Can anyone identify the part I pointed out in my photo?
Dealer appointment made.
Any help would be appreciated!
Talked to the dealership, they said it's the lower oil pan gasket. They're resealing it this afternoon along with a DEF reflash (service bulletin).
Dealer called again. They advised that they ordered a newly redesigned lower oil pan from the GM factory.
If you have a 2020 L5P, you better crawl under and look for oil leaking from the lower pan.
I guess I'm relieved that it's not a rear main seal leak, but still not amused that my 2,300 mile truck needs this repair.
