Having the lifters collapse and stay collapsed to where a cylinder head removal and lifter replace is the issue. Also rounding off camshaft lobes is another big issue with the AFM lifters.



Never had a problem with mine. If you are concerned, then get the 4.8L or the 3/4 ton with the 6.0L.

you are very lucky. I am a mechanic and damn near every customer of mine that has this motor has had the lifter collapse. shite, even 3 of my fellow employees have had the post 07 model 5.3's and all 3 of theirs have had the issue. Swapping out the cam and installing LS7 lifters and deactivating the AFM is the way to go.
