In other words, engines that are over engineered to save fuel are far more wasteful than any engine just made to use all the cylinders all the time. The cylinder deactivation engines last decades. The cylinder deactivation engines are failing in just a few years. These new engine do not save money.
I just had a DOD lifter fail on '07 Tahoe, about 2 weeks after I bought it, no noise or anything, just a miss on cylinder 4. When I pulled the valve cover sure enough the intake valve isnt opening, mysteriously it also had new, no name, junk looking coil on cylinder 4, so I suspect it may have gave the previous owners some trouble at some point and they tried that first, and then possibly doctored up the lifter somehow. It was runing like a top prior and I put well over 1000 miles in the short time I've owned it, it probably would have held if the DOD was tuned out afterwards.

Month ago!? Cause your job is to rip people off
Check this out
I was a GM guy till I bought a Ford F350 in 2004 GM has completely lost it's quality
All to get one more MPG and raise the price of the truck. Excellent.
You got it wrong it wasn’t last month
It just started not too long ago
Wait that long and a new engine is the only thing that's going to fix it for the long haul

Damn homie did you say 8 hours? That means 8 days for me lol
The best way is to replace the lifter with the spring on them. To the regular lifters that is in the GM sports cars Corvette SS Camaro Cadillac V
