Just bought an 08 GMC with a 5.3 with active fuel management. It has a bad lifter which doesn't seem to be terribly uncommon.
My question is whether or not to leave the afm in it. Cost is probably $100 more to just replace the cam and a few other misc parts and pay someone to turn off the afm in the pcm.
Seems to be a lot of discussion online about issues with the early afm trucks including lifters and oil consumption. It would obviously be easier to just drop a new set of lifters in and go, but I'm wondering if that's the best course of action.

I did keep everything I replaced for the day I do want to restore her to showroom condition.
