2014 GM Truck Recall

[ruffdog]

uh-oh......are all these cylinder cutout engines oil pumpers?

most are not

 

[DeereMann]

right - i don't recall an endemic oil pumping issue on the HEMI's - they didn't point oil jets at the rings, if memory service, unlike GM on the 5.3L. The 5.3L oil pumping / consumption is well known.

 

[ruffdog]

The 300 we had was a 3.5L v6 that was not a DOD engine. It ran good but just used lots of oil. Most people do NOT have issues with AFM but, a few do.

Mercedes used to cut off one cylinder bank of their truck V6 diesels in the 80s, if i recall correct... Just three of the injection elements of the engine would have a different helix cut so that it would idle on three and the other three started as soon as the rack moved away from low idle position.

We have had seven to date, 5.3 and 6.2. None used oil between changes. 4.3 V6 just got rid of with 180,000 used a quart every 5,000, and it ran on all 6 all the time.

I have one of those too...396 with 4:11's..Not bad on gas until I put my foot in the carb..Odd that gas guage never came close to where it was after.

The first new car my dad bought was a 69 SS 396 Chevelle. I remember it well. I can still hear the rubber burning and the dual exhaust singing. My mom would drive it during the week to get groceries and her hair done. Dad would load me in the passenger seat and launch it at the stop sign at the end if our street on Saturday after working all week. I would laugh till my sides hurt like any young boy would do when their dad did something that cool.

I brought a 69 SS 396/375hp to my dad when I was 16. Said I was going to buy it for my first car. Good not great shape,#s matching auto air. He is a muscle car guy. He laughed his butt off. "Son, that car has more power than you have sense. Not happening. " The car had a little motor work done, probably 410-420 hp actually. Broke them loose at a 45mph roll.

My dad's was a 396/350 horse. His was an auto tranny and factory air. I THINK only the 4 speed manuals got the 375 HP. I love that body style. Wouldn't mind having one taking up space in my 3rd bay. The only thing he changed on the car was the wheels. He replaced the factory SS wheels for 15x8 Vette Rally's w wide bands and flat center caps. Still like those steel wheels on em today even with all the alloy aftermarket options.

My dad had a 66 396/350hp, 4spd. Marina blue, black vinyl top black interior. My 70 is green on black. The 66-67 were my favorite body styles.

Well I have 2007 Silverado with a 5.3 AFM engine that uses 1 qt of oil every 2k miles. GM's response is to claim that is acceptable oil consumption. Don't pat them on the back too hard.

Your truck can be reflashed with EFILive to block out the AFM (active fuel management) logic. Your oil consumption will be reduced. EFILive - Home
