Today's video is something a little different. This 4.0L Nissan VQ40DE was claimed to be a bad engine. This engine is from a 2010 Nissan Xterra with 203K miles. While driving across the country, the transmission failed from a breached transmission cooler inside of the radiator which allows coolant and transmission fluid to mix and enter the transmission ruining it. The owners declined the repair and sent the Xterra to a salvage yard which upon dismantling noted that the engine oil looked like milkshake as if coolant and oil mixed. Thats the story I was told and it didn't make sense. Sometimes in the salvage industry, there is waste and I do my best to avoid that. Thats why I had some doubt about the details of the story and why I decided to look into it myself. No harm in verifying information and best case scenario someone was wrong and I get a good engine to sell(and hopefully get a bad one in return!)
My name is Eric and I own and run a full service auto salvage business. Part of our model includes buying and dismantling core and blown engines to salvage the good parts. We do not rebuild engines, merely sell 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! -Eric
You surely do more than 99% of engine resellers to make sure an engine is actually good before you sell it. It is really impressive!
Collab 😂
I agree I would have no problem buying an engine from him
I would say he does 99% more than 99% of engine resellers.
Which is great, it's heartbreaking to install an engine only to find it's no good.
Ya that has to be such a let down and waste of time :-(. I feel like even with his checks there is still a small chance something could be wrong but ya it's about everything you can do to check he does @@robinsattahip2376
Eric, this was extremely interesting and educational! I got more out of hearing your explanations and seeing your diagnostic process than putting together the bread crumbs from ICE carnage. More of this, please.
Was kinda hoping that it was bad, two for one 😅
We have owned our 2008 Xterra since new. 203k miles on it now. Been the best vehicle I've ever owned. I changed the radiator at 100k to prevent the milkshake of death.
Our 2019 Armada on the other hand has been the worst. 89k miles and has already had the shortblock replaced and is having the transmission replaced right now.
do the 19 and 21 titan use the same motor and trans?
Nissan is really hit or miss in general. Some cars are bulletproof, some are ticking timebombs. Hard to tell which you're getting.
@@jokerdog4598 Same engine, different transmission.
@@AdirondackHomestead you called it!
i owned a nissan, would never get one again. worse i heard there going even farther down hill, mitsubishi is almost better than them and theyre almost legendary. hopefully my new toyota lasts a good 20 years
It's really good that you value your reputation enough to do all those checks. I know some yards just sell everything they get and don't care.
It's a business practice to be proud of, and some great content for us. Thankyou as always!
Hear hear 👌
Thank You I'm 67 and do my own wrenching and you just taught me something.
Yay! Finally, my motor on the channel! Have an 06 frontier with 194,000 6spd manual. Runs beautifully. Replaced cats, hoses and intake ducts, coil packs/plugs, intake manifold gasket, power steering plumbing, oil cooler gasket, heater core plumbing, alternor bearing, and tensioner pulley. All routine maintenance maintenence and runs the same as when I bought it.
SAME HERE 06 NISMO CREW CAB. I change the oil on time use synethic. have never done plugs or had any other problems(fuel guage) I have 190k kms. maybe its time to do a tune up...maybe not?
I have an '05 Frontier SE 4x4 auto that just turn 60k miles. Been a great truck so far. Just replaced the first round of serpentine belt and pulleys based on age.
@@TherealjmhinkleAn 05 with only 60k miles? and 4x4?
Please let me buy that sir, that’s awesome.
@@Bryan-kl5rr I inherited it when my Dad passed away. He bought it new. I'll pass it on to one of my kids.
Hi Eric. I was researching some info on 2.0 ecoboost engines and found 2-3 year old video where guys who specialize in Fords in Ukraine in city of Odessa showing your video, not all of it but comenting and explaning it in longevity and durability of ecoboosts dedicated series. I was watching and guy goes Eric this, Eric that...
I was like ... wait a minute! I know that Eric, those gloves look awfully familliar!
Great video! It's fun watching Eric's commentary on blown-up engines. But it's also nice to see something perfectly usable being saved from the crusher.
