Wj UGG!!! Lifter tick? 4.0L

Well guys, got my exhaust installed today and it sounds pretty good for an inline 6 engine. Anyways leaving work today when I stopped at a redlight and rolled the window down I heard what sounded like a faint lifter tick. It was hard to tell though cause even when you barely revved the engine the sound is masked by the exhaust. This kind of stuff really bugs me even if it isnt the biggest deal. Jeep is a 2000 model with only 109,000mi on it and an oil change 1000mi ago, maybe 100-200mi less. Any tips on how to solve this if it still makes the noise in the morning.

The lifters can get gummed up over time. Use an oil with high concentration of detergent like Castrol GTX. What I did and the tick went away after a couple of oil changes.

I'd suggest you add a pint of Marvel Mystery Oil to the crankcase this will often clear up lifter tick and it won't hurt a thing if it doesn't.

After I seafoamed my '99 I6 the quiet lifter tick I had seemed to have smoothed out. Some people swear by seafoam, others say it ruins O2 sensors.

I say that provided you follow the written directions, you can't really go wrong.

Are you sure the tick is not an exhaust manifold leak? The fact that your exhaust was worked on and you noticed the tick shortly thereafter means it could be the exhaust manifold. Sometimes that can be mistaken for a lifter tick.
