Red Line Synthetic Oil 0W-40 - has anyone tried it in the 5.7 HEMI?

[Burla]

oil psi at

2k rpm = 62
3k rpm - 70

that is 5w30 in a 5.7.

 

[Burla]

Academic question, what is danger of too high oil pressure while driving? Gasket leaks, mechanical damage over time? Just curious, best I can relate it to is high blood pressure in people lol.

It depends on WHAT is causing the psi increase, often something causing it can be the problem need fixing. Whatever the issue can be it can also cause the oil pump to work harder, but yeah main risk is likely leaks. The question is what psi would we worry? I don't really have the answer to that one.

When your oil is not at least 212F (or close), the additives in it haven't fully activated, so no, it's not a good idea to drive it. Of course, you can drive it slowly, but not put the hammer down.

WOW! Is that with the engine fully warmed up and the oil at 212F or above?

@Burla I took this video yesterday, 70 miles after putting in 15 oz. of Lubegard Bio-Tech. Can you please tell me what that hot idle ticking noise is? I always had it. Is the fuel injectors? I bought a stethoscope and the only thing I can hear when listening to the valve covers is like something is rolling constantly, which is probably the lifter rollers. It sounds the same on both sides of the engine. That noise drives me nuts. I can also hear it while driving, though it's not loud, it gets a bit louder when I slightly press the throttle, like going up a grade on the highway, so the RPMs don't really change. I guess it's the injectors, but I'd like to get a few opinions. Thank you.

The formula in redline can only do so much, basically luck and testing showed it helps a lot with lifter tick. I don't think what you are describing is cold piston slap, by any chance can you get a video capture of the noise and post it? I wouldn't worry about your psi numbers, they are in normalish range.

Thanks, I'll try and capture video of it next time.

That high pitched/screaching tick? Yeah that bugs the crap out of me too, these hemi's make so many different noises and ticks, they have got to be the noisest engine in existence. My understanding is that this particular "tick" is not lifter tick, but injectors and is "fine". Yet I'm quite sure not every hemi 5.7 makes that noise, I've heard one go buy that was absolutely dead quiet and all you heard was exhaust, like a 90's v8 sounds.

 

[Burla]

Those were cold psi.

You don't have hemi tick from that video. I always tell people when you do a video capture it needs to be under the engine. Somewhere around the 13 second mark I hear a lifter, but it is like a 1 on the 1-10 scale, the engine sounds really good. You can always do a uoa to back it up.

I think a large problem is we (me included) talk about hemi tick and cam issues so much it messes with people who don't have hemi tick. You can drive yourself crazy chasing sounds, but if you are really worried a uoa will tell you how the internals are wearing or not wearing.

Yep, totally just noisy injectors. That motor sounds fantastic, honestly.

Here's my warm idle psi, ~700 rpm.

 

[BadHemi2014]

I also agree with Burla there is so much about hemi tick on this forum, because there is a dedicated bunch of folks who have experienced it and are working to find ways to fix/ improve it, that it can make y'all paranoid lol

Here is MY hemi tick just for reference, sorry to those who have seen this before.
Keep in mind I have multiple broken exhaust manifold bolts so that is all or most of the noise. But i also saw metal in my catch can recently...

 

[Burla]

Thanks for posting that, lifter tick also sounds very similar to that. If your truck don't sound similar to that, you don't have hemi tick.

 

[ramffml]

This is what my truck sounded like before Redline. The truck starts, and then about 1 second after starting it really gets loud and "in your ear" with a metallic chirping/ticking. I believe that has been reduced a fair amount, I'll do another recording shortly. But I have no idea what that sound is.

(Link above, have to make sure you click the little "volume" icon to turn on sound, the video has sound but you need to turn it on in the video player)

That isn't hemi tick at all. If you are lucky a pulley bearing. But if redline made that quieter, I don't know what it can be. Has dealer seen that?

Those are the loudest injectors on a port injected I've ever heard in my life

First of all, don't worry about the metal in your oil catch can. More than likely it's from the catch can itself. Install one of these: https://www.amazon.com/gp/product/B07SMPN7B3/ref=ox_sc_act_title_2?smid=A30A036E461J8Q&psc=1

They actually work. Use the included aluminum washer with the flat side towards the plug and the rounded side towards the oil pan. Hold it with three fingers towards the magnet end when you install it, otherwise, it will fight you want to stick to the outside of the pan. That magnet is very powerful. I can't wait to change the oil on the HEMI to see how much good is stuck to it. I will post pictures for sure.

What kind of oil are you using?

Can you recommend a decent catch can? That's the next thing I'm installing on my truck.

Thanks for posting that, lifter tick also sounds very similar to that. If your truck don't sound similar to that, you don't have hemi tick.

