6.4 Hemi Ticking

Take a look at my thread, I picked up a 5.7 that had been pulled out of a 2014 Ram truck due to a ticking noise and misfire codes. Turned out to be a failed MDS lifter, roller wheel gave up the ghost and trashed itself and the cam lobe. In my case it was a bit easier to notice which one had failed because it also bent the pushrod, otherwise you'd need to pull the heads to get to the lifters.
