: Clicking sound in 5.7 Mopar 10?

Help? My new Mopar 10 Hemi makes a ticking sound like a clock, very audible at idle. I pulled up to the bank and McDonalds drive thru and could hear a distinct regular ticking sound. Like a fast clock. Is something wrong?
It's not an engine 'knock', just a ticking sound.
Please help if you know of this or if this is normal. Thanks in advance..

I think they lovingly refer to this as the "Hemi tick".

My new Challenger has it a little... but its more noticeable in the wife's 300c

To me it sounds very similar to my 74 Challenger, which has a set of Rhodes Lifters in it.
Rhodes lifters = the original Variable Timing lifter.
So I haven't worried about it too much...

But I'm sure some of the mechanic's on here will chime in with the a more detailed explanation.

My R/T had a similar noise when it was new. After I changed to synthetic and put 3500+ miles on her, it's now around the Hemi noise parameters. One thing for sure, your not going to take it in to the dealership and let them tear your motor apart for this! Give it time, you still have plenty of warranty time and if by chance it does go bad, then they would have to fix it right.

Be careful about some technicians at Chyrsler. One told me I didn't let the motor break in because I used synthetic at 1200 miles.

Thanks for the tips. I'll monitor the situation, change to Mobile 1 at 3000 miles and see how he is.

Roller lifters in it. And wait until about 6K to go to synthetic. Let the rings seat first.

My 'tick' is definitely coming from the engine, not the exhaust. I pulled out an old trick from way back which some of you will know.
Cut a broom stick off, place one end on your ear and the other on various parts of the engine (when it running but not near moving parts). I could hear mine in the valve train (heads). I don't have a clue what causes this but with as many of you that have heard it, it must be common. I've got 1200 miles on mine and I think it's quitter but I'll see. I'll check when I go to the bank drive thru or McDonalds this week. Meanwhile, I'll save my old broom stick and get a vacuum cleaner for the kitchen...:)

Mine is at the dealer now to have bubbles in the grille surround and under hood panel fixed. Grille surround is being replaced. I think they are repainting the under hood piece.

Anyway, since the warranty is running out this year (2nd owner on 2009 gave me balance of 3 years) I asked them about the tick. Mine used to do it all the time, which was embarrassing at times. Starting in December - colder weather? though it seems counter-intuitive - it now only does it when the car is cold. It's quite loud and gets louder at lower RPMs. If, after a cold start, you wait for the engine to slow down, then put the car into gear, hold the brake and slip the clutch to slow it further, you can really hear it. It disappears at higher RPMs. Or maybe you just can't detect it then.

The folks at the dealer took days to investigate. I'm very lucky to have a dealer I trust. I've worked with the same service manager for years and their mechanics seem quite capable. They said that after further investigation and talking with Chrysler, they'd recommend not tearing down the engine to check for the source. They said they could not find anyone who knows what causes it or how common it is. They want to check other cars like mine - 5.7 6-speed - and see if they do it too. If not, they will go exploring if I want them to to try to find the cause while I still have warranty left.
I expect to be trading for a 392, so probably will ignore it unless there's some magical fix in the LX forum.

Suggestions or other info appreciated.

Heck, I used to be one of the guys playing on stage - that is loud!

But the ticking is barely audible standing beside the car at idle but when I pull up next to a building, such as a drive thru, It seems pretty loud. I only have 1200 miles on mine so I'll watch (or listen) it closely.

I am so glad to read this thread. I have been telling hubby for months that i hear this ticking noise, to which he thinks Im crazy. I hear it mostly when I start the car up in the garage, in a parking garage, a small semi-enclosed area... and at lower rpms.

Are you guys sure you're not hearing the fuel injectors firing? They are quite prevalent on the hemi.

It's not the fuel injectors. I hear those too, once the engine warms up and the "Hemi-tick" is quieter or goes away entirely.

This past summer, the tick was continuous, warm or cold. Now it's only after the cars been sitting over-night until it warms up, for which I am thankful. The dealer heard it and investigated for several days. No idea what's causing it. Says Chrysler thinks it's normal and not worth pursuing. If you Google "Hemi tick cause" you'll find lots of other ideas. The only one that seems to work for the largest number of folks seems to be to change to the 6.1 exhaust pushrods, if you have the 5.7 engine, and longer aftermarket exhaust pushrods for the 6.1. Looks like that gives you about an 80% chance of success, though some that said this was an initial fix also said the tick returned later but was not as loud.

