Traded my '08 SXT in for a '14 R/T on Saturday. 1000 miles on it (it was their demo car). Sounds like the valves are knocking! Even worse when in Sport Mode. Is this the infamous "hemi tick"? Shifts hard with the paddles too.

Please don't tell me I traded one problem in for another!

Put some good oil in it, recommending Pennzoil Ultra or Quantum Blue oil
Also some good brand 91 or 93, but u may want to look into Aces IV
Both of these will reduce that tick significantly but the HEMI sound will be there

Test drive one just like yours and compare for yourself.
If you feel yours is not rite, then move forward with remedying any issue.
A reputable dealer will work with you, if not, document any issues with a Chrysler service garage. It is under warranty afterall.

Well, if you've never heard a modern Hemi before you'll be surprised at the loud tick from under the hood. It's normal for the engine to sound that way.

However, since we can't hear yours it's hard for us to say if it's normal or not.

Since it's a '14 5.7L, I'd say there is probably very little to be concerned about. The newer 5.7L engines have very few issues.

I spent Saturday/Sunday complaining about how quiet it was, then today it starts the knocking. My cousin has owned several 5.7s in various vehicles and he's never had one that made this noise. He's actually concerned that it's a collapsed lifter. I have to go back to the dealership to pick up my add-ons, I'm going to have the service department take a listen while I'm there. Maybe drive one of the other R/Ts in the lot, but mine was quiet as a mouse until today, so not sure if that's a good comparison or not. If nothing else, maybe get some peace of mind.

As far as full synthetic, I was planning on switching anyway. Might just have to do it sooner then I thought.

I truly appreciate the quick responses!

Did u happen to put in some 87 octane or unreliable 89 octane? Crappy fuel/winter fuel will do it louder.
But yes compare it to others.

I filled it with 89 Sunday night. Probably middle-of-the-road quality wise. I'll have to start paying attention to who has the better quality gas around town. May order a few bottles of that Aces IV, since so many people talk so highly about it.

And as an update, it was fairly quiet on the way into work this moring (10mile trip). Definitely quieter than last night, though I did run it for 4 hours straight last night, so it was as warmed up as it gets.

Does it sound like an old sowing machine? Thats pretty much what it should sound like. I've questioned the "hemi-tick" at 2 different dealerships and they both told me it's loud injectors that make the tick sound. They all do it, just some are worse than others. My 5.7L did it and so does my 6.4L. Near identical sounds, and in truth, I don't like it either but accept it.

To ease your mind, I'd take it to the dealership and have them check it out to make sure its nothing more than normal.

I am guessing based on the lack of video its normal....Now add a cam....custom pushrods and headers........The Injectors are crazy loud!!!! Like described above an old sewing machine

Yes, old sewing machine is about accurate. That makes me feel a little better about it. Still going to run it past the service department.

Stevens12, how does that SRT8 handle in the snow? I live about 2 hours southwest of you, and I don't think I could make it through our winters without my AWD. Also, ever have issues running Sheetz gas in it?

Surprisingly, the car did great this winter. I've got a good all season tire and would only assume it would do better if it had a winter set of tires. If you understand how to drive a RWD car in the snow, it's not really that big of an issue. I switched from having AWD to this and quite frankly haven't looked back. I have the ability to work from home if needed and always planned ahead when a snow event was coming, but really never needed to stay home. Obviously the AWD is better, but for the 2-3 days of bad weather, I couldn't justify "having" to keep the AWD. for the other 362 days a year.

Also I'm VERY against using sheetz gas in any of my cars unless absolutely the last resort. They buy the cheapest gas no matter where it comes from and I've seen issues with lawn equipment from using sheetz gas. For that reason alone, I won't go there for gas. You may never have an issue, but I'm not taking the risk. :bigthumb:

I would recommend to have the dealer inspect since you just bought the vehicle and under factory warranty.

Keep us posted after the dealer inspects.

ACES IV and QuantumBlue really stops the Hemi Tick. I have over 10,000 people now running on ACES IV and QuantumBlue with it going away completely by 85% of people and 90% better on the other 15%.

