I took it to a dealership to get everything checked out and the oil changed last weekend.

My guess, and I'll stress guess, is that whoever changed the oil didn't use a new aluminum crush washer under the drain plug and just re-used the old one.

You may want to check the torque on the drain plug to see if it's fully tightened.

If nothing else, I would THOROUGHLY clean the protection plate (both sides) and clean around the sump and drain plug.

Yes you have to change your oil again but if you do it right (clean catch container) you can reuse the oil.

Suggestion
Do this when the engine is cool/cold, lay down a drop cloth or cardboard as you will lose a small amount of oil, remove old drain plug and block the drain opening with your finger (little Dutch boy style), quickly replace new drain plug/crush washer.

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.

2000 C2 21000 miles bought it two weeks ago. I took it to a dealership to get everything checked out and the oil changed last weekend. Since then I have been leaking small amounts of oil from the location in the picture. A small hole in the rear skid plate. Looks like the oil plug? It only leaks after long runs. 30 minutes or greater. May I assume this is normal after an oil change? This thing wont let me post pics yet.
Thanks

Oh yeah, I am a first time owner, 29, Missouri, and if I could I would make sweet love to my Porsche. I love this car. I also own a 2002 Subaru WRX which I bought new in 2001. It has 120000 miles and running perfect with a COBB stage 2. OK, enough. No I dont have pictures yet of the car. Its that dark metallic blue with full black leather, litronics, badass premium stereo my ***, and its an aero with turbo twist 18"s.
Someone here will recognize your plug seeping but not me...Now I can diagnose your garage problem. Lack of shelving, paint....all common problems that can be fixed with a few trips to Home Depot
Oh, me....I did stay at a Holiday Inn last night
It certainly looks like it is the oil drain plug from what I can tell and your description. There is no reason why a Porsche or any other car should leak, or at least can't be made to stop leaking. The good news is that it is relatively cheap and should be a fairly easy fix.
My guess, and I'll stress guess, is that whoever changed the oil didn't use a new aluminum crush washer under the drain plug and just re-used the old one. While this is a great way to save 50 cents, and you may get away with it not leaking, it will make a nice mess of your garage floor when it does leak. You may want to check the torque on the drain plug to see if it's fully tightened. I believe 37 ft-lbs is the correct spec - don't wrench on it if it's already tight. If that doesn't fix it then I think you can guess how you'd replace the crush washer and it involves draining the oil again.
Anyone else care to chime in?
Well then, take off the skid plate covering your engine and determine if the drain plug is leaking, or something else is leaking and you just happen to notice it on the drain plug because that's all you can see.
Do what Doug suggested. I had the same thing happen with my CAB and I realized after taking the protection plate off that oil sprayed onto the plate (non visible side) when I drained the oil and now it was "leaking" that extra runoff. I would start with that. If nothing else, I would THOROUGHLY clean the protection plate (both sides) and clean around the sump and drain plug. Then check back and if there is a small amount getting out of the drain plug I would head over to the dealer and for less than $5 you can get a NEW drain plug and crush washer. Yes you have to change your oil again but if you do it right (clean catch container) you can reuse the oil.
If it is your drain plug and/or crush ring you can replace it w/o draining your oil, if you work quickly! Do this when the engine is cool/cold, lay down a drop cloth or cardboard as you will lose a small amount of oil, remove old drain plug and block the drain opening with your finger (little Dutch boy style), quickly replace new drain plug/crush washer. And when you replace your drain plug don't over torque it. They are soft and crack easily. Don't ask how I know.
You can even do this when the engine is warm in the case of an emergency.
At the last clubrace, I learned that a mechanic had overfilled my oil a little on my '44 race car (I had some work done shortly before the race). When it is overfilled, it puffs smoke when I go around corners, and it could be bad for the engine. So, without much time before qualifying, I decided to drop a few quarts from the pan. Engine was still warm, but not hot to the touch. So, I loosened the plug and held it there so I would not lose all of the fresh oil. Problem was that, although the pan was not "hot" to the touch, the oil was hotter and it "stuck" to you. So, I got a second degree burn on my thumb where I was holding the plug . . . but I made it to the grid for qualifying on time.
