I have a '13 JGC 5.7L with 70K miles. Noticed the tapping yesterday while in a drive through getting a coffee. I assumed it was from the car behind me and drove off. I pulled into another parking lot with a 90 degree right turn and it felt like I had flat tires. Hard turn. Heard ticking again and knew it was me. Noticed power steering fluid was low so I topped it off.

Now ticking starts at startup and goes away in 15 seconds or so. Sounds like from under car as opposed to in engine compartment. It makes the ticking sound at start up hot or cold. It is 15 to 20 quick sounds then goes away. If I put it in reverse, neutral or drive it will do the same. And when in gear I turn the wheel to either side I get the same sound then it goes away until I turn the wheel to the opposite side. To me it sounds electrical, but who knows. Video for the sound is attached.

We had about 12" of snow yesterday so not sure if its related to that.

I have not driven it since.

Any thoughts?

I went out today to run my scanner to see if there were any codes. All clear. However, with the key in the on/Accessory position I get the ticking, clicking sound. So not lifters, or a belt, or a pulley.

The plot thickens here. So not sure if it is a power steering pump or something else.

Does this help solve the problem?

Sounds like the Evap Maybe pop the hood and then turn the car to ON. evap is near the A/C line i believe. Just narrow it down.

I will check that out. Thank you for the suggestion. For my own understanding, what is in the EVAP that would click like this? Is there a switch or solenoid? Also is there a fuse I can pull to see if the sound goes away?

Thanks again,

Hello RDHDZ3,

If you decide you'd like to get this looked at by your Jeep dealer, please let us know. We'd be glad to help throughout that process.

The evaporative emissions system has a solenoid purge valve in it. When the conditions are appropriate, the computer opens the valve and allows the engine to suck in all the collected gas fumes in the system and burn them, thus purging the system for the next time you park the car and fumes start to build up in the fuel system that must be stored.

This purge can happen anytime, and the solenoid valve opens and closes rapidly during it. If you let in too much fumes you'll interfere with smooth engine operation. So it can tick while its operating. If its bad it can tick worse.

BUT, there is another possibility. Valvetrain noise. It will make a ticking racket and its very bad for the engine.

Before I panic you, your description sounds more like the solenoid valve.

The engine has a complex set of linkages between the cam and valves, to open the valves, there are hydraulic lash adjusters (lifters) between the cam and linkages, to take up any space. They require oil pressure to work properly. If they are not working properly, they will allow some space to develop between the linkages and the speed the valves open/close, just a few thousands of inch gap between them will result in forces the same as pounding the ends of linkages with a hammer, thus the pinging/tinking noises. When you first start the motor, oil pressure has to build up for the lash adjusters to work.

The oil filter has an anti-drainback valve in it, it prevents oil from draining out of the motor and back into the pan. Thus the motor's oil journals remaining filled with oil allows the oil pressure to build in a moment and prevent any valvetrain noise from coming. Perhaps a worn motor might have a moment of valvetrain noise after start up. Here's the thing, people don't realize when they use really cheap oil filters, the one that comes to mind is painted orange. Some are made with cardboard end caps, while true those cardboard endcaps are impregnated with plastic to prevent them from coming apart (it doesn't always work) they make for a very poor sealing surface for the anti-drainback valve (if you look how an oil filter is constructed the anti-drainback valve seals against the end cap of the filter element) and thus don't work well. I have a friend that suffered some pretty expensive valvetrain damage to his Ram Truck because he was using cheap all Orange Filters, and didn't think the tapping racket his engine made for a full minute everytime he started it up was anything to worry about.

You might want to check your oil pressure as you start the motor, see that it jumps up to the full oil pressure it should for the conditions. And you're not getting the tapping noise just as you start the motor.

My 2015 is ticking non-stop now. When I start it up it ticks, and after warm up still ticks etc. I am going to contact my local dealer and let them look at it. I have the extended factory 100K warranty so hopefully its all covered.

