just fyi here's your mds system, not the different lifter lifting patterns at the end of this...

If you are DIY-ing it, I would think the cam/lifter swap would be easiest and cheapest.
sounds not relevant now, buy mds system shuts down 4 cylinders and send more gas to other cylinders in the name of fuel economy, if you disable it all cylinders fire all the time. Reman engine is a lot more work as you need to remove engine and tranny, cam install is way less work. This is a great dyi cam instal thread, kind of a cam bible around here.
Could't hear the video but did watch it. From video it shows cam lobes moving while others are not? if so I'm not sure how that works. Are you suggesting that something could be wrong with MDS instead of the cam itself?just fyi here's your mds system, not the different lifter lifting patterns at the end of this...
I be damned if you didn't nail the diagnosis on this 1............LoLI was wondering what would happen if someone ignored the misfire code and symptoms after losing a lifter for an extended period.

Thanks for the link. I'll look through that thread. I've never done a cam swap before but have removed and installed engines many times. The truck belongs to a company (HVAC) that my son in law works for. So I guess it will be decided by them. If I do the swap what range would labor be charged?
Thanks
Well picked up a compression and leak down tester. Compression tested a little over 120. Didn't know when you engaged starter that it will continue to crank. So I was able to crank it over and look at movement of rockers. The #8 intake rocker movement was much less than others by about 50%. So i would assume its the camshaft lobe is ate up. Is it worth a cam replacement on it at 160k miles or put in reman engine?
Might want to look into a boroscope like this and see what the cylinder looks like

Have a 2014 ram 1500 160k miles with a 5.7 hemi with codes p0300 and p0308. I pulled all the plugs on passenger side and all looked fine except for the two in cylinder #8. I have never seen plugs get this bad before. Any ideas on the cause? I will post picture of the plugs any help is appreciated.

This will foul plugs long term if ignoring codes & continue to operate engine.Well picked up a compression and leak down tester. Compression tested a little over 120.