This seems to have some validity to me because with my Blastin' Bob's setup, I can actually hear the tick in the left side exhaust tip. The dealer did as well.

Elusive! and apparently has been for decades!

Now... I'm wondering, if I get the 392, is it going to also have the genetics to inherit the tick? We'll see.

I USE to get the tick when I first started it until the oil pressure come up and fills the lifters. I wouldn't even worry about it. I don't hear it now that that it has a few more miles on it.

deezlman
02-05-2011, 07:52 AM
I used to not hear it at all. Started at around 14k miles making the sound any time the engine was idling, but now, at almost 18k is not as bad and no longer occurs after the car warms up. Different oil maybe? I used to use Castrol's synthetic blend and, in an effort to "cure" the tick switched back to their non-synthetic (what do you call regular oil, organic?") just to see if there was a difference.

I've heard valve train noise due to lifters that have leaked down and maybe the ones in these cars sound different, but it doesn't sound at all like lifters to me. And, I can hear it at the end of the left exhaust pipe. I don't think lifter noise would travel that far.

I tried to record it on my iPhone, but too much background noise and you could just barely hear it if you knew what to listen for. I might try to rig a better recorder somehow, capture it, and post here to see if we're all talking about the same noise. Folks with normal cold lifter noise think that's what we're talking about, and I don't think it is.

MoparTen
02-05-2011, 05:15 PM
Well, I've got 1200 miles on it and standing outside the car at idle, I can only hear it if I listen for it. Barely audible. The best place to hear it is at McDonalds drive thru next to the building. It's not as loud now so I'm gonna chalk it up as a Hemi Sound. Hemi is why I bought the car so I'd better start to like the 'tick' even though it is diminishing.
Thanks for all the comments - I'm glad I'm not crazy (well, I am, but I am hearing things too... )

My 05 300C made alot of Lifter/Pushrod noise for the first 5 thousand or so. Now shes real quiet... for a Hemi . Also the fuel injectors make a ticking noise so don't count that out. Be cool and drive the car for a while. It'll quiet down.:thumbsup:

The tick is quite common. My 03 Ram ticks all the time and my 06 300 and 09 Challenger tick sometimes. My wife's Aspen, with cylinder deactivation, does not tick.

Over the years, I've heard several good explanations...but nothing definite. Don't worry about it.

....many folks eat fast food on ocassion or at least one point in their life. Get over it or join a nutrition/health forum where they might care.

As someone mentioned earlier, I can't help but think folks are talking about different noises. The tick I have been hearing sounds very much like an exhaust leak coming from under the car around the transmission area. If you stick your head in the engine compartment, you don't really notice it. ....only outside of the car and/or as the noise reverberates against walls and such.

Park your car, walk around McDonald's 5 times, go in and get their new oatmeal and a cup of coffee :guiness: (Dr. Oz said coffee may help prevent cancer - he really did!). Oh, wait. There's no way I'm parking my Challenger in any McDonald's lot around here. Nevermind...

Still ticks. Going to try to get a decent recording of it. Have tried before, but too much background noise using my iPhone. Will try something different.

Anyone else tried to do this? Maybe we could compare sounds.

Ok, I think old memories came to me. Back in the days of the muscle car Hemis, some people didn't want them because they said one had to always keep the lifters adjusted. They were called 'Solid' lifters and they definitely made a 'ticking' sound like mine does (although it is better).

Question> Do todays Hemis have 'Solid' lifters? If so, I know where the ticking is coming from.
I'm pretty old and even the very first Hemis in the 50's. I hope someone can answer this one.

No. The lifters are hydraulic. Though, I think they're much improved over the old hydro lifters to allow higher RPMs without getting "squishy."
My old "ironhead" Sportster (bought new in '76) has solid lifters and even with the rather loud exhaust, you can hear them, especially if the gap gets too wide. Also, my 98.5 Cummins 2500 has them. They've been adjusted once at 150k miles, per the manual. Paid the dealer to do it (24 valves = 24 lifters?). I don't think I can hear them, but you can't hear much of anything with the hood up and the diesel running - love it! LOL

If it should start again, I'll start a new thread and hopefully won't venture into our eating habits.

