Beginning of HEMI tick or piston slap?

Link to the noise on YouTube. May need headphones to hear it.

It now makes a knocking noise but it’s not consistent. Seems to happen when truck is cold

I have some noise cancelling headphones, I can hear something but that video isnt close to be enough to gather anything. Try leaving recorder under wheel well for 2 full minutes so I/we can hear a better sample.

I caught one of the main concerning noises much louder. This is after driving all day with a bit more idling than usual with some medium duty towing. This was 2 starts after I disconnected my trailer when I was about to head home.

My phone stopped recording halfway through but there was another 30 or so seconds of that video

Sounds like a normal cold startup on my 5.7 when I fire her up on a cold morning most the time it will do this its the MDS lifters deflating overnight takes a second for them to fill up. Use a good synthetic oil/filter and some lubeguard def helps.

This unfortunately is a warm start. I had shutoff the truck maybe an hour before this. I will definitely be using a better oil and filter than what’s on it on the next oil change. Redline is hard to get where I am so I will have to see what’s close.

Use penzoil 5w30 syn thats what i use in all my hemi engines appear to run quieter it and if those where hot starts wow I mean it has happened to me on hot starts but not that common at all.

It isnt that bad, to be honest that is the type pf thing redline just erases, I'd try 0w30 for your location if it is redline. If you decide to get it, I have some ideas on filtration and extending interval that can make the extra effort worth it to some people. Yes lubegard might work as well, but it is less effective then the voodoo we call redline. Alternatively, I'd try a 0w40 which do not threat technically speaking they are 5w30 most of the time, I imagine it would be also hard to get royal purple filters, if you can find a 20-500 and see if it fits, and get a fram xg2 as a backup. Look up BITOG forums for high moly 0w40's, I know some guys I trust said 0w40 amsoil is a tick killer two trucks. PUP 0w40 as well, and if you want something else look at bitog for those high moly voa's, over 200ppm. You need to consider additives, viscosity, AND filtration, they are all important if you want to kill a tick. If you use the 2016 recommended filter size,. it might be as simple as switching to the larger filter, yes it can be that important.

Thank you Burla! I appreciate your input. This is very helpful. If I can get my hands on redline I’ll grab some. I’ll look up BITOG forums and see what’s there.

Would an Hp-107 work from K&N? That seems to be the most readily available filter that’s around me. I see it not mentioned all that much. Is there an issue with it?
