Anyone else have a ticking/nocking sound at startup?
It only lasts for a second, but when I crank up my 3.8 JK, the engine almost sounds like it's dry and I can just hear this tick-tick-nock and it all smooths out within just a few cycles of the crank. anyone else notice this, or just me. The oil level is fine and I have no clue as to what it could be.

It's an easy fix to swap out the filter for a new one. You don't have to drain the oil first. Just be prepared to catch the oil from the filter.
One thing to do is to turn your key to on without starting the engine. Let all the lights cycle through. Then start the engine. Watch for a possible brief flash of the red oil-can idiot light (low oil pressure). That's a telltale sign of a bad ADB valve.
Search the forum, it's a common problem....

It could be your oil filter has a bad anti-drainback valve. Does the sound mainly occur when the jeep has sat for overnight or longer?

It's been 3000 km since changed.
Where does it go?
