Does The 6.0 Have The Lifter Problem?

[seamonster]

How many of you have the 6.0 in 1500's with lifter/oil burning problem?

 

I know there are some 5.3's but any 6.0's?

The 6.0 doesnt have afm which is the supposed cause in the 5.3's

My 6.0 has AFM. For the time being anyway. Its getting taken off when its tuned

My 2007 1500 has the 6.0L with AFM. I would like to know this answer too.

My previous truck was an 07 Vmax with the AFM... I did turn it off, but I had no issues with it either way. And zero use of excess oil usage or lifter problems. I traded with 54,000 miles.

No lifter or oil burning issues here.

Ok I know nothing about the 6.0 but its kinda funny that there arent really issues with the 6.0 but there are with the 5.3. Kinda makes me believe its not AFM related

111,000 miles with no issue on the 6.0. I've had the AFM disabled since the 90,000 mile mark.

Gee,I've been saying that from the beginning

[MS3DALE]

Oh and for the record....no issues with my 6-liter.

AFM (Active Fuel Management) and V8 Engine codes: RPO L76, L94, L99, LC9, LFA, LH6, LMG, LS4, LY5 or LZ1

[nickvrebel]

for those blaming it on AFM, the LSx series motors, which includes all "small block" V8's made by GM from 1999 forward, have been known for oil consumption since 1997 when the first motor went in the Corvette.

My 2008 has this problem. It does not use oil but it has the cold start lifter noise. My dealer has replaced the lifters twice. The second time there was noise all of the time and they also replaced the cam, push rods, rockers, and oil pump. It still makes noise after all of that work. The problem first showed up at 3k miles.

Maybe we are onto something here. Maybe this was just a bad batch of the 5.3's
