2013 Ram 1500 5.7 started making funny noise

Didn’t get it, it sounds worse now.

Looks like I’ll be breaking it down again.

Use a ratchet on the shafts,and snug them down in stages working in a circle from the center out.Don't wind one bolt down at a time,otherwise you can distort/bend the rocker shaft

We did that.

Really at a loss here, as we were very careful to torque everything properly. I guess we tear it back down and start inspecting everything.

I have three weeks worth of work to do this week with a house remodel of my own house that is supposed to start soon as well. Going to try and rent a truck or something and maybe start back on this next week.

Really feels like a gut punch for sure.

Just got the right head pulled, the new lifters seem fine. The rollers spin freely and bearings in them all seem fine. Working on the left head now. Pushrods are all fine. Trying to figure out why we still had a bad tick. Is there a way to check the rocker tube to make sure nothing is bent?

With-out totally disassembling the shaft,about all you can do is give it the look see with the old eyeball/You can lay it on a piece of glass and see if any of the rockers don't sit as flush as the other rockers do.Even the OEM lifters can have a bad one occassionally,use a pushrod and use it to depress the plungers in the lifters and make sure they all feel the same

So we took the heads over to a machine shop where I know the guy and he said I need new exhaust rockers. He’s also going to surface the top of the valves. He thinks that’s what we were hearing.

He said the rocker arms were worn and looked like they were hammering the top of the valves.

With taking material off of the valve stems, you may need a thicker head gasket to compensate for the material you machined off of the valve stems, you're going to have more ticking with the valve stems being machined, if they are that bad the valve should be replaced.
@Burla I think as you the flex plate is where the noise is coming from.

Machine shop guy said what he’s doing shouldn’t affect the compression so I doubt I would need a different head gasket? He just wants to see new rocker arms in proper contact with the valve stems. I would think he’s taking off a minimal amount on them.
