Silverado 5.3 update 12/11

[olds307 and 403]

Interesting these LS with DOD have these issues, do the newer LT motors? The Hemi's also have cam and lifters failure issues, better now but still occurring occasionally. It will be interesting to see if the 5L Coyote has failures now that is DOD across all lines. There is enough cam phaser issues in Ferd's.

They do the same crap, any of them with it.

Awesome. /s

I’ve got one of the range disables. Might just plug that in until I see or hear something funny going on.

The service guy Im dealing with has used them in his own trucks and told me I should consider buying one.

disable only, still has AFM parts
lifter #7 got jammed. tore down the top, inspected with flashlight and camera, didn't get twisted and lobe looked ok, knocked the lifter loose with pushrod and hammer, connected computer and Disabled AFM. been running fine for the last 20 months.

That must be lucky #7 cause it seems like that's the one to go. My '08 had the #7 fail & basicly wiped out the engine. The garage that did the swap just had a Avalanche in a few weeks earlier with #7 failure that had to be a complete engine swap.

I'm like the 4th or 5th owner of my truck so I don't know if it happened before. bought it 174k, lifter failure at 185.7k miles

looking at my notes (I keep detailed service notes), I noted that Oil Life from the computer said 5% left after the fix and was having low oil pressure at around 20psi. did an oil change the day after fixing it, drove 3 miles back to the house and had a steady 40psi. idled for 5 minutes after parking and had a steady 30psi

Is this conversation relevant to the 6.2, or just the 5.3? Asking for a friend

yes they do

I feel like the diablo tuner adjusted the shift points and the throttle response is slightly improved. The big reason i got it was for the DOD deactivation.


One annoying thing I'm dealing with now is a slight oil drip from around the oil filter adapter. Lots of people have said its probably the gasket between the oil cooler line and the oil filter adapter. Anyone else experiencing this?


Again apologies for hijacking this thread lol.

Yup that's common.

Thats what im hearing. The oem gasket was a 6 dollar part and a low level of *ss pain to change or so i hear. Will do it once i complete the Jackson Pollock in oil on my driveway from the drips. Its coming along rather nicely.
