Jeep Repair Problems? Ask a Mechanic for Answers ASAP
Hi C Benson,
It sounds like you've got a lifter or two that are bleeding off, and yes I've seen several of them in the 03-04 year model. The bad news is I've never seen one correct itself, I've always had to replace the lifters. And some have even went long enough to wear out the cam shaft and damage the lobe(s). I've seen people use all different kinds of oil and lubes and they still end up replaceing the lifters to remove the noise. And it's not and easy job, cause the cylinder head has to come off to remove them. But I've not have one return after replaceing them, its always fixed the cold start ticking noise. Feel free to write me back if you need anymore information, thanks David.
