Truck shopping...

Look for a leaking transfer case, the internal pump would rub against the case and wear a pinhole in the case and leak fluid out.

Probably driving my last GM truck. Now I have a 2015 GMC Sierra 1500 4x4. At 4K miles number 4 cylinder intake lifter failed. Of course fixed under warranty and dealer said no issue with the camshaft. Fast forward 2023 with 100K miles, camshaft failure number 4 intake lobe and lifter. I should have sold it when the lifter first failed but hind sight is 20 20.
Replaced the camshaft n lifters with a BTR kit. $3,000.00 it’s doing fine now. I think the AFM contributes to it but the problem is cheap Chinese parts that GM uses to build their engines.
I read about some kind of lawsuit against GM about this but I’ll never see a penny from it.
F150 will be my next new truck.
