JUNK Jeep/Dodge 3.7L V6 Engine Teardown. Is This Why These All Fail? (OIL CHANGES MATTER)

Today we tear into a VERY Destroyed 3.7L Powertech V6 from an early 2000's Dodge Ram 1500. This engine is claimed to have 146K miles which normally isn't what I'd consider high mileage. It certainly can be for the 3.7L, which suffers several different types of failures from dropped valve seats, broken pistons, blown head gaskets, and oil consumption. This one actually lasted quite a bit considering the horrible condition inside. Its clear why this particular engine blew up, and its not the engines fault!
Every week I teardown at least one blown up, bad, or core engine. Check out some of my favorites:

[@jamiechampion299]

I own one of these in a 2004 Jeep Liberty. So far it's at 140K with zero major issues. It likes to burn through oil, so I never have a chance to forget to change the oil. It's not amazing when it comes to efficiency, but it's an old Jeep, so I'm not surprised. For what it is this is a surprisingly decent engine. Sure, it isn't very powerful (210 HP, 235 lb-ft), but that's fine for me. In a vehicle the size of the KJ Liberty I don't see the need for much more power. At one point my coolant reservoir decided to dump coolant onto one of the spark plugs. The engine was still running despite one cylinder being full of coolant. Changed the plugs, fixed the coolant leak (broken inlet on the plastic reservoir), and it's been running perfectly ever since. As long as these engines aren't overheated they tend to last a good long while.

Yeah that oil burning is going to become a bigger problem for everyone in a ICE vehicle as time goes on. they are using thinner rings to reduce friction to get better mileage out of the cars. Those rings start letting oil slip at around 100k miles. It's considered "normal" by the manufacturers. I miss good ol cast rings.

I pulled over immediately when I saw the fluid coming up on the windshield, replaced the hose and 4 gallons of antifreeze later, I fired it up and it bellowed white smoke from the exhaust.

It wouldn't have been worth it; though, had I not done all of the repairs myself...

[@crisnystrom]

12 years ago, my Mrs. bought a Jeep Liberty with this engine; 150k miles, 4WD - 45RFE trans. She paid $500 (five hundred) as her better friend wanted it gone. Needed full tune up, valve cover gaskets and a radiator. I use cheap 100% synthetic and an even cheaper filter. 238K miles, still strong runner and after 6k miles, maybe a 1/2 quart low on a change. The only major work needed was at 156K miles when my teenage daughter felt it OK to ignore the claxons, CEL, and temp gauge in the red-red after the water pump DOAed. She drove it about 15 miles all the way home with a most terrific clatter, steam and smoke pouring out. Replaced right side head, new timing kit, gaskets, and I found a "good used" pump that a local scrap dealer had in a large cardboard box full of "good used" pumps! Else, original engine, original trans....nothing but fluid changes and rubber parts. Even has cold AC!

[@billgraff4809]

Eric, watching your videos is a great, entertaining way to learn which engines to avoid and why. It's a true shame that so many vehicle owners flat out ignore basic maintenance and also never check their oil! After owning many GM vehicles from the 1980's to mid 2000's- none of which ever used more than a quart of oil in 3,000 miles, buying a new 2009 Subaru Forester with the EJ 2.5 was an eye opener. First quart used in 2,000 miles. Second quart in 1500 miles later and nearly a quart low at oil change time, 5,000 miles. It was consistent with this pattern through 73,000 miles when I traded it in. I hope the person who bought it checked the oil....

Only maintenance have been 2 radiators on each and the a couple water pumps. Liberty likely has a small head gasket leak now...but it just keeps running. They owe me nothing and I'd buy another 08/09 Commander with the 4.7L if I could find a mint one.

[@dragonrage7]

As a owner of a 212k, 3.7l Dakota, I can tell you it is not the engine I worry about, it's the drivetrain! Engine runs like a watch, no missing fluids and great response and mileage. Already did the U-joints due to clunk, carrier bearing, rear wheel bearings and a pinion seal. I also had to adjust my pinion bearing preload during this servicing. Now as we get to the transmission that is where my trust wavers a little... the 42RE isn't outright bad but not the best thought out. The "adaptive shift" plus the "shock-absorbing" torque converter thing causes more harsh shifts than it seems to help during those times it was intended for. Tows okay.. We'll see how long it survives, but I know the engine has another 100k easy. "oil is cheap, engines are not!"...

