Default Top End Ticking

My 2002 Ram 4.7L has a tick somewhere in the top of the motor, it sounds like a lifter if it had any- do the SOHC heads have any issue with valve lash issues or cam slap? The motor has 99K on it, and I rebuilt the entire timing group (3 chains, 6 sprockets, 4 tensioners if anyone's counting) with a nice Cloyes lifetime warranty set 2 yrs & 15K ago. Tick noise settles in below 1700 rpm but disappears above that. It sounds nothing like chain slap, but an actual "tick" like tapping on something with a screwdriver. Motor runs great, no trouble codes, no burning oil, no smoke, no emissions issues at all. Dealer says busted timing chain tensioner but from my experience that makes no sense. Anyone have something similar or heard of it? If so, what was the finding? Thanks!

I have a sosge ram with a 4.7 and had the same problem. I had number 6 and 8 rocker arms come off and didn't know how. It was due to sludge build up. Also dosage usually only like champion spark plugs. That. I did a oil flush changed the oil filler tube got new rocker arms and lifters and problem went away

Mine is ticking alittle for 30sec or so on startup. I think this is fairly normal. Keep oil changed reguarlly with good oil. These engines will sludge up with bad maintinence. If you have a rocker come off like the previous poster mentioned it will misfire and throw a code. These engines do not have lifters (per se) they call them lash adjusters and they can get sludged up and need replacement. I am running some Seafoam through mine to see if it stops the ticking. then reg. oil changes with 5w-30 oil is what is recommended. I always ran 10w-30 but will use this new weight and see how it goes. Just purchesed the truck so I dont know the history of it. It has 103,900mi now and hope to head off any problems in the future.
