08 Tahoe 5.3L DOD/AFM lifter delete time?

[cmbWarEagle]

Which engine does your 2008 have? I know you said 5.3, but which one?

Some folks change the oil pump when doing this and of course the timing chain. Some use an LM7 or LS3 or LS6 or the GM Performance 88958775 camshaft. In my 5.3, an LC9, the LM7 cam is smaller while the LS3 is a Gen III equivalent. I've read from folks who like the LS6 in trucks, it's slightly bigger than the GM cam.

As for me, I'd like more torque down low where I drive most of the time. I rarely hit 4,000 rpms and usually under 3,500 with 3.42 gears.

I read that a guy who does these every day has it down to 3 hours though most folks do it in an afternoon.

New member so I apologize for beating a dead ***** but....Have the opportunity to pick up an 08 Tahoe LTZ, with 140,000 miles for 11,000. This dod/afm situation has me a bit concerned. Should I turn and run?

No, just prepare for it. Could last 300K, could go tomorrow. You can electronically turn it off and or physically remove it. It's also possible that it was rebuilt already with the improved parts; check the service history if possible ahead of time.

Not necessarily. If it's really clean and $11,000 is a deal, you may wanna jump on it if you like it. I bought my '08 LTZ almost 2.5 years ago with 147,000 miles on it. The $15,250 I paid was a pretty solid deal compared to what everything else in much worse condition was selling for. It's currently at 192,000 and runs smooth and strong. I had the AFM disabled through a tune almost a year ago. I get a lifter tick for about 3 seconds on a cold start, but that may not even be AFM related.