Doesn't seem to be a problem at all, just normal engine noise. My exhausts (soon to be changed) are super quite so I can hear the engine real good and I think its ok. Now that I've said it, watch it start again.....

Just came across this thread. Mine had the tick for 2500 miles. Did an oil brand switch and it went away. Now I have my oil custom made winter weight 7.5w x 23w and 12.5x35 summer at track oil.
Something to think about, when you hear the loud ticking so does you knock sensors, its then called false knock, the sensors dont know that and pull timing reducing HP and milage. My exhaust mufflers used to hit causing the knk sensors to pull timing also.
Yep the tick might not hurt nothing but milage and HP, I still dont think any should be ticking. My wifes new camery ticks and its going back.

Do you recall what you switched to when the tick originally disappeared?

It's odd to me that just after an oil change (not necessarily changing brands - just fresh oil/filter) I don't hear the tick for a while. Then, it's back.

have the same little tick. There is no worry for you unless you hear KNOCK
KNOCK KNOCK. I did the same thing, listen to the tick and think the lifters are ticking. These engines are tough. Remember TIMEX watch ?

After all the posts and personal experience, the Hemi's have a louder ticking sound when they are new. At about 1500 miles, you have to listen for it to hear it. Just a chapter in the birth and life of a Hemi. Thread dead I think.

I'm not entirely sure about that...my 6.1l still makes the ticking noise until I actually start driving it around and it REALLY warms up (remote start it'll still have a few lifter ticks) and my engine has about 10-11k on it, I highly doubt there is anything wrong with my engine, so I guess it's just the nature of these suckers to tick tick away.

02-25-2011, 10:57 AM
What you are hearing is coming from the lifters. It is caused by having too much or too little preload on the lifters. My 318 in my 1994 Dakota did the same thing though not quite this loud until I installed adjustable pushrods in the engine. Didn't want to spring for a set of adjustable rocker arms. After the install, the ticking sound went completely away. Does the Hemi have adjustable rockers or non-adjustable rockers? Stamped or roller rockers? More than likely non-adjustable in which case I would guess that the lifters have to much preoad on them. You normally want only an 1/8 to an 1/4 of a turn of preload on the lifters. Sometimes having only that much preload can cause the valvetrain to chatter. You just give it a little more preload at a time until it quietens up. It will make the most power with only a 1/8 to an 1/4 turn of preload, but it might be noisy. If it has too much preload, it can be worth up to 20 foot pounds of torque if you adjust it out by using adjustable pushrods or whatever.
The only way to know which it is the next time someone has their intake off is to check the preload on the lifter. Or by calling Arrington or Speedlogix. One of them should know what the deal is with the preload.

Sdave
02-25-2011, 11:01 AM
I would like to believe that the engineers put the correct length pushrods in the engine to give the right amount of preload once the roller lifters wear in. But I don't know that.

Mine does it from idle to about 3000rpm hot or cold and seems to go with the speed of the engine. Oddly when in 5th or 6th gear i can barely hear it. I hope it is nothing and goes away...It sure is anoying though.

Pythonman

Mine started doing this when it was new, it wasnt very loud. Then it went away at 1000 miles when I did my first oil change with Mobil 1. Every so often I'll just barely hear the tick ticking but it's not consistent. And as others have observed, when I have a fresh oil change I don't hear it at all. Not worried about it in the least. Personally I think the engine just gets a nervous tick when it hears my right foot coming near!

My clicking situation is really weird. Cold start up never, but if you were to shut the motor off Before it gets warmed up....the next time you start it back up I sometimes get 2 seconds of noise. I learned to beat this if it's still cold and not all the way warmed up, I first rev and hold at 2000 rpms for a few seconds and then shut her off. Always works, no noise when you start it up. I think with doing that the oil pressure charges the lifters with more oil so there is no gap in the lifters.

The ticking is normal in the new Hemis, I hear it on every new Hemi powered vehicle that I do the PDI on. Some seem to be a little louder than others, but none have been excessively loud. I like it, it makes me think of the old 426 Hemi cars that I drove and worked on back in the day.

Mine went away today after 1600 miles on the car! Not sure if the weather has anything to do with it, its 90 outside in michigan today. on the drive home i was keeping the RPMs high and also was taking it slowly up to 5500 rpms and back down. Don't know if that had anything to do with it. So happy that stupid tick is gone. Now they only need to fix my nav, seat, upper console, door panel, sunroof and weather stripping....
