsche was saying that the diminished internal pressure caused by the car sitting idle for long periods of time, was allowing the seal to leak slightly.
I would drive it and see if the leak diminishes or stops completely. If it does stop leaking, great. If not, then the OP may want to consider replacing the Rear Main Seal.

Regardless of conjecture OP should have visual inspection of leak. It could be unrelated to RMS. IMS also leaks but it is difficult to differentiate btwn the two w/o taking tranny off. I would not go that far. Could be any # of minor things. If it is RMS it has already been suggested that it can wait. If it stops leaking, great.

What you say is true in most cases. However, the RMS seals requires some internal pressure for it to seal correctly.
