Hello, I own a 2001 Dodge Intrepid with the infamous 2.7litre engine but mine has 150,000 miles on it, yeah! I started it this morning and it started knocking. I thought it was because it hadn't been run in a few days but the noise remained after warm up. I put in Lucas Oil stabilizer and it stopped for a few seconds but returned. The noise is on the passenger side top just under the valve cover (at least it's very clear there). I haven't noticed a loss in power although I did park it pretty quickly. I really want to squeeze a few more miles out of it. Does it sound like a lifter problem?
It is a knock and not a tick like a injector.

The timing chain is loose and slapping around. Getting 150k out of this engine, consider yourself lucky!

Thank you very much for the reply. It just doesn't seem like a timing chain. I was actually going to pull the valve cover off and decided to start it again. It knocked for about a second or 2 but then smoothed out and stopped. Now it only knocks when it first starts for a couple seconds and stops. Maybe the Lucas oil worked. I guess no more long trips in this car!
