I had 3:21's stock, and it felt quick...more like 8 sec 0-60 than 7, but that's quick for your average suv. I now have 33's and a lift so I went to 4:10's with an LSD and my Jeep now feels seriously quick for an suv. Seat of the pants has me estimating it between 6.8 and 7.5. That's good for some average sedans let alone a Jeep. That being said, it's not a muscle car, nor will every iteration(JKU, manual, 3:21's) feel the same.
You're exactly right. Years ago my cousin owned a 1998 Z28 with an auto. My 1994 Camaro had a few mods but nothing serious, and would run consistent 14.1s in the 1/4 mile. No, they weren't groundbreaking numbers, but I would smoke him every single time. What happened to these low 13s stock LS1s were supposed to be running?

Anyway, I'd been in my cousin's pig of an LS1, and then I'd been in seriously quick LS1s, all stock. No engine is going to run the same, plain and simple.

So, did I get a pig? Maybe I did. A Jeep is not a sports car, so I really don't care whether it's a pig or a "freak."

Honestly I am a little worried about spending close to 40k on a vehicle and having to wonder about that damn ticking motor thing.

Slower than most means little to me and if anything else it will make me slow down as I drive crazy now anyway. Going in to this purchase I think we all know full well the JK is never going to be anything other than what it is......simple and rugged off road fun and not a sports car by any means.
You're right about that, a Jeep is NOT a Sports Car by ANY means!

False alarm. CEL turned off this AM, but I took it in anyway. Evap leak, most likely from a loose gas cap. This would not be an issue if the state of NJ would just let me fill up my own gas...

On the bright side, I have my Jeep! And if I do have a defective head, I've bought some time before I need to get it replaced, so by then the new ones should be the only option.

Nothing in NJ law that says you have to stay in your car. If you think the gas attendants are that incompetent, stand outside and check it before driving off.

First time I've had an issue, so I never really thought about it before. You can bet I'll be checking my gas cap more often.

I will say this though... I lived in NJ most of my life and never had the problem. My man has had that issue and he has never lived in a state where others pump your gas.

I didn't know that. That stinks, I prefer pumping my own gas.

Regarding this tick... If there was a problem with a cylinder head and you hear the tick, wouldn't the tick get louder as you accelerate? Please only answer if you know for sure. Rather stay away from opinions. Looking for a mechanic or knowledgeable person. Who knows for sure. Thanks guys.

Just because there is a law doesn't mean you can't do it. I pump my own gas 3 times a week, every week.

If a station doesn't let me, I don't go back there.

In Oregon, if a station gets caught letting someone pump their own gas, they get a huge fine from the fire marshals. You won't find many that will let you. Bikers get to because ABATE got an exception passed, but even they technically have to wait for the attendant to hand them the nozzle.

Personally I don't mind staying in the car and letting someone pump my gas. Rains a lot in Oregon.

Noticed the tick last night when my wife went to reposition the jeep in the garage for me as I was installing new bumpers. LOUD. Just checked and quickly found this thread. Mine's an early 2012... Think the build was sometime in October. Got about 6500 miles on it. Subscribing.

Sorry about your bad luck, Richard, but you sure are not alone. Here's a link to a poll I started about the problem and as you can see 50 out of 176 people who voted have the tick and 23 more have confirmed head problems, not just a tick. That's a total of 73 out of 176. There are 80 people who seem to be OK for now but have not reached 10,000 miles on their Jeeps yet. Some of these folks could also end up with problem.

Ticking

I have a 2012 Jeep Wrangler Sahara 2-door with the Pentastar engine and 5-speed automatic with 3.21 gears in back. I purchased in October 2011. I have a little over 5,000 miles on it. I first noticed the ticking at about 2,000 to 2,500 miles. It is fairly loud when you are near a wall or another car.

I do not have any codes or lights yet, as it runs well and I get 19-20 miles per gallon on mixed driving. It is sluggish when cold, but when it warms up it is fine. That has been the case since it was new.

I have an appointment with the dealer on August 8 for an oil change and I will have them document the ticking, which seems as it is coming from the driver's side. I have also put in a claim with Chysler Customer Care about this for future use.

I'll wait until a light comes on to get it fixed. I'd rather have a correct head. Other than that I like the Jeep.

New to this forum. I have noticed a "tick" in my Rubicon for some time but thought it was normal. Then I noticed it getting louder so called the dealer and take it in today. Then I searched and found this thread and damn its long but has a ton of good info. Build date 1-12, 2800 miles, 6 speed manual, runs fine but loud tick. I'll post after the visit.

I've got the tick, and from what others have said about the sound, it's pretty bad.

Ok, so the other day I was at a drive thru, and could hear it very well. I put the tranny in neutral and revved the engine once, prolly to about 4 or 5k rpms. The tick stopped. Of course it started again the next time I drove, but every now and then revving the engine appears to silence the tick. What does this mean??

My guess is increased oil pressure buffering whatever the heck it is that is otherwise ticking.

Let me clarify: Revving the engine in neutral silences the tick for the rest of the duration of my driving session. Ticking didn't resume until the next morning when I started her up and went to work. But again, another beefy rev and most times the tick goes away. Would a bad head behave like this? - I am not mechanically inclined.

The oil drains out of the valvetrain after sitting all night. When you start the engine, the oil is pumped up to the valvetrain and the oil pressure keeps whatever the heck it is from clattering. You keep driving, maintain the oil pressure, you don't hear it until the oil drains down to the pan again.

Yes, but oil pressure is not keeping ticking engines from ticking. Not sure what you're getting at...

Mine ticks 100% of my time spent driving, idling, etc. If the engine is running, it's ticking. Unless I rev the engine, that is, and then it seems to go away temporarily.

Well I went to the dealer and was told the following:

Sounds normal - ticking could be caused by:


- normal lifter/injection sound
- the warm weather thinning the oil
- the fact that I have a lift that raised the Jeep so the sound is closer to your ear (I particularly liked that one)

And not to worry cause - the engine is really sensitive so any problem will throw a code

So I'll drive it till it codes or blows either way I have the warranty.

I see. I thought you meant it just ticks at startup after having been shut down for a while, and once you gave it some gas after startup it went away.

As for the oil pressure deal, that's a question of clearance. If you have a little too much clearance, the pressurized oil can cushion it so you don't hear a noise. If you have way too much clearance, then no amount of oil pressure is going to shut it up.

Kind of like rhoads lifters, or how guys used to throw 90 weight in the crankcase to sell a car with an engine knock.

How long does the sound go away after you rev your engine?

So you only lifted the engine? That is the only way that the distance between the cabin and the engine would vary.

For what it is worth... I have a friend that is a Chrysler tech so I texted him about my ticking. He said he has 4 3.6s in the shop right now (didn't say models). He said they are all over 30k miles and are all rental or fleet. He said that the tapping is not directly related to trouble. He did say mine was louder that what he was seeing after I sent him a video. What he has been seeing is a CEL with a misfire on 2,4 or 6....checks compression, if low replace head, although he says it is an exhaust valve leaking. He also said that the replacement heads are identical to the ones they are removing and he has heard of possible reengineered heads by the end of the year. Like I said...for what it's worth, not sure.
