The camshaft on a gen 3 hemi does not receive oil solely from crankshaft splash. I have several videos showing the oil pathways through the engine that clarify this 👍

I don't see any reason to do so no. The Hellcat vehicles use the same overall volume of oil in those engines, so it's not like you need any extra capacity. It might help oil temperatures, but I don't see much benefit past that. 👍

Also it's a high volume pump, not high pressure. I discuss the difference in that video I linked as well. 👍

Primarily just an annoyance, but prolonged it can eventually cause your oxygen sensor to read lean on that side, meaning you will be running rich on that back and it can affect your gas mileage.

@@ReignitedAuto thank you for the reply!

If you put the stock pressure relief spring in the new pump no changes will need to be made to the software. 👍

It's not specifically showing this pump, but during this video I show how to replace the pump on a Magnum, which is the exact same process on a charger challenger or 300. kzbin.info/www/bejne/raHPaZSQnrV-Zqc

@@ReignitedAuto thanks a lot. I’d be looking to do it on a 2018 Grand Cherokee.

@barefootrocker is definitely a bigger job on one of those, you'll have to drop the oil pan to install it.

I get this sentiment a lot from people, but I don't believe it to be true. Rather, I feel like it's a combination of negligence, stupidity and indifference that leads to these types of issues. Is it better or worse if it's intentional or just stupidity? 😄 What I have found throughout my years in the industry is that engineers will tend to design something that works pretty well, then the accountants get involved trying to get them to make something that's cheaper if a bit less reliable. This scenario usually seems to be the source of failed components.

What exactly did you install?

I did the cam and lifters and all new gaskets. Cleaned the hell out of it, new plugs and sultan of spark coil packs

@papigrande42380 OK well I have some good news for you, this is very common and if I'm correct the fix is pretty simple. Watch this video here: kzbin.info/www/bejne/oH7dmoCnjLeAoZI If this doesn't fix it I would be surprised. 👍

I've heard this from a couple people over the years, but I've never seen a non Hellcat pump gear that is 16mm thick. Would you be willing to send me photos of the pump and your measurement to [email protected] I'd love to see it. 👍

Thanks for watching i appreciate it!

Harmonics. Frequencies change based on a bunch of different factors. Think about if you have a dash rattle that goes away when you go slower or faster, or if you change gears. When the engine goes into MDS it drastically changes the vibrations inside the engine and can in fact mask noises.

Yep, that would accomplish the same thing and I have heard of fleet companies doing this very thing. 👍

That's correct but if you don't swap out the lifters to non MDS ones you'll constantly be in 4 cylinder mode since it's oil pressure in those bores that collapses them.

I'm not sure you're going to be able to get this part from a parts store. It might be a dealer only part since it's bolted directly to the valve body. The part itself is called the solenoid pack. The temp sensor is integral to this part, it's what the electrical connector on your transmission plugs into. I don't have any access to part numbers right now since I'm still off work due to injury.

​@@ReignitedAuto Thanks for the input.😄

That's the engine oil temp sensor, the trans temp sensor is in the solenoid pack on top of the valve body. Replace that and you should be good to go. May as well replace the trans filters while you're in there.

This is actually a fairly common issue with these older vehicles. You mentioned you replaced the sensor. The trans temp sensor is internal to the solenoid pack on top of the valve body is that what you replaced? If not, that's what you need to replace next. 👍

On cold start I would be much more focused on exhaust bolts broken rather than a lifter issue.

@@ReignitedAuto thank you so much for the response I just checked and sure enough it's the top rear bolt popped flush with the underside of the heat shield so it looks like an easy fix thank you thank you thank you, you just earned a sub for as long as i own something with a hemi, you're my go to!

@@John_Doe-007 right on, good to hear it! 👍

Did you even watch the video? 😄

Technically yes, but not without serious changes. The intake manifold won't fit, the accessories would have to be changed, and most importantly the crank trigger would have to be swapped from your original crankshaft to the new one so you'd have to completely disassemble both engines. There's a few other minor things that would have to be changed but those are the big items. It can be done, I've got a 2017 392 in my 05 magnum, but it's not a simple swap.