Here is the article I wrote in January of 2010 about it:

http://www.chargerforums.com/forums/showthread.php?t=123111&highlight=hemi+tick

"Many here know what we do to stop the Hemi Tick, but we figured that since there are so many new faces here, they may not have heard that you don't have to have it in your engines.

We have discussed previously that there are 3 culprits that cause the "Hemi Ticking" that is heard in idle and just off idle.

1) Intake and exhaust valves do not have any kind of cushioning from the fuel. Fuel usto have higher amounts of sulfur and tetra ethyl or tetra methyl lead to lubricate and cushion intake and exhaust valves in the old days. When EPA decided to go to unleaded fuels, hardened valves and seats were produced trying to deal with the lack of lubricant. This was adequate at best, but did allow engines to live longer than if they had soft valves and seats. However, when they went to ethyl alcohol, that all changed. Alcohol absorbs moisture and strips lubricity. That was bad enough, but when they reduced the sulfur content from 130 parts per million (ppm) to 30 ppm, it really produced a perfect storm. Both the intake and exhaust valves are now hitting against the valve seats with no cushioning at all. This causes wear, and then of course....noise or TICK.

2) Fuel injectors depend on at least 70 ppm of sulfur to stay alive. When EPA went to the ethyl alcohol and less than 30 ppm, they have no cushioning allowing them to click or tick also while building up gum and varnish. This restricts the flow of fuel and turns the vaporized spray pattern into an atomized spray pattern. Atomized fuel doesn't burn as well, and helps wash down into the cylinders and wipes out the detergents and dispersants much faster. This is the second part of the Hemi Tick.

3) Because the Hemi has a very short skirt and thin rings with virtually no land area, the piston wants to rock in the bores. This is another reason for the moly piston skirt coatings. It is designed to cushion the short skirt. The problem is that as miles rack up, the moly is worn off and a louder engine or tapping noise begins to occur. This is the third part of the Hemi Tick. This part actually contributes to more aluminum in your oil analysis. An oil analysis is always important to do on any engine you want to take care of as a baseline, and then every 3rd oil change, do one just to be sure nothing is leaking or causing problems.

BND Automotive has addressed these issues by:

1) ACES IV Gasoline Formula introduced into your gasoline to replace the lack of lubricity. However, this is not just for the valves, but also for the injectors and the in tank fuel pump. The pump is cooled by the gasoline, but it needs plentiful or copious lubricity as well. ACES IV addresses these three issues to produce a protected, lubricated, and more powerful engine with a great quieting effect stopping 2 parts of the Hemi Tick. This is the injector and the valve ticking.

2) QuantumBlue Custom Blended Lubricants are designed for the different aspects that make up not just the piston slap by adding the right ratios of additives, but also producing much better filmstrength that is necessary to protect the Moly coating that is put on from the factory. This works great not just for the 5.7 and 6.1, but also the 2.7 and 3.5L 4 valve Polyspheric Hemi V6 engines as well. Taking all these into consideration..... cast iron block or aluminum block, cast heads or aluminum heads, carbureted or injected, what RPMs and what mods are added to the car along with what temperatures and conditions the car will encounter matter. Salt from the sea shore is different than what comes from snow removal. Silicates from desert conditions and extra high temperatures need to be addressed as well. Really cold temperatures in Canada and British Columbia also need to be adjusted for. Upper cylinder rocker assemblies are important to consider whether single rocker (SOHC) V6 or double rocker shaft (DOHC) V6. The 5.7 and 6.1 also have duel rocker shafts and are a weak spot for scuffing. Dads SRT even showed on a billet steel cam that the typical Mobil 1 0w40 is NOT protecting the cam. The rollers need to spin on the cam, and not slide. Without proper lubricity, correct filmstrength, and frictional capabilities of the lubricant, engine will damage and wear will occur!

These two in combination will address the Hemi Tick noises which will increase the life of your engine and keep your peace of mind.

Many here have taken advantage of these technologies and are now thinking about other things other than ticking engines since they don't have them any longer.

Brian

You don't have to accept it, you can do something about it Stevens 12!!
