Oily tailpipes?

[mknittel]

Just turned 2000 miles this week on my 2015 pp. I ran out of the free car washes the dealer trew in so I washed it in the driveway today.

As I wiped it down, my detail cloth turned black when I wiped the tail pipes. Then I ran my finger inside the circumference of the pipe and had a load of black oily gunk on my fingers.

I've seen this on cars with worn out rings and loads of blow by, but on a new car? Anyone else experience this?

Normal for DGI engines. PCV blowby + soot from combustion. Check intake piping/intercooler for pooling, THAT would be an issue. If you have access to E85, you can mix a gallon or two to a full tank of gasoline (straight or E10), might help clear it up quite a bit.

Whats the best way to check the intercooler?

A USB boroscope should work pretty well for inspection, but you can also use the engine oil dipstick to see if there's any buildup/how deep. Car should be level or lower on the passenger side for best results. Here's a writeup on how to check/empty it:

A USB boroscope is best for an actual inspection, but using an engine oil dipstick will at least show you if there is any buildup/how deep. Keep the car level or lower on passenger side so if there IS anything, you can easily see it/measure it. A HOWTO on how to empty the intercooler:

I noticed the same thing with my '15 non PP SHO. I know back in the '80's it was recommended for turbo cars to let them run for 2-3 minutes before shutting off the engine. This was to burn off the excess gunk before it coated the inside of the turbo. Is this still a valid recommendation with the eco boost engines or is it not necessary? I only have 2700 miles on mine.

The turbos are oil AND water cooled, so not really necessary, theoretically. HOWEVER, if you have just been exercising them hard, it is still a good idea to idle for a minute or two to let the coolant and oil cool down a bit and take heat away from the turbos before shutting the engine off.

The old turbo timers were for cooling the the turbo. With the thermal siphoning that is built into these turbos, it is not needed. I do agree that if you are blasting it, say at the race track, driving easy for a minute of 2 is probably beneficial. I figure that by the time I make it back to the pits, I'm good.