My father has one of these engines in a Jeep Grand Cherokee. '06 if my memory serves. It has about 303,000 miles on it.

[@dazzle3096]

Had a Dakota 3.7 in high school and couple years after… I redlined this engine everyday for miles sometimes 15 min lengths. Traveled to every major college in my state etc Water pump, tons of wheel bearings, drifting dirt roads b4 school, cracked headers were replaced under warranty. Also had a cat rot out on me. Same trans some how. Always manual shifted to hold out the rpms. 😂 Sold here running 240k I have a 5.7 gets treated the same way for 200k and going.

[@evebrassard3105]

The skits with chains, guides and water pump crack me up 😆🤣

[@HappyHarryHardon]

Skits?

[@evilanglin8038]

I didn’t know about you until today. Great content

[@michaelrini3654]

You seem to be a bit of a clucks dropping everything! Its very entertaining. I am a retired mechanic who worked at Jeep for 11 yrs. If you did the basic service these motors would do pretty good!

[@harmonicadude4732]

You should try to make a complete engine out of a bunch of would be junk parts from other engines and see how long it lasts. Use “intact” wrist pins, “maybe straight” rods, slight “malice in the combustion palace” pistons, and “totally resellabal” water pumps.

[@aland7236]

"Junk in the sump" is now part of my common parlance. Thank you.

[@waldojim42]

I had that engine in a Raider with a 6sp manual. That combo did me fine for quite some time. Regular maintenance and it ran like a top. Don't remember how many miles I had on there when I sold that truck. Only one I regret trading in though. The next 2 replacements sucked ass.

[@Poorexampeofhuman]

I got a 4.7 powertec V8 with 294,447 miles on the odometer. Still running strong enough to smoke the tires. It's by no means the Magnum 5.9 in my 1999 Dakota RT but it does have decent power in it does move pretty well and gets crap gas mileage. I can't complain only thing I've ever done is change of water pump spark plugs and a battery still has the original serpentine belt on it

[@TechMage299]

Im so glad the chain guide conveyor belt is working as intended

[@davidmotion7555]

Always entertained by your videos Eric. Keep them coming! What is the brand of the work light you use in your videos? Thanks

[@johnperkins7179]

It's been a month of Saturdays since we have had a good dipstick battle. Excellent!

[@Howdy76]

I WAS JUST IN THE LOU. Saw the Arch and all. Happy Happy Joy Joy

[@scooterpickle8625]

I owned a 2003 Jeep Liberty Renegade with a 5-Speed and that 3.7L "Minivan motor". I had that Jeep for over 10 years and 163,000 miles. Still my favorite vehicle ever. For the record, I never had to replace a window regulator or a LBJ!

[@ChickenC0re]

The minivan motor was the 3.8 Chrysler put in the Wrangler. This one was only fitted to RWD biased vehicles.

[@davecaselli1957]

2002 Liberty, about 180K miles. HAVE replaced all the window regulators AND a left lower ball joint AND right upper ball joint/control arm. Still think it hasn't been bad. Keep oil in it.

[@MrKingdavis13]

The humming like a doctor inspecting behind the timing cover would be funnier if you lifted up on a tensioner and told the engine to cough. Lol

[@RS-vu3df]

Hmm, what I miss is a close inspection of the rod bolts. They could have told you if there were signes of fatique. The engine was indeed poorly maintaned, but,to me, it did not fail to oil starvation. I think most people are interested in the a thorough cause and effect analyses and so a clear construction of the destruction-movie.

[@metalted6128]

Look how clean the outside of the block is!! I learned 20 years ago, buying a junk yard motor, that was oily and dirty, wasn’t over heated. Over heated engines, the oil and grease is cooked off, the exterior of the engine. May be nonsense, but, I’d rather fix oil leaks, before installing a used engine, than one that requires machine work. Cause of warped parts.

