Hay Guys, you may have a collapse hydraulic lifter, there's no valve lash adjustment on the rocker arm assembly but you will be able to see a dead rocker did you replace the push rods
how's your oil pressure you said you replaced the pump, did you do a compression test these are a few ideas from the old days, thats on of the reasons I came back to Ram, sick and tired of the cam phasers duel timing chains and tensioners had my share of problems
If he has the valve covers off and can either get the engine to run enough or turns the crank by hand, he could watch the rocker arms go up and down as well as the valves. If it’s a lifter there should be a big difference in the distance it goes up and down compared to the good cylinders.
