2018 Ram 2500 Knocking

[rayelee]

I have a 2018 ram 2500 6.4 hemi knocking I think I'm not sure I did a lifter replacement and relapped the valves for my hemi tick to go away now for a new noise to come up

I have a video attached

Questions: Was the engine quiet initially, after doing the work ..like driving it around a few days/weeks? Or did the noise occur after start-up (after the work)? Did you replace or do anything with the lifters during the work?

I guess if it were my vehicle, I'd try to isolate the sound better. Usually bottom end and rods will knock more under different revving conditions (there's videos how to determine). I'd probably get a stethescope or wood dowel (to the ear) -- I'm a wood dowel guy ...and probe around the engine (safely) and try to isolate the sound before pulling off the valve covers to have a look-see.

I replaced the lifters, and the noise started at start-up. I will be getting a sethescope to help me isolate the sound better

How long have you let it run? What's your oil pressure look like (cold/warm)?

You're not alone:

5.7 hemi new lifters still ticking need ideas

I have a 2013 Ram with 5.7. I replaced cam and lifters due to the “hemi tick”. The amount of noise was better but not gone. The back passenger side still has a consistent tick. I took it apart and replaced all push rods and rockers with new ones. It still ticked. I just went in and put new...

What head gasket did you use?

Help! Lifter knock after lifter and cam swap

Just a update. Removed the heads had them machined and washed. Checked the lifters and all roller bearings look good. No visable damage to them and they roll well. I also used a camera and looked at each camshaft lobe and it looked fine, no denting visable. The truck only ran a short time so I'm...
