If this is the very first teardown you've found on this channel, here are some of my favorites:
Dodge Ram 8.0L V10 • 8 LITERS OF DESTRUCTION! Dodge Ram V1...
Ford 6.8L 3V V10 • FORD 6.8L 3V V10 TEARDOWN! Big Engine...
Dodge Viper V10 • This Dodge Viper V10 Engine Was MUCH ...
Mercedes AMG V8 • Mercedes M156 6.2L AMG V8 Blown Engin...
Today we dig into a 5.7L Hemi from a 2015 Dodge Ram 2500. This was an engine that was sold at a local auto salvage yard and then returned as defective. Unfortunately I didn't get any details like mileage, or reason for return. These are pretty expensive engines (Around 3500-4000 dollars) which generally means there's a high demand for them. Lets figure out what went wrong with this one.
The 5.7 Hemi had a few iterations throughout the years but this is one of the latest offerings making 383hp and 400ft lbs of torque. Overall I think these engines are fairly reliable but certain operating environments and quickly lead to problems. They do run quite well and aren't particular hard to work on which is nice.
Why am I doing this? I own a full service auto salvage yard in the Saint Louis Missouri area called Importapart. Part of our model includes buying core or bad engines and dismantling them to salvage the good parts from while recycling the rest. We do not rebuild engines, merely supply parts to those who do.
I hope you enjoyed this video, as always, I love all of the comments, feedback and even the criticism.
Catch you on the next one!

😂😂🙈 now i know why you were so sweaty. Not from watching cops

The “Whoever invented the red locking tabs, I hope McDonald’s gets your order wrong” had me lol!

I work on ambulances for my local fire dept., all of the ambulances are 6.4 hemi powered. On average, at 60k miles they wipe a lobe off the cam. Every ambulance has had at least one engine replacement or been rebuilt. These engines despise idle hours because of low idle oil pressure.

I see you dislike the red lock tabs as much as I do. Your preparation for dipstick removal skit was hilarious!

Love your sense of humour Eric.. The combination of mild slapstick, self deprecation and Ironic Sarcasm is just brilliant, and works to a global audience. Wishing you all the success in the world for an excellent channel.

This looks like a classic case of high idle time on a Hemi. If you avoid idling the engine, the lifter issues are mostly non-existent. As someone else rightly pointed out, low oil pressure on the top end at idle is the culprit. There is a "fix" that is preventative. The oil pump from the 6.2L Hemi can be used to generate higher oil pressure as the gear has more teeth to generate more pressure across the RPM range. It is also a direct bolt on swap. Otherwise the best course of action is to avoid idle. Personally, I have this exact engine in my 2015 Ram 1500 Limited. I have not done the oil pump swap, but I only let the engine warm up for no more than 5min before I start driving, and I often shut it off in drive-thrus or anything longer than a stop light. Hope this helps any owners out there!

Cams on these are really hard to pull when they get wiped like this. The cam bearings might not LOOK worn, but if you really check, they're almost always warped. Thankfully the block has enough strength there that it doesn't really matter. Despite everything it's been through, this motor's definitely a very good builder as-is. Probably doesn't even need to go 010. I'd estimate mileage at 150-200k or above. I don't think they drove it much after the lifter failed fully. Also, I'd hang onto that crank. It's very serviceable, and despite being the cast one? 4893356AA is on permanent 6+ week backorder, and I don't know any source for them at all.

This engine is a perfect example of why you don’t just put a cam and lifters in these things when they flatten the cam. It scatters metal everywhere in the engine. Back when these engines were still relatively new and the cam/lifter failures weren’t as well known, the shop I worked at would put cams and lifters in these (and LS’s). They all either had repeat cam/lifter or bearing failures within a year or 2 later. Imagine dumping a couple table spoons of powdered hardened steel into your oil fill tube. That’s basically what happens when the cam and lifters fail.

Saturday engine tear down time after working on cars all day. Thanks for all the great videos.
-
Note the 2019 date on the oil filter - this engine was essentially destroyed and pulled only four years into its life.

There's nothing I like more than having a cup of coffee and watching you doing engine autopsy, however being the old fat and retired and watching you a young man do calisthenics in the middle of it, well I almost choked on my breakfast. That was quite a humorous add-on to this video. Keep up the good work! Your videos are my Sunday morning ritual as my wife and I enjoy breakfast.

Love your dip stick workout, Eric. Thanks for all your efforts to put together humorous & educational vids.
-
Great work sir. Love watching these, I find these tear downs to be super satisfying.
-
Clear proof that training pays off!! Nicely done my friend !! 😂
-
I'm here for the teardowns... And you great style... Enjoy this sooooo much
-
Gold medal for dipstick removal!
-
Good, straightforward approach to any teardown.. and good humor... from a 30yr Master Tech who still learns from everyone

Eric, your weekend engine tear down videos are the best part of You Tube. “I hope McDonald’s gets your order wrong”😄😄😄
-
I have a 2017 5.7 with 290,000 km and I stick to 7500km oil changes and she's been a dream to own!

Eric and Blue your the only channel I can watch 30mins! Keep up the great work!
