What is this sound?

[AustinH]

Hey guys, I have a 2017 Ram 1500 5.7 and I am trying to figure out what this noise is. Seems to be the loudest while cold and definitely louder while in drive or reverse. Almost goes away when on park or neutral. Doesn't completely go away at operating temperature. I had a shop have a listen 6 months ago and he told me it was piston slap and nothing to worry about. Doesn't really sound like the lifter issue or an exhaust leak to me, but I'm no expert. Sounds to me like it is coming from the flex plate area. Any help would be appreciated. See link below

Definitely not an expert but check your manifold bolts for good measure. That'll tell you for sure. My hemi just had the bolts replaced and it still makes a quick ticking noise

Could be piston slap or lifters. Check the exhaust manifolds for loose heat shields or broken bolts. It probably not that since it doesn't clear up when warm.
How many miles / KM on your truck?
What oil do you use?

 

[AustinH]

Just removed heat shields and checked all bolts. All are good. I have 136k miles on the truck and use 5w 20 full synthetic. I also tried that Lucas oil additive, almost seems to have made it a bit louder. When I'm under the truck with it running seems like it comes from the flex plate area. Doesn't really sound like the lifter noise to me but I could be wrong.

What brand of oil? Our hemi's like Moly (Molybdenum) which some oils lack sufficient amount of. Pennzoil, Quakerstate, Redline are a few popular brands with moly.
Here's a thread that addresses oil issues.

Synthetic Oil

Control system, royal purple, or valvoline synpower? Which would you or do you use? Also is the oil change message triggered by a specific mileage engine hour or what? Sent from my LT26w using Tapatalk 2

Many users have had good results using Lube/Gard Bio Tech Engine Protectant.

Did Lubegard Biotech kill your hemi tick??

So we have had a couple guys running biotech so we should start seeing some results, and hopefully this thread will encourage people with hemi tick to try other lubrication strategies. For those that follow, Lubegard Biotech is similar science to Redline, and as we have seen it can be an...

There's also a great YouTube vid demo of a before and after using Lube/Gard.

Redline 5w30 has helped many on this site with noise. Try it. It makes my engine almost unnoticeable, except for the injectors . Costs more , but worth every cent in my opinion.

Heck to the YES!!!

I switched to Red Line 5W30 High Performance Oil and a Royal Purple 20-820 oil filter and my HEMI is the quietest and happiest its ever been... and I'm now at 136,000Km's (purchased new in 19').

It sounds like a little bit of piston slap switch to 5w30 synthetic also that lucas **** is No good its used for engines about to blow up to make em last a little longer thats all its good for. Also how often do you change your oil? are you orig owner or got it used?

I purchased brand new at the end of June 19' with call it 10km's on my truck... FFWD to today at 4+ years of ownership and I'm sitting at 136,000Km's on my truck and I just recently switched to RL HP 5W30 oil and RP 20-820 oil filter under 20,000Km's ago (I always previously used synthetic 5W20 oil and either a MOPAR or DELCO oil filter and changed at 6,000Km intervals).

Huge improvement in how my HEMI sounds and operates with this new oil and filter combo. Is it more expensive, yes! Is it worth every penny to me, yes!

I now go 5000 miles (8,000Km's) between oil/filter changes and that's a perfect time to ensure my investment keeps me and my family dependably on the road.

I plan on 500,000Km's of ownership experience with my 19', and through the brain-trust in this forum I fully believe I will now achieve this.

I use 91 fuel and this oil and filter combo and drive my HEMI like it's supposed to be driven. I am hyper diligent on my predictive and preventative maintenance, and because this truck is my lifeblood to my career success, it is worth going this route to ensure I am successful, and more so that my daughter and me are safe in this truck every single day we are in it

Thanks for all the responses guys. I am the 2nd owner, I have owned it since February of this year. When I bought the truck it had slightly higher idle hours than drive hours which is crazy to me and obviously horrible for your engine. I've only done 1 oil change so far using penzoil 5w 20 high mileage full synthetic. I will definitely try the Red Line 5w 30 high performance oil and RP filter though. Also I disconnected my injectors one at a time today to see if I could pinpoint a cylinder. The noise definitely got quieter when I disconnected cylinder 5. Now I'm excited to do an oil change even the I have 80% life left. Lol.

You can get Redline oil and Royal Purple filters at Mopac on 16th ave in Calgary,JB's also carries it,but sometimes their selection of Royal Purple filters leaves a bit to be desired

 

[AustinH]

Thanks, I was just looking up where to purchase. The filter for my 2017 shows a different part number than the one you mention though?

Don't be set on what the EVIC says regarding idle and drive hours.
Mine has changed several times since I purchased new in 19'
This is a known issue with our trucks in that this logger is quite inaccurate.

Recommend you go with 5W30 Red Line High Performance synthetic oil and the Royal Purple 20-820 oil filter and change every 5000 miles (8,000Km's).

Perhaps request an oil sample collection kit from Blackstone and send in for a Used Oil Sample analysis & post up, too. This will net you inside observation on the internal health of your HEMI

EDIT - the Royal Purple 20-820 oil filter is a tad larger and still fits the stock 5.7 HEMI application

Where in Ontario are you obtaining the RP filters?

Ordered a dozen from Summit. No place to find them here, unfortunately.

My truck is making the exact noise (82k). It’s getting traded in next week on a Cummins, I love the ram lineup but the hemi issues are not worth it.

Did you ever figure out the cause of the noise?

 

[Tominator223]

Check torque converter bolts to flex plate. I’ve seen them loose before. In many different vehicles. V6 mustangs had issues were they would get loose & cause noise , vibration. Some 80’s gm’s as well. It maybe be lifters or exhaust. As they have issues
