Getting a new engine for my 08 Silverado

[2050z]

Truck engine lasted almost five years. 160K miles and the #6 cylinder lifter has gone out. After a lot of research it's a known issue. GM won't cover the cost to fix this mess. AFM causes an oil consumption problem. Which in turn causes a whole bunch of other issues. My engine is 5.3L

I still love this truck so I am getting a refurbished engine with a 3 year / 100,000 mile warranty.

I've heard that this was an issue on some of them
Does it make any difference on what oil is used vs life of lifters ?
Sorry to hear it happened to yours
Hopefully your new engine will give many miles of use

Sorry to hear brother. Im hoping mine lasts 3 more years

04 5.3l with 230k on it. I get a little nervous each trip to the deer lease.

Be sure and have the AFM disabled or you will have oil consumption problems again sooner or later.
When there is no fuel into the cylinder during AFM the cylinder has no combustion pressure to keep the rings expanded. The cylinder is just acting like an air pump and will suck oil up past the rings on the intake stroke aided by the crankcase pressure. Probably one of the stupidest things GM ever did IMO. AFAIK the AFM is not a required part of your emissions system.

Regular oil changes with Mobil 1. Doesn't matter what the drivers used this AFM
is a piece of junk.

Several have mentioned getting a custom Tuner and turning it off.

Went through this just before Christmas, but it was on an 08 with the 4.8l

I decided to replace it with a Ford.

Fwiw- I got $2500 for mine from a wrecker in its non running state

I got lucky on my '10 with 4.8. Had it covered under warranty with just days left.

Anybody have a tuner for an 08 Chevy?

My 3 5.3L engines were great. However, I got rid of every one of them once they started to burn oil. All of them made it into the 160k area.

Theres an afm delete called range, it basically just plugs in the obd port and your ready to go. If your looking for a tune ide look real hard at blackbear performance, all they do is gm vehicles and can really wake a 5.3 up.... that is what I got done on my 2014 with a 5.3
