2014 6.2L Bad Bearing Sound

[wacko]

2014 6.2L 4WD

Sounds like a bad idler pulley but I removed all (3) belts and sound remains.  

 

Oil pressure is 35-40 at idle

 

truck runs perfect and has no CEL 

 

heard the sound after after an auto start and trying to diagnose any guidance is appreciated.

Try a automotive stethoscope to localize the source of noise

That is the plan tomorrow... kind of leading towards output side by the flywheel

Well it’s looking like the dreaded lifter issue and while it can be repaired I’m going to go with a GM remanufactued engine.  Oil usage was slowly increasing and while the lifter issue is not a huge deal to repair I figured that with the oil usage issue it is a better route...

What is that going to cost? I have a 14 6.2 and my oil usage is up slightly from when I got it new.

$5,400 engine 

$1,600 labor

private shop.   I have done him some favors (I own a machine shop). He is giving me engine at cost.

 

when we were diagnosing the lifter issue we noticed very little oil making its way to the top of the engine when valve covers were taken off.  That and considering cost to repair lifters was half or more it was an easy decision.   GM gives a 36month and 100,000 mile warranty so it just made sense.

Wow thats a large bill to pay for a 14 model, i think i would of went to a dealer and traded that one in for a new truck.

New truck best deal is 45k new for K2XX 

Old truck is mint and loaded new one brakes and tires...   used value will increase when new engine is installed.  I’ll hang on to it for 2-3 more years and buy the latest generation when the real discounts hit.  Crew Cab Standard beds with 6.2L are few and far between...
