Ticking noise until warmed up

[arcstarter]

My 2019 Cummins HO seems to be ticking until fully warmed up, CP4 recall was done a month or so ago. Anyone have an idea of what the noise is?

I've heard that there is a TSB for lifter noise on the '19-'20 trucks, I would check with your dealer to see if it applies to your truck

I have the same noise, it's annoying

My wife thinks I only have 3 guns

The only TSB I could find was the one for proper oil weight for the 19+ trucks with the hydraulic lifters, I have used 5W-40 T6 since first oil change

I haven't done the first oil change, I will get that done sometime next week

I have the same ticking noise. Is the AC on when you are hearing it? It seems to stop when I shut off the AC and comes back when I turn it on.

I just got my truck back from the dealer. They changed the AC compressor and the noise is gone. I will be listening for it to come back.

mine is there even with AC turned off, but gone once engine is at operating temp

I had to take it back to the dealer, the refrigerant leak out of the system. They charged it and now I noticed it has the ticking again. Maybe it’s a pulley when there is a load from the AC.

Did you ever find out what the tick was?

I did not, went away in the winter and hasn't been back, did see a video on facebook that a guy might have found it to be the belt tensioner. Same noise and when he put tension on the tensioner it went away.

I saw that one too. Sounds like the famous typewriter tick. Many report it starts after a oil change and what that has to do with the tensioner is beyond me.

My 2018 ram (77k when traded in) made ticking noise like that from dog filter. My 2022 ram (27k so far) does same every now and then. Both trucks run CP3 pump. Never had issues. My experience. Hope it helps.

I’ve got the issue started after oil change. Dealer tried to tell me needed an oil additive. I bought it out of Germany. Still tick, took it back they said it was the DEF injector. At another dealer now and they said no way is it the injector.

ticks when cold start and goes away but today it started doing it the entire time especially with small throttle burst. When the ac is on or off. Below is the link to the sound with AC off. As the fan is loud here in summer az.
