2018 5.3 oil pan area leak

[1SLOW1500]

Guess what surprise it wasn’t the oil pan, still leaking. I said to them rear main seal, of course lets do the easy fix.

Ok what about oil lines. There have been a few cases of small leaks. Worse under pressure so it was hard to find.

Noticed mine leaking around the pan area about 2 weeks ago (2016 with around 57k). Dealer found the pan seal leaking like others above. Said they have seen a fair number of them. They replace the whole pan and reseal, to ensure the pan isn't tweaked from prying it off. Luckily still under powertrain warranty. Been about a week since it was fixed. I need to climb under and check to see how sloppy they were with the sealant and ensure that stopped the leak.

My 2020 taho had oil pan leak at 8k miles!

Ok I took The truck in for service.   They said one of the oil plugs had to be resealed.  Sounds like nonsense to me.

I now have 2000 miles on that fix.  Last week end I helped my son move and the low oil display popped up.

I check the oil dip stick and there was no reading.  We put 4 quarts in and the stick read.  This thing is dumping oil all over the place.   My drive way looks like an oil field !  It goes right back next week.  Now they tell me it will cost 135.00 an hour for diagnostics!  I will be getting rid of the leaks and truck just as soon as they plug the leak.

Oh yeah,  the leak started as a drip off the oil filter.  I did the oil change at 10,000 miles.  That's when I noticed the oil droplet.

It' a GM nightmare !  I wonder how the Fords are.

Well Trucker84 I must say you push things to the limit. 4 quarts low, 10 k oil changes. Wondering if you plan on keeping this truck.

diyer2, I did the 10K oil change.  The oil is changed every 5k miles.  The truck holds 8 quarts. GM must have increased the Qts because of all the leak problems.  I never ran the truck out of oil.  It has a warning that pops up in the gauge display.

When that display pops up, their are still about 4 quarts left.  I am looking at the Dodge Cumins.  The oil leaks are unacceptable for a vehicle with 22,000 miles.

So you wait until the low oil light comes on to add oil?

That isn't it
