need advice, motor ticking

i have a 2002 jeep wrangler x, with the 4.0 straight 6. we took it out riding today and after about 2 hours of driving around trails and backroads. it sounded like my lifters started tapping at low rpms and high rpms. but it would also stop tapping at low and high rpms it was random when it started or stopped. when i got home i popped the hood and listened and it sounded like it was coming from the back of the motor. the oil level is good, the oil is fresh and its synthetic. the motor only has 74000 miles on it. any advice is much appreciated. i need to know where to start looking. thanks!

Oil level good. Change the oil regularly?? Those are some causes. A good oil using recommended weight for your engine and climate. Try an additive there are many check with your local parts store.

The oil level is good I only run synthetic oil. It doesn't sound like its all the lifters just the back one or two.

Oh and the oil pressure is normal. I'm the 3rd owner of the jeep I've only had to change the oil once since I had it. The lifters started tapping right before I changed the oil. That was 3 or 4 months ago and it stopped it till now.