Eruc - You can have mine. The Colony TX. 2006 Pathy, 248,000 miles. No milk shake. Massive failure though! Like six sledge hammers. Cracked head or blown head gaskets too. 35 to 99 psi between is all it would do on cranking. Couple plugs that were new 8000 miles ago not looking good. Timining chain issues i assume too, like slapping noise. No oil leaks though! Perfect tear down engine.
Yay! My engine. 2008 Xterra 4.0VQDE just passed 250,000 miles. Runs smooth, strong doesn't use oil. Run the transmission fluid hoses through the transmission cooler and loop off the radiator and no Pepto Bismol issue. Did mine at 87,000 miles, tow frequently with no issues. Run synthetic oil, nissan filter change every 5,000 miles.
With valve cover off, use a light hammer and some nonmetal rod and tap the bucket tappets (valve spring retainers on rocker arm valve gear engines). This can dislodge valve/valve seat deposits. I've tested long stored engines before and done that to get a better idea. Rust on seats can make them leak like the valves on this one and the smack therapy fixes it right up.
I've done that to when I get an engine that has sit or something like that.
I've done this in the past too. I 100% agree with you on this.
I for one would like to see more of these kinds of video, especially since I can learn something during the week! Thank you Eric, for all you do.
Glass cleaner (Windex i have used) bubbles alot and makes finding tiny holes in tires really easy too. i didnt know this trick for valves. Keep up the good work!
Thank You!! Waiting for ages for you to rip apart a 40!!!!!!
VQ40 is a strong engine, few issues on first ones like secondary timing chain tensioners and catalytic converters. After 2009 it’s perfect
2010 was when they moved to updated tensioners and guides and also updated the radiator to fix the transmission cooling problem. After 2010 is considered when these engines were the best and known to easily hit 300k with regular maintenance
These diagnostic videos--also like your getting a non-running car started--are especially satisfying. A nice addition to your oeuvre. Cheers.
Though I delight in seeing the catastrophic teardowns, this was satisfying in a different way. Kudos for being thorough in checking engines for future customers.
Love those VQ motors. I had a 95 Maxima with the first VQ30 that motor was absolutely indestructible. That motor had 382k miles on it and ran perfectly when the car got totaled.
Hey Eric..... I absolutely learned stuff from this video...... which is one of the many reasons I seek out your latest videos...... you speak in common terms...... you stay lighthearted and humorous... keep up the great work!!
The fact that you don't have, or get these engines in very often. Tells you just how good these engines truly are. I have a 2008 with 225,000 plus miles, and so far so good. 🤞love this channel.
These are pretty reliable engines, once you get past the timing chain tensioners that we’re updated around 10’-11’ and the cats that get clogged and the particles get sucked back in the engine. Yes it’s possible especially with these. I’ve put around 400,000 miles combined on the 2 I’ve had. SMOD is a whole other issue that can be easily addressed, rerouting the lines or swapping radiators. You can find these all day for 2-3k with bad transmissions or before they let go, and do some preventative maintenance. These Jatco automatic transmissions are much better than their CVTS and as far as I know have no flaws. The radiator itself being the culprit.
Yeah I agree, these are generally good engines with the post-2010 timing chain upgrades. They make decent power, pretty reliable, they’re not too bad paired with the Jatco 5 speed. I’ve always viewed them as the Nissan counterpart to the Toyota 1GR 4.0 that was in the Tacoma’s/Tundras/4Runners.
@@Fraserfirrr Though if I had to choose, I’d take the 1GR both variants over the VQ40. They seem to have less issues imo. I’ve owned a Tacoma with one it was much smoother and quicker to me.
@@elonsus9747Toyota sells old engines that aren't powerful in their truck chassis. It's most definitely much slower than a VQ lol. Especially if you delete the VQ cats.
@@TheGuruStud My 13' Tacoma V6 would eat both my Pathfinder and Xterra 4.0's. But that's because they're old. In their prime they'd put up a fight. The new Toyota trucks and SUVS use turbo V6 and I4's that would wipe away the old motors from Toyota.
2008 Xterra had the Trans cooler rupture inside the radiator, transmission junk, motor junk. Coolant and transmission fluid do a number on the cooling system
3 minutes in and I got a bad feeling I'm not seeing this in pieces today...maybe in another 150K miles, maybe...
I was watching this one with my 4 year old daughter, she COULD NOT get over the fact you had a Snack Pack pudding case on the shelf. Thanks for making her day lol.
