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

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.

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...

      I think the answer is it's a stock 5.7 Hemi with a 3.0L blower bolted onto it 😉   Practically, because a blower introduces a lot of high pressure, severe thermal stress, and extreme mechanical loads on an engine. Things still need a little time to seat and get used to moving under load.   Sarcastically, because it's a Stellantis/ 5.7 Hemi and those things need all the help they can get!!

      It's been a little over three weeks since my second knee replacement.  I can now walk around the house without a walker or cane but still have a lot of healing ahead.  This morning I was able to bring a cup of coffee to my wife in bed.  A few days ago, this coffee would have ended up on the kitchen floor!  Knee replacement surgery is very common and will typically enhance the recipient's future quality of life. However, the recovery process can present significant challenges, pain and discomfort. I encourage anyone facing a recommended total knee replacement to welcome the opportunity.  Just be aware that your body may take several months to fully welcome the new parts!

      The Germans basically didn't make the list. There aren't a lot of shade-tree mechanics who work on them in general. At some point the economic equation of keeping a car alive favors junking it. Anecdote/experience tells me this is the case versus actual bad engines/engineering. Not that there isn't any, but there are definitely notable excellent examples. The 2.0 diesels will go forever and ever if one keeps the car around it running. The 2.0 gas cars eventually wear out their turbos but the block below it is usually still solid as a rock. BMW inline 6's same thing. Mercedes diesels of yesteryear, not uncommon to see 250k out of those engines, easy.     Link to the synopsis of the study: https://www.iseecars.com/longest-lasting-cars-study

      0w20 is recommended in the Sequoia. 0w16 in the Highlander Hybrid.   I think you make a compelling case for both the quality and frequency of maintenance but I wouldn't go so far as to plot a linear relationship between longevity and oil weight 😉   The list is interesting and leaves me with some questions. The Silverado 1500 is 12.9% likely while the GMC Sierra 1500 is only 10.8% likely. Arguably, they're the same truck, so other factors must be influencing the outcome.   The Honda Odyssey ranks #12 at 13% likely. Great. Rest assured we'll never stop hearing about the dang thing LOL.   There's a bit of a spread between the 4Runner (32.9%) and Tacoma (25.3%). Both overlap on the same 4.0 for many years although the Tacoma used a 3.5 for the last 10-12ish. I wonder if that's related to use-case or if it's suggesting the 3.5 isn't quite as up to the task, or maybe something else fails mechanically.   Ram at 3.5% overall likely, but the Ram 3500 holds the top spot on the Heavy Duty Models at 39.7%. One might say the Cummins is a ringer and provides an unfair advantage. I don't think it's fair/accurate to pit the GM Fullsize 1500's in a list with HD's which are basically medium-duty wearing a 3500 badge.   The Tahoe and Suburban hold spots #15 and #8, respectively, on the longest lasting SUV's list. What's the difference? One's got a shorter butt, unless they're also counting the 2500/3500 Suburbans in those numbers.   The GMC Canyon gets a 1.4% increase over its twin brother Colorado. Why, because it's prettier?   SO many questions...

      Have the aftermarket system removed an re-test.  Its pretty much the only way to know if there is still an issue that is the truck and not from that.