I got a surprise at my last visit to the dealer.....inspection, resulting from loud ticking....revealed broken off studs/bolts holding the manifold/s on. Cost me about $900 but it is still cheaper than buying a new Jeep GC :) I am about to be 80 and the Jeep has 90,000 + on the odometer.

That's my fear, I have a tick for a few seconds when starting cold, then it goes away. It's starting to appear to be an exhaust manifold leak.....

I also vote for the purge solenoid as the first suspect since the engine was not running when you did the CEL scan.
Those things can get loud sometimes especially with sensitive ears.

Keep in mind there are other solenoids (like in the Tcase for example), relays and other electrical devices capable of making clicking sounds.

Might want to try pinpointing the sound with an auto stethoscope before taking it to a shop.
That could save a little of the shop's diagnosing time and a little of your money.

I didn't read all of the above so apologies if I'm repeating. Whenever I hear the engine ticking I check the oil. I've found the HEMI will "eat" oil and be low but no idea under what circumstances. I carry a spare quart or 2 at all times. This has only been an issue a few times.

RDHD23,
Has this issue been resolved for you?

I have a 2013 Grand Cherokee Trailhawk with a HEMI and 80K miles. The exact same issue began for me a few weeks ago. My independent mechanic thinks it is a module that needs to be reprogrammed by Jeep and he cant do that. The Jeep Dealership in my town wants to: replace the transfer case shift motor, replace the transfer case, replace the steering rack and do a front end alignment. That amounts to over $6000.00 of "shotgun mechanics" practices by this dealership! And Jeep charged me a $175.00 to find that out.

The difference in the two evaluations doesn't seem right to me. So, I will be getting a third opinion from a small town Jeep Dealership next week. My Jeep stills runs fine, but this issue, and the fuel pump relay issue that Jeep still hasn't solved, are not making it easy to continue buying Jeeps. I need a reliable vehicle.

I would appreciate hearing if there has been a resolution to this problem.

Thanks,

I am a new owner of Jeep Grand Cherokee 2013 Limited Hemi V8, recently i noticed a noise when its start after overnight. It goes away after 2, 3 mins or when temp goes normal. I am not sure either its from manifold or lifter etc.
Vdo link for more understanding.

Check your water pump sounds like a pulley does it louder when you rev it or does it go away.
Worse Case it's the lifter and your going to need a new CAM and Lifter set. It's a Heads off job.

I never hear any noise while on reverse. This voice mainly comes when its cold start i mean start after over night parking.

I am supspecting either its manifold leak or bolt or as u mentioned lifter but its not constant and after acquiring normal heat/temperature this voice goes away.

Could it be bcz of differnt/bad oil as well??

So u mean if lifter need to cha ge than head will open and than it will be changed?

How much does it cost ideally?

If it's a lifter it's thousands in labor. Parts are close to $1000 Most people replace them with Hellcat Lifters.

Could be a manifold gasket Have it diagnosed or checked. Hemi's have been known to pop the Gasket or bolt on the stud pops off.

Ok so in that case shall all need to be replaced i mean 16 lifters or only the damaged one, what is the recommendation. I showed to a specialist mechanic and he told be with voice mostly its lifter and worst cam shaft also, the price he mentioned are like hell. I am thinking to keep this beast or sale?

I will check with dealer after getting the appointment but confused...

Both heads have to come off so it doesn't make sense to only replace the 1 lifter to only have to replace 1 down the road again. Once lifter fails it typically wipes the Lobe on the cam aswell.

Most People do a Hellcat lifter and new Cam and a MDS delete all same time.

Depending on the Miles Trade that thing while it's warmed up lol make it dealers problem.

I have recorded another video for more clarity and just to pin point the issue, as i mentioned earlier this voice comes only and only on cold start or you can say overnight start after that once the engine acquire optimum temperature its goes away.
Today while i was driving with my windows down, i feel small tick noise while passing on hump, i tried 2, 3 times but that was very very minute. So now i am confused what it could be.
