Have a 2017 Z71 6 cylinder and 95000 miles. #6 main bearing went. Dealer pulled the oil filter and was full of metal. Found a 2019 engine with 19000 miles.

 

I also removed the oil filter and found metal shavings. Big pieces that are easy to see with my old man eyes without my glasses.

 

That just sucks. What was happening before it went out? I have a '18 ZR2 with the 3.6 that locked up. Haven't pulled it apart to see what the cause was.

 

Was driving on Freeway. Oil was changed at first 1000 and every 5000 after.

 

Sounded like an early diesel motor. Still ran but I knew it was trashed

 

Sounds like you both have suffered like 1 other member has on this Forum
Oil on 1 side of the Engine had a issue
That member 1 Side looked great.. The other side looked like old dark golden oil residue

 

That's terrible, did you do your own oil changes? Haven't read about these V6s locking up. What was your Oil pressure usually at?

 

Oil changes were done at 2 different Chevy dealers.

 

It was not an oil pump failure on mine according to dealer.

 

I changed oil regularly, and was fresh oil, about 2 weeks from the last change. I think it has to do with the AFM shutting down 2 cylinders to save fuel. The hemi motor in the Ram has an issue with breaking cam shafts.

 

The AFM in the V6 is not like the V8's
Almost no failures
Locking up most likely is due to Oil Starvation in 1 of Banks

 

My failure I believe is due to a part the dealer changed and the pressure valve was not replaced. It took some time to happen.

 

One of your mains are gone I suspect

 

I'm probably going to wait to get a remanufactured engine like a Jasper when they become available. They're currently in R&D on the "N" LGZ engines

 

I got an engine out of a 2019. 18149 miles

 

My mechanic is a Jasper certified installer and they don't have it. Any suggestions or help is appreciated. Thank you

Jasper doesn't have 2017 and up reman 3.6L engines?

That sounds really odd seeing how many of these 3.6L engines are on the road.

Until now...

Just because there aren't any reports of widespread failure does not mean there aren't a lot of failures going on due to AFM

One would have to inspect every trashed engine to determine the cause of it's demise which nobody is doing so saying there almost no failures caused by AFM is just speculation.

The fact of the matter is AFM is just more crap to cause problems and no ICE actually needs AFM. It's just more garbage brought forth by the love mutha earth hippies that's screwing up modern engines due to the "climate change" scam

By the way.... if anybody needs some carbon credits, just send me your cash and I'll put you down for owning your own carbon credits

The LGZ is not prone to Engine Failure
So, the ones that Jasper and Other ReMan companies would get their from would be mostly from wrecked vehicles.

What is most likely what did these 2 LGZ Engines in is what did another LGZ in on this Forum
A lack of Oil to 1 of the Banks of the Engine
It appeared to be a bad oil return on that one
The 1 Bank was Clean and the Other had that Glazed Burnt Oil Look

The AFM in the LGZ is nothing like that in the V8's
At some point you will have to realize the facts
