I have 17,000 miles.  I have a leak at the bell housing area.  I don't see under the truck where it's coming from.  It's crazy.  Any one have this problem?   I have to take it back to the dealer!

Welcome to the forum!  You will find good ideas from other proud GM owners!  Definitely take your truck to the dealer.  Things happen and you have a warranty to protect you from such problems.  The sooner the better because no one appreciates oil dripping on their driveway!

If you get under the truck there are shiny circle plugs in the bell housing the pop out and you can see if oil is in there buy sticking your fingure in and seeing if oil is there.
Also gm changed the oil amount required in this truck so even if you are not over but on spec, it needs to be at the updated amount of oil. I run low oil for a week or two before I top off.

Just had mine at dealer for an oil leak that was there since 2500 miles old and it turned out to be lower oil pan. I originally thought it was rear main as it looked like that, only sweated never dripped.

WoW that is rare to impossible. They are glued down by a automated robotic machine. You are the first I have ever heard of that.
When I removed mine it was very difficult, even scraping of the glue was hard.

Maybe the robot streamed too much porn the night before and was a little off.  :crackup:

My 2018 5.3 was seeping oil in that area, they pulled the lower oil pan and re-sealed it.  It doesnt leak anymore but the tech was very sloppy with the grey sealant, crazy excessive amounts of sealant from the edges and around bolt holes.

Rare indeed but not impossible as robots, machinery materials etc. have their moments.  I am fairly certain that the L84's L87's have gone away with the stamped portion and now looks to be full cast.