Yes, pretty much. Still, in my case, I was worried it might be something else wrong with the engine. I guess my luck with this truck is that I always babied it. I can't believe that for almost 4 years I fed it 5W-20 just to be "by the book". That's one of the worse viscosities you can feed a HEMI. Well, maybe if you feed it RL 5W-20, but why would you? It was designed for 10W-30 ~ 5W-30. These days there is almost no reason to run 10W-30 unless you got a DI motor and are a cheapskate and want the cheapest motor oil with low NOACK. But I digress...


@Burla I got some thoughts on Red Line, Moly, ZDDP, and Lubegard, and I think I know why some things work and some don't. Just please answer me this one question: if I install a filter the size of the SRT filter or the Royal Purple 20-820 (I will install Purolator BOSS PBL24651), can I put in 8 quarts of oil safely, or do I need to stay at 7.5 quarts? If you can answer this for me then I can run some numbers and post the results here. There might be a better way to protect these engines than just buying Red Line all day, especially for folks who can't easily get it. Okay, I'm always budget conscious and I like to save money, so that's also a fact. I will run a Blackstone on my current fill as soon as I drain it, as I'm curious how Lubegard changed the Mobil 1 FS 0W-40 and post it. Anyway, back to 8 quarts: the reason why I'm asking is that with 8 quarts it might be possible to use an entire quart of Lubegard without thinning out the oil too much.

 

[Burla]

Disclaimer, I wont be saying what is right and wrong on fluid capacity, for informational purposes only I use 8 quarts. Not really out of any strategy, but the dip stick has been off a quart in mine since day one. Never had an issue with 8 in my truck.

 

[Dodge 1500 4X4]

This discussion is timely! I'm running 5w-30 redline with the RP oil filter (there are 2, but the smaller one, forget part #). I've noticed my truck might have some piston slap? Only at cold starts and then only after I drive for about 20 seconds and then stop and idle again after that.

So I start truck, wait for revs to settle, drive off and hit about 50 km/h then pull into a driveway and park/idle. At that point I hear a new noise which might be piston slap, doesn't sound the same as the ticking I had before and is not constant. Just once every few seconds I hear that noise.

But if I do longer trips I never hear it.

However, I have noticed my PSI's during that first 20-30 seconds of driving after cold start, will sometimes reach as high as 4.2 bar which is almost 61 psi. Is that normal? Quite soon after that it drops down to 3.6 bar = 52 psi.

Was waiting to comment on this, My truck on a cold start, I get a rattle in the bottom end sounds like dry start rod knock to me and i can hear it real well from the inside of the truck, not as bad in warmer weather, my theory on this is Rod #7&8 get oil last because of the front sump oil pump being located in the front of the engine, other engines have it located in the rear of the pan, also it could be the good old short skirt piston slap, I talked to a man that rebuilds 5.7 Hemi's that says these problems exist and when he's torn down the engine there was little or no wear on the Main and rod bearings, on #7&8 but did show wear for piston Scuffing in the cylinder bore, but not significant.


To sumize this refrain from idling the engine for a large amount of time make sure you have a Royal Purple oil filter W/ silicone drain back valve and synthetic media, I have a SRT filter on mine, am disappointed about the paper media back to royal purple 20-820

I have about 2700 miles on my first run of Redline 5W30 with RP 20-820 filter.
I splurged on the Billet Tech catch can, but have read good reviews of the UPR catch can as well as some Amazon cheapies. There's a few threads around here discussing them.

Can you cut open the srt filter? I think there are some youtubes on srt filter and it being spun microglass.

@Burla, here are two more short videos. This is "current", done 1 hour ago after running Redline 5w-30 for 4000 km.

First video is "cold start". Two noises, one is a deafening "tick" though not what most people consider the "hemi tick". Second noise is more of "knock knock", little harder to hear, but definitely noticable near the end of the video when I move under the engine (again, have to click the volume icon in video to turn on sound)
https://imgur.com/BR9DBqY

This second video is after engine is hot, 20 minutes driving around. The deafening tick is still there (whatever it is), but the "knock" seems to be either gone or noticeably reduced .
https://imgur.com/a/FrurInI

Any idea as to what those sounds are?

(I also take back my original thought that Redline reduced my noise, after listening to the video again through headphones, it's still there, no difference between couple months ago and now after switching to Redline; but again, I don't think my particular tick is the "hemi tick" after all, after listening to my engine recording vs recordings of the actual hemi tick on youtube and posted in this thread on page 5).

 

[Livinalittle]

I'd use 0W40 if I lived in Alaska....but for North Carolina, I'd say you're better off with 5W30.

That most certainly isnt lifter tick.

I can't say for sure, I am hoping for you it is exhaust manifold related, which is possible as it has the same cadence as the stroke of the engine. I just never heard it like that. Maybe for some reason there is something different down there with your then average bolts. Have you looked under truck at bolts?
