2011 with 5.7 Hemi. 156k miles. I disabled the mds last year (with Superchips tuner) due to a noise when it engaged 4cyl mode. Read that it could be cam phaser.
I recently heard tapping sound so pulled cylinder head and found seized lifter bearing. I’d like to get parts on the way ASAP but not 100% sure on what to get. I did consider a cam swap while I’m at it but don’t want to complicate things. I’m already happy with the performance of the truck with 3.92 gears so my priority is reliability. I am planning on replacing all lifters. Should I get all “non mds” lifters since I have it disabled anyway? Thoughts on hellcat lifters on stock truck? And what about the mds delete plugs? Any need to pull the mds solenoids since I’ve already disabled with tuner? Ok to reuse head bolts? I’m guessing new timing set would be recommended as the condition of the cam phaser is questionable.
Thanks in advance for any help offered. I know that’s a lot of questions but I’m sure there’s one or two people on here that have been through this before.
