Engine ticking noise
 

Hi there,

I have a '05 unlimited TJ with 79000 km's on it with a six speed manual. I've noticed that when she starts up (particularly in colder temps) there is a ticking coming from the motor. I replaced the belt thinking that was the issue but it still ticks. Next oil change I used on of those "engine clearer" systems that didn't help either. I use nothing but sythetic oil... any thoughts??

I have the same ticking, but i have a 2001 with 200,000km's. Goes away after 5 mins once the engine warms up. Ive heard from other people its a common thing for jeeps. Not sure what its from.

Sounds like Valve tick/stick. Try a flush, Then Higher grade Oils.

I have the same thing in my 2004 4.0 l....Just going to drive it, it won't harm anything. It's your typical amc engine.

What weight Oils are you using?.. The ticking seems to be a valve and it stops ticking due to the oil heating up. Got video at all?

1. Use a quality oil filter with a reliable filtration media and quality anti-drainback valve (No FRAM, MotoMaster, STP, quick lube no-names, etc)
2. Experiment with quality oil, keep the startup viscosity low (eg 5W-whatever)
3. If it's a 4.0, its probably your lifters
4. Keep up with oil changes and drive for 500,000 KM
