Your thoughts on the 5.7 hemi tick

They (all makes) all have their quirks. Doesn't matter if it's a ford, gm, or chrysler product. Having driven late model versions of them all, and owning 4 late model hemi's ranging from 130-251k Miles, the hemi's are far from the worst. The gm "Dod" engines, and the ford cam phasers, are as notorious as any hemi "lifter problem". The tundra is, and always has been, hideous.
I am or maybe I should say “was” the proud owner of a 2011 ram 1500 truck with a 5.7 hemi.
I’m so disappointed in the 5.7 that I feel maybe I should buy, and I hate to even think this but maybe a Ford!
I’ve been bitten by what I am being told is the hemi tick. (And my motor is not making any tick at all) I had never heard of this until I had my CEL came on 3 weeks ago. Code was for cyl 5 misfire. Bought a coil pack and plugs and replaced them that night. Next day light on again. Cleared it and again next day back on. Bad coil pack? Switched #5 with #1. Next day cyl 5 misfire. Got on the web, googled 5.7 cyl misfire and found there is a major issue with the hemi.
Finally pulled valve cover off yesterday only to find rocker arm not moving much on #5 cyl.
Sick to my stomach.
How can this be happening. Only 60k miles. Driven softly since I bought it a 30k miles.
Looks like I’m buying a cam and lifters or am I? Seems as tho there’s a supply issue with lifters.
Ok, so now the part that I really need help with. Help me understand the 5.7 engine.
I know this is a early “A” group/forum but I’m hoping someone here can explain a few things. Mainly the timing procedures. The phaser. The reflashing if it’s not a stock cam. What keeps this from happening on the new parts I end up buying? I was using Mobile 1 5-20 but so many are saying it’s not good enough oil lubrication that I should be using redline or royal purple. By the way I only used the mobile because that’s what the original owner had always used. I’m thinking once this is all fixed going to brad Penn 5-30 because it has zinc.
Sorry for the negative post but the mopar people have really let me down with this cam/lifter design. Plus I don’t understand these modern engines and computers.
Any help would be greatly appreciated.
Thanks, Rod
Any indication that it didn't just pop a lifter diaphragm? I get smoke=fire, but a lifter failure is more likely than a flat cam at that mileage.