I love the leak down demonstration. I’ve been working on cars for 25 years and have never done one. Nice to see it before I need to do it.
I want to get away is the old Xterra commercial song from the early 2000’s is what I always think of this vehicle. Great video Eric.
Great educational content -also and perhaps above all the “I hate waste” part. I’m also joining the “more of this” brigade!
You did a good thing Eric. You are a good man. You never want to waste or sell a bad part or engine. By investing your time and knowledge, you saved an engine from an unnecessary death, and hopefully it can help someone who needs one. Hope you and the family had a good Christmas, and hope you and the family have a good New Year's! Looking forward to more videos from you!

And here I was thinking that it was going to be an early teardown. Silly me. Very interesting. Nice to see the steps you take in checking an engine. Keep up the good work.
So glad you finally came up with a VQ40, I've been waiting forever to see what they look like since I have a '16 Frontier. That leak down test sounded straight out of the baby monitor on Signs! Thanks again for all your videos and keep up the awesome content!
Grab a large sized razor and cut the oil filter media out around the edges(flanges). That's how we used to check the spin on filters from aircraft engines I worked on. Did the same thing with race engines after break in, looking for, as you have ingrained into my vocabulary, the "forbidden glitter"...
I love videos like this one. Even if I'll never perform a leak down test myself, at least now I know what it means when someone says an engine has passed one.
Finally my engine on your channel. Id love to see a full teardown someday. Glad to read all the positive comments about this engine. I hope to get 200k+ eventually although living in the rustbelt is going yo make it hard to keep my frontier together even with yearly undercoating.
🤙
Same here, though with a VQ37VHR in my daily AWD sedan, and the rustbelt up here in Ottawa/Eastern Ontario should be renamed to something more serious. The salt is insane, it's the deathbelt. Krown every September.
Greetings from BrainDamageBBQ, Joel and I are watching right now!
Thanks, Eric!
Lawrence
These engines go wrong when you get an air pocket near the rear cylinders and the headgaskets do pop. The fix is to over fill the coolant resi, keeps the system bleed
I enjoyed this video a lot. You’re the first person I’ve seen to inspect an engine to see if it’s good engine to sell. This should be common practice with all salvage yards.
Another great video Eric. I love your honesty in this business how you test things as much as you can before you sell it, and if you have any doubt, you don't sell it as good. If I never need used parts, I'm definitely checking your website.
Interesting video. That's gotta be a first that the water pump makes it out alive. Also surprised that the 'tighten' button on your electric driver still works after so little use :)
This was really cool.
It looks like the timing chain adjuster is extended out a fair amount, which is expected at 200k miles.
I'm not an expert on these motors, but if I bought it, I would perform a full timing chain service with OEM parts prior to installation.
Thanks for the video.
Used to own an 05. The other fun thing you need to look out for is the oil gallery gaskets blowing out behind the timing chain. Mine had blown out a small section right at the bottom, which was causing a low oil pressure issue. Not low enough to trip an idiot light, but low enough to register on a proper gauge and eventually cause issues. Fix is to pull the timing cover and replace gaskets. I did the timing chain and water pump while I was in there too.
Buying a new car is not an option for alot of ppl,you provide a much needed service for ppl that would otherwise be in a very bad situation, I love these videos and this channel,keep up the Great work.merry Christmas and Happy New year bud.
This was quite astonishing! Eric, I think this is the first time I've ever watched you put things back onto an engine!
Great video, BTW. I've heard of leakdown testing, but I never realised how much information it could give you.
First time I have seen that leakdown procedure. (I am not a professional mechanic) I watch to learn about engines and procedures. Well except for throwing parts into trash bins.
I bought a 2011 in 2011, with this very engine. It ran like new for 177K miles until someone stopped sideways across the HOV lane around a blind corner and rolled me. I wish I still had it,.. it was an amazing engine for me,.. and no milkshake of death at any point. There's a small hose under the intake that blew one day and left me hauling her home on a flatbed,,.. in 9 years that's the only time she left me by the side of the road. Replaced all the hoses and she ran like a top,.. what a GREAT engine that is!!!!
