Default Guess that sound! - "Ticking" from engine, just lifters?

I recently replaced the oil in my 2001 XJ Sport (189,000 miles). I went with the Rotella Triple Protection 10w30 and a Motorcraft FLA-1 filter. In my previous OCI's I'd used regular old Valvoline 10w30.

I'm getting a ticking now:


Is this just a lifter? It isn't going away after the jeep gets warmed up. Should I try a different filter or oil? Is it anything to be concerned about?

I know this is probably a pretty basic question, but unfortunately in my daily social circles I don't have a lot of good resources for asking a question like this. Thanks for your help!

If it started when you changed oil you can almost bet it has to do with the oil change. Did you increase weight? Rotella is some good stuff though

The lifters could just be happy they got some new lube seriously though that's weird that it wasn't doing it before an oil change now it is.

That sounds like one you could pin-point with a section of hose held to your ear.

Good one! At a loss. Nothing touching the fan?

I love it when my jeep is happy when it gets attention.

I went from 5 to 20 and I was getting some clicking/ grumbling,then went to 10 and it was happier

judging from just the video, sounds like a rocker arm/lifter issue. might pull the valve cover, and check your pushrod lash. new oil could have also freed up some engine debris that is clogging a pushrod, or lifter..

While I am new to jeep and the inline 6 motor in general, I know motors..lol SBC guy for years...

Id start by draining that oil, and using the same stuff you used before. see if thats the culprit. sometimes also when you drain your motor really good of all oil, you will get a lifter tap, but shouldnt last more than a minute or two. then the oil will pump back up into the lifters and stop.

could be simple valve lash adjustment, or could mean replacing lifters..

or, second guess and this is kind of a stretch would be your flywheel bolts are loose. but usually sounds more like a tractor/diesle noise coming from the rear.

What happens if you shut the engine off for 30 seconds after starting? Does the tap quit upon restart?

Sounds like a purge valve solenoid. Sure it's internal to the motor?

I think that solonoid is on the firewall, you might hear it inside the cab as well.

The rhythm (frequency) sounds too fast for a lifter. What was your idle speed in that video? Does the frequency increase with rpm? Check that purge solenoid. Is your check engine light on?

Fixed. OCOD always needs to be eliminated as a problem:

Actually, yes, it's been on for about 18 months and it's throwing a 0455 (small leak in the evap. emissions system) so what you guys are saying would actually make a lot of sense. It was idling in this video, so low RPM. I guess it's time to finally get to work looking for a leak in the system! I'll start around the canister.

No OCOD for me! I've gone back and forth between the Mopar and Motorcraft FLA-1 filters.

You guys mentioned to check the valve lash, what is that spec anyway?

Basically, forget that, it's for solid, not hydraulic lifters. Tough to measure a gap that is not there and controlled by oil pressure.
