I didn't realize they made the change when I bought my 16. Was a little missed when I noticed they lessened the warranty a few weeks after buying the truck. 90k miles is a lot for a 15. Must a lot of highway miles. Are you the original owner?

Yes Im the original owner, I used to travel a lot (about 45k miles a year) for work, lots of highway miles. Luckily I no longer put crazy miles on her

Cam shaft and lifters was the initial prognosis, they are doing a full rebuild including gaskets etc..

Did they happen to say what the root cause was?

As far as why it broke? No

[Cwildman]

Ya, I'd be curious. That's fairly low mileage.

Sounds just like a sparkplug blew out

AFM oil channels get plugged up and starve the lifters of oil causing them to grenade. Was a common issue on the vortec engines but I thought the ecotec had remedied the problem...

[Colossus]

that's downright depressing..

I appreciate that response, is there anything that can be done to prevent or is it just inherent?

How long are your oil change intervals? What kind of oil filter do you use?

[sdeeter19555]

This is where a quality synthetic oil and frequent oil changes may not be a bad idea...

 

Sort of like some of the turbo cars, the passages coke up from high temps and long change intervals and conventional oil; use of a synthetic nearly eliminates the issue.

Your close to the actual problem and the solution is BG GDI treatments and you can do it yourself!

This is something you don't really hear about on GM forums but go to the FERD'S and it's one,two, three motors and yes some of the guys are on their 4th F'N motor thanks to Ferds novel ecoboost!

 

Sucks but GM will fix it and not play warranty games..

[Patriot78]

I change my oil religiously at 3k mikes, I'll have to check to see what they've been using, pretty sure it's a synthetic..

 

Would eliminating the AFM via tuning or range plug in help?