[@firstlast---]

Ahhh I wish I knew that a few months ago. Got a "good deal" on a low mileage "running" engine that ended up having a very blown head gasket. Coolant pooled in one of the cylinders and rusted the bore. .20 over, freshly decked and new heads. Runs great now

[@alexdel-toro323]

Got one in my nitro it’s a jasper previous owners original locked up at 210,000. Bought it for $500 in perfect condition other than blown engine. Had some XD rockstars on it. I put a jasper engine in it and 2.5 inch lift. Cut the cats off no resonator just a flow master 40. A little loud but I’m young and it sounds decent. My mustang gt and ram sound better but I love my nitro. First car I bought on my own

[@at_omic8578]

I'm selling my 3.7 Liberty Biberty right now actually, ironically the engine is the only part that never gave me issues... just everything around it. Always wondered what they looked like on the inside. Certainly one of the MOPARs of all time

[@shardsprivatechannel]

i have A jeep with the 4.7l, and when we got it, it was taken care of poorly and was really sludgy. not as bad as this, but it was really varnished. had to doctor it up to 149k mi when it dropped a valve seat in the driveway. (it did so rather peacefully and did it on a friday...letting me figure out plans to get it to a shop) the whole jeep in general was mechanically taken care of like crap by the prev owner (every fluid stunk and was eithr burned or WAAAY too dark) so..its hard to blame it. ive put a new motor in it now, and its mostly on offroading duty. but in that aspect its been great. nice and torquey, never have had overheating issues..and its worth the silly looks i get on the trail when i'm with a bunch of wranglers

[@shanestergamer6196]

Liberty Biberty got me 🤣 Haven't seen a good dipstick fight in a while! One engine I thought of to tear down but the video would be really short, ONLY if you can find one is a 1.0 3 cylinder from a geo metro. 3 cylinders of FURY. 😂I just pick up one of those a couple of weeks ago and it runs and drives.

[@dwalmop2]

Don't remember if I've commented on this before, but I'd like to watch a teardown of that Audi v6 in the background!

[@thehammermanduke]

Definitely a great training video. Thanks for posting.🎉🎉🎉🎉🎉

[@joashaguilar8608]

Never been this early to miss the water pump segment of the show

[@Catfish4000]

Looks like AMC/Jeep really liked Ford's Pinto cylinder head so much, they made a V6 and V8 version of it

[@carson01XJ]

I like the 3.7 in my 2010 Jeep Liberty quite a bit. Seems like a perfect engine for that vehicle. Unfortunately a cheap autolite spark plug insulator broke inside the engine and damaged one of the cylinder heads. Thought it was the head gaskets at first, but no. Now with new a new head and head gaskets it's running great at around 160,000 miles. It also had an oil consumption issue which mysteriously disappeared.

[@twillison8824]

I had a 3.7 jeep that had 240,000 on it when I sold it. Currently driving a 4.7 Durango with 290,000. They're like anything else, all depends on how you care for em.

[@elianbarajas2869]

We have one in a Dakota, it runs pretty smooth and they're easy to work on, it doesn't make any power. We can barely get up the grapevine in socal. At 235k it burns a a quart every 1500 miles. (Probably because of the 10k mile OCI)

[@drewhh6821]

I appreciate the fact that they made the passages on the head gasket look like a face between each cylinder

[@fuller9x]

Gotta love the unset JB weld and then the weekly visit of Uncle Rodney and Aunt Beryl

[@WorthlessNickores]

I find it hilarious that people get upset over chunking the water pumps in the trash. No intelligent person would reuse a water pump and risk it being the failure point of an engine rebuild when they aren't that expensive and make as much sense as replacing the thermostat while you're in there. When I rebuilt my 04 Passat's 1.8T AWM engine, I replaced everything I could afford to replace and all must change items like tensioners etc. Turbo, all wheel drive 4Motion and 5 speed manual are a fun combo.

[@thomasfletcher760]

I had a 1988 Dodge Dakota with the 3.9 V6 , no overdrive , no cruise control , sold it with 400,000 miles on it and still ran great .

[@adamtrombino106]

The old push rod 3.9s were pretty much gas oil and go. Change the oil and coolant and not much would go wrong.

[@edifyguy]

The water pump was taken into protective custody by the prior owner. Clearly, it was the only part of this engine which actually mattered to them. I intensely dislike people who intentionally blow up an engine. This could have been rebuilt before he grenaded it, but he thought it was more fun to destroy it. Wasteful and absurd. But, it was interesting to see the inside of this engine. As you said, they are everywhere, and I had wondered what they look like inside. Thanks for sharing.

[@gt1900b]

That oil pickup certainly has the smashed angry face going on. Reminded me of one of the other laser robots from Short Circuit

[@dannyoaks85]

Man it's been a while since we've had a good dipstick tube fight. Good show 👏😂

[@timmason161582]

I had Liberty with this engine and sold it with almost 300,000 miles. never went more that 4500 miles without an oil and filter change. All recommended maintenance done on schedule. they will last if taken care of.
