Oil Tick on a 4.0L
Hello all,
I have an 2004 WJ with a 4.0L 6 banger and am starting to get a ticking when I first start the engine, but goes away in about 5 to 10 minutes and is fine after that. IS my oil pump starting to go?

If the ticking comes from the head area, its most probably a hydraulic valve lash adjuster which is making the sound.
