I change the oil in my 2019 Targa a month ago. I purchased a new drain plug from the dealer and used that for the change (yes, it included the rubber gasket already). When I finish changing the oil I sprayed a little bit of brake cleaner on a rag and cleaned up the plastic oil pan so it looked nice and clean without any oil spots.
fast forward to today, I gave the car a wash and decide to look under the engine for the moment. I was surprised to see how wet it looked near the drain plug. I grabbed a rag to clean it up, it wasn’t oily or the rag didn’t catch much, it was just dirty.
Is this wet look or seeping normal? the plug is tighten to the correct location (arrows line up). No drips or anything on the garage floor.
Interesting. It does seem to be oil to me. I would avoid using brake cleaner as it may have degraded the rubber seal leading to oil seepage. I would recommend Simple Green next time to clean up any oil.
The bathtub drain stopper AKA plastic oil drain plug has just one position when it's locked : the way you have it,where the 2 arrows on the side line up with the line that goes across the drain plug. Do not try to tighten more as you will strip it. It's very important to replace it at every oil change as it will come with a new rubber O-ring,which is where the sealing happens.
In your case it's probably not leaking,it's just residual oil that got trapped between the plug and oil pan,which came out when the oil pan got hot.
Monitor it a couple of days and it should be fine.
Nope, it should be bone dry on any oil pan on any car.
Use a water based degreaser and fully clean up all the oil residue including the oil pan area forward of the drain plug and up the engine case. Then monitor it daily to see where the leak initiates. I highly doubt its the oil pan gasket; the car is new.
BTW, use a 1" wide bristle paint brush or tooth brush in the cavity around the drain plug when using the degreaser.
Just did a recent oil change on my '23 992.1 Carrera T (same plastic sump and drain plug) and also have this same wetting condition. I could understand the wetting condition if perhaps the drain plug o'ring has hardened from heat, but being new, wasn't really expecting this. The particular plug name/part no. that I used is a Corteco 49379182 from FCP EURO. Wondering if this just an issue with this Corteco product.
I dislike the plastic oil pan and 1/4 turn drain plug. I wonder why the change..... if you priced the plastic oil pan it definitely wasn't cheaper.
I had weeping after my 1st DIY oil change....... the 2nd DIY change I really made sure the hole was cleaned up as much as possible before insertion of the new plug and it's been dry.
That does not look like seeping. It looks like residual oil from the draining process and the shop did not clean it up after to provide a "clean pallet" to monitor things. After every oil change the pan looks like that until you clean it. You should clean it to ensure if there is seeping, there is no confusion about where it came from.

From the service information booklet:
1.3.5 Oil pan
The oil pan of the 911 Carrera model year 2017 engine is a two-piece design. Both parts are made from plastic and have integrated air/oil separators.
The plastic lower section of the oil pan is designed to absorb impacts without the plastic breaking.
Oil drain plug
The oil drain plug is also made of plastic and must be replaced when removed.
Service
Only the oil drain plug including sealing ring is available as a spare part. In the workshop, the oil drain plug must be removed using a suitable Phillips screwdriver.
The day I created this thread, I cleaned the oil pan with simple grain and scrubbed it. I just checked the oil pan today, and the wet look is back near the oil plug. Although it looks wet, when you touch it, it is not actually wet at all it’s just dust, kinda resembles brake, dust if anything. I wiped it with a clean paper towel and it’s all dry just dusty. I’m going to assume this is normal, I change the oil myself, and the oil plug is at the proper position (arrows align). I purchased the plug new from the dealership

Do you spray the area surrounding the drain plug after you have completed draining the old oil and installing the new plastic plug and elastomer O-ring? I used some plastic-safe spray can solvent, e.g. for cleaning modern electronics connections or a mass air sensor because these don't contain any solvents that will damage most plastics. These solvents also evaporate quickly, so you need to wipe down the area immediately after spraying them. Doing this enables you to more easily spot a seeping drain plug or other leakage. The plastic lower oil pan cover is "oil philic" as many plastics are, and has by design lots of nooks and crannies between its reinforcing ribs that add to the surface area on which oil will collect, and thereafter dirt if not cleaned after installing the new plug.
Hello i had similar less than is on picture just sweat on plug not around plug after porsche dealer change they did not clean it up. I was visit indy mechanic he spray plug with cleaner and blow up with air gun and its bone dry now.
