Not sure why dodge dealer said warranty would be void. Valve lash is not covered under warranty, its maintance. Guess its a good thing you took it to somebody that had a clue.

That's an interesting statement. What does that mean? What is the low maint design? AFAIK, they're still solid lifters - that's why they need some lash. So they're not going to be self adjusting like a hydraulic lifter is.

Another question. When I adjust rocker arms on a gas engine, I remove all the spark plugs and turn the engine over with a socket on the balancer bolt. On a diesel, obviously, there's no spark plug to remove. So how do you turn the engine over by hand with that much static compression?

When I adjust a gas engine, I don't bother turning the crankshaft a certain amount, or adjusting exach specific rocker arm in a specific order. To complicated and time consuming.

Adjust the intake when the exhaust is halfway to open.

Adjust the exhaust when the intake is half way to closed.

That ensures the lifter is on the base circle. It becomes a matter of turning the engine by hand and watching the rocker arms move up and down. only takes a few minutes to do 16 valves. This procedure is recommended by Comp Cams.

But that's a gas engine. Would the same procedure work with a diesel? I don't see why it wouldn't. But then, there's a lot I don't know about a diesel engine.

Oh, and some one mentioned that the valve springs are kinda wimpy. That's a good thing. You need enough spring pressure to control the valve and prevent float at max rpm. Most diesel engine never see the north side of 4,000 rpm's. Doesn't take much to control the valves at that rpm.

Too much spring pressure reduces longevity. A gas race engine has about 450# of open pressure. But you have to replace those springs about every 20-30 hours depending on use. And you have to replace the rest of the valve train (gears, chain, push rods, rocker arms, camshaft) about every 60-70 hours. Too much spring pressure is not good.

Hey guys we just did this adjustment on an 04' Dodge 2500, Check out these YouTube videos I made showing the process.
Part 1 is disassembly, Part 2 is how to perform the adjustment itself, and Part 3 is reassembly. Hope these help
