Now that many 991.2 GT3s are out of warranty, has anyone had this issue fixed out of warranty? Seems like the labor cost will be quite high with having to reposition the engine to gain access to the pipe. I don't have any drips on the undertray currently, but I have not yet inspected the area around the crank oil feed line. If there is minor seepage or a few drops of oil around the pipe, are most people just monitoring it at every oil change?

Gave my car to a Porsche specialist workshop at the end of last week for Dundon Street Headers and PDK full Maintenance (OIl pan, new oil and new clutch oil). Just made 20km to go back home and park the car in the garage. Today, I found a 10cm diameter oil stain on the floor at the left rear tire.I wonder even if it doesn’t sink on the tire
New oil, transparent, no particular odor.
I can't see anything under the car, it's too low. I had a trip planned within a few hours...what a disappointment...do you have any suggestions on what I should check and how?
There were no oil anywhere before the service, maybe a a poor tightening?

Oil fill tube overflow?
#128
Is there an overflow tube in this area?
Maybe a vent tube if there were too many oil during maintenance?
Does Dundon headers could overheat something?

So we dismantled everything...and it’s dry, not a drop in the protections or diffuser, not a drop that would explain the place where I found the oil on the floor...mystery!
But...on an angle of the PDK oil pan, it was clearly oily.
Of doubt, we did the complete emptying with a new Pan and new pan screws...I drove 100km and after 1 hour pause...another drop on the floor...I don’t understand...
I’ll leave a few days and see how the garage floor is...

Had mine replaced under good will from Porsche. The engine has to come out for this job.
updated vent tube is a lot longer.

Thanks
Is this vent tube visible without disassembly?
Maybe after the may be that after refill/emptying, there is more oil in the PDK and it is more fluid, so I can maybe let it naturally remove excess oil?
If we can access to the tube, I can maybe insert a catch can inside?

There is a one way check valve in the tip of the tube. Here you can see an oil droplet forming
I experienced this leak on track after a full PDK service (fluid & filter/pan change) the tech says the fluid level was verified via PWIIS after PDK service. I lost about 0.75 liter on track mostly splashed in the wheel well area and some hit the exhaust and smoked on right hand turns.
Porsche’s TSB solution extends this tube 5x and places it on top of the transmission. No more leaking observed after the work.

Well, after a 250km run in french alps with many hard drive parts, I parked the car in the garage for a week.
I checked today, not a single drop of soil on the floor...I'll check also after next trackday, the car will be pushed harder.
I hope the change of pan and screws solved the issue

Has anyone replaced the crank feed oil pipe themselves yet? I had my car apart to change the serpentine belt, and noticed this leak where the hose inserts into the cap, as well as a leaky tensioner. I've already ordered the tensioner, but need to figure out how to replace this oil feed pipe.
It looks like the cap slides off, requiring replacement of some o-rings. It looks like the ac compressor has to come off, but it appears to be a hard connection, where it can't be moved to the side without opening the system.
Thanks,
David

It looks like the AC compressor can be moved out of the way. Only a portion of the lines are hard lines. Not a GT3 in the article above, but the compressor should be a very similar part, if not the same part.