Eric, you missed one important further step. Once the valves are closed and you're at TDC, slowly continue to rotate the crank to check cylinder wall/ring condition. If there's oval, or other wear of the walls, it will show up as high % leakage on the gauge.
I would have thought run the camera inside the cylinders to check the walls for scoring
I absolutely LOVE the sound of a hopped up VQ engine. They sound so much different (to me) than any other V6, not so raspy. 👍
Yeah. '00 Maxima SE (2006-2010), '06 G35x (2010-2016), '06 Z33 GT coupe (2013-2020), '13 G37xS sedan (2016-now, daily) and '07 Z33 roadster (2021-now, wknd car). 17 years of VQ'ing around, bout half of that with Borla / Stillen / Invidia exhausts and HFCs, it's been quite the enjoyable ride. Over 350K miles racked since 2006 when I was 21, biggest repair was a rad replacement 2 yrs ago on my daily G around 100K miles... VQs fvkking rule man.
And when you check the coolant system during a leak down check and you get bubbles coming out, you probably have a bad head gasket (or bad mating surface(s)) or worse, a cracked head into the coolant passage. Thanks for taking your time to publish this video for use to learn and enjoy. 😁
Not "use" - "us". Oops!
I like those out of the usual format, and we get to learn about typical failure points, nice! 🙂
The usual teardowns never get old, but this was really fascinating and educational. These 'a little different' or 'behind the scenes' videos of stuff we haven't seen before are as interesting and enjoyable as teardowns of the rare/unique/bizarre hard-to-find engines that we hope to see someday. I think it'd take a VW W8/W12/W16 teardown to top this.
Just got rid of an 06 xterra x 4×4 with the 6 speed manual. Best most reliable car I've ever owned. Was sad to see it go but it served me well and as such, she should be proud for the service she gave. I'll always have her pictures and I honestly wish her well in her future endeavors.
Been messing with cars since 1967 and this is one of the most informative videos I have seen. Thank you!!!!
I really like the explanation about crap getting in the valves and seats when an engine is not run for a long time. Now I understand part of the need to run them everynow and then if not in normal use. I always thought the battery will drain, but never the engine will get into trouble just standing there. Thanks a lot. These type of videos are very much appreciated.
Same thing happened with our 05 Dodge 3500, 5.9 diesel. The coolant mixed in the transmission cooler. Only the coolant and trans fluid was mixed. After the transmission was rebuilt, they spent days flushing the coolant system till it was clear.
Looks good. No metal, no coolant in the oil. Excellent leak down results. I think you have a good engine!! Hope you had a good Christmas. Mine was quiet. See you next year Eric.
Ive had 3 Xterra's with VQs 205K on a '07, 180k on a '10 and 130k on a '13. Even with full bumpers, titan swap, 35s 4.10s and full steel armor the motor still has more than enough on and off road. Yes they have their quarks but if you take care of them they'll last a good while.
Have the same engine in my '06 Pathy. The biggest job yet I've done was replacing the timing chains, guides, and tensioner at around the 155k mark which was roughly 2 years ago, so I was a bit surprised to see the original timing chain at 203k .I also replaced the radiator well before the 100k mark to prevent that PMOD issue you mentioned at the beginning. I liked how you walked us through a leak-down test and explained every rationale behind it.
These are pretty hearty engines, sure they chug a good amount of oil but a little PM goes a long way.
When you have a radiator fail in that manner, you'll get coolant in the ATF which destroys the trans, and ATF in the coolant, which doesn't necessarily destroy the engine if caught soon enough.
I had a 08 Frontier Nismo for 13 years. Best truck ever! Glad to see this engine on your channel.
Amazing job educating everyone! From the viewers that have never turned a wrench, to the techs or former techs like me! I definitely learned something watching you do the leak down and then fixing the issue without disassembling it completely! We always did a bg treatment in the intake to clean out carbon b4 running a leak down to rule out carbon build up ! On my personal vehicles if I’m at those miles and having a need for a leak down I will usually pull and rebuild the engine as by 200,000 I’ve got other things like pesky oil leaks and what not! Or it’s a good excuse to hop up the engine while rebuilding without the wife ever knowing lol!😅
This is a new type of vid for you - I like it. Shows integrity, shows perspective, and lets me know how to test an engine. I'd watch more if you're willing to make more.
