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!

Drive it until it blows up and then take to it the dealer.

Rear main seal.

Over filling with oil can cause this.

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.

      Help purchasing a touch screen digitizer

      By mark249 · Posted

      Brought my 2015 Colorado into the dealership to check my touch screen issues, had that ghost touch thing happening. They said I needed a new touch screen and they could either order me one for $500. The lady at the service deck was nice enough to tell me I could order a touch screen online for less, she did stipulate that the touch screen had to be factory OEM, you can't pair an aftermarket screen to my radio seeing it was 2015, it had to be a GM factory OEM only. I found a few on Amazon and Ebay by the numbers on the back of the old screen, DJ080PA-01A GM# 22740886, Some said "OEM" in the description and others just said "Replacement". Would a replacement be the same as a OEM as long as it had the same numbers on the back of the screen? In some of the descriptions they also show different brand names but same numbers, is that an issue?

      I have both but typically use the 4 legged walker (wheels on front, ski's on back).   The four wheeler is starting to be used on "longer" outdoor walks.  The 4 legged walker is particularly helpful in practicing good walking posture.  Both of my knees are at different stages of recovery and I'm trying to not develop poor habits.  I can actually manage with a cane but it's very difficult not to favor one leg over the other.  My PT recommends I continue with my 4 legged walker for a while.  Yesterday was four weeks since my last knee replacement and I'm excited about my progress to date.  It has been a hell of a rough journey so far but it is exciting to witness  systematic and continuous improvement.  I went for years watching the decline of my "mobility".  It seems that everyday now I am alerting my wife to something I can do now that I couldn't a day or two ago!  I encourage anyone facing the prospect of knee replacement to share any concerns with others who have had the surgery.  It isn't an instant fix but rather is a considerable amount of short term pain for long term gain.  Recovery time and pain levels vary for individuals post surgery but the end results are typically very positive and I've never encountered anyone regretting having had the surgery.

      The lifter issue can be dealt with by shorter oil changes and quality oil IMO.

      Wiring Help, Please

      By Core-Lokt · Posted

      I'm putting in an A-pillar pod/gauges, and I'm asking if anybody can identify a (preferably) fuse for a switched power and illumination circuit on the driver's side interior fuse panel. Offhand, everything I checked with a test light was constant-hot, and I'd much rather uses a piggyback fuse. I can certainly find a wire, but I'd rather not half-tap.   Thanks in advance for any help.