And it is a wrap. You are definitely the BEST person to buy used and reliable engines from,due to your personal morals, and you are definitely a square man. I'm gonna do my best to promote you.
I love your diagnostic videos as much as the teardowns. Midweek, diagnostic; weekend, teardown. Sets a good cadence.
Good job inspecting on the engine before sell it Eric!!! It’s good business with people
Very interesting video, Eric. The teardowns are my favorite, but I wouldn't mind seeing more content like this also. Great work.
thank you, just got an xterra a couple months ago and looked to see if you tore one down, said damn and moved on. now here we are. great video, thank you for your dedication. please, please, please do a gm 2.2 (older ones not ecotec) teardown. young guys with s10s (and cavaliers) as first vehicles would be grateful forever, and so would I.
Hi Eric, I have done engine work since my teen years, I have seen engines run after putting a leg out of bed (put an inspection port adjacent to 4th big end) I have seen a diesel melt the pistons, they ran all the way to the muffler, that one didn't run again. Engine from the same vehicle, twist piston off and rip everything out within reach of that con rod. Again same vehicle the con rod was so hot that it bent around the crank and the piston went out the bottom taking the oil pump with it, that engine did actually run again. This was a rear engined bus and over revving was a problem especially when the drivers don't own the vehicle. I am now approaching 79 and just enjoy seeing someone else work on these engines, so keep up the good work, and God bless, I was especially interested in the equipment you used to check this engine out. Ted from down under.
Great job! Getting cars and good parts back on the road is a fantastic calling! I love it whenever I get that first drive after months or years of something teetering on the edge of scrap. Nicely done.
...and now I know how to properly do a leakdown test. Thanks!
YEAH a Nissan episode! I love these
My frontier with this engine has been the greatest vehicle I have ever owned 194k trouble free and been road-tripped and also worked hard multiple times. Now it’s my daily and I take it easy and don’t work her as hard but she’s still solid. Been my favorite truck I’ve ever owned by far simply because of reliability
One of the best videos yet. Love the diagnostics and solutions. Is this the greatest car show ever?
This was good and really useful to see your process of discovery. It can be helpful with troubleshooting a non-running engine.
Love the variety of recent videos. Leakdown test, boroscope,etc. Fun to learn new stuff
I come from a generation where we never thorough stuff away.
Make do and mend.
Engines and components were not as reliable as they are now, but there were local shops that would fix everything cheap.
Hey Eric,
I really enjoyed this look at your procedure to determine if an engine is good, bad or ugly!
I’ve been watching your videos for about 2 years now and this was the first that I’ve seen on this subject. Thank you!
I always enjoy your sometimes cringe worthy slip ups and would love to see a few best of Eric’s brain fade moments “caught on tape” episodes.
Also, maybe some shorts on small engine carnage for fun.
You need to invest in some white lab coats and nurses uniforms with your logo on them for your autopsy tear downs and you or your wife as the surgical nurse assistant for a cosplay Halloween special!
As always stay safe and healthy!

That leakdown on a cold, setting engine was very good. We did them all the time on aircraft engines when I was still working in general aviation aircraft maintenance . At the time we had 65 aircraft that averaged 100 hours every 2 weeks, a engine service and inspection is required at 100 hrs and a leakdown test is a part of the inspection. Ours were aircooled and done slightly different but yes on a warm engine 5 to 8% was normal and when it hit 10 it was a sign of change somewhere. The logbooks would have a record of every leakdown done so you could see if there is a trend or is it sudden. We used leakdown tests and oil analysis to help determine when to pull an engine for overhaul. They are very useful tests. Thank you and be safe.
Good to watch and see.
Hey Eric, you may consider an engine tester. Basically it's just a high torque 240v motor that attaches to your engine by the crank pulley or you can use a bolt on flywheel pulley (some people think the crank pulley can't take the force, i don't agree). I'm an engine shop and it's a great investment, that said the one that I use the most is one I made myself. All it needs is an engine cradle (you can use a wooden crate, and ratchet the engine down) and a belt from the motor to the pulley. I'm running a 3 phase motor out of a Bridgeport mill with a 3:1 gear reduction, tentioned on a pair of steel square bars with a threaded rod to tighten it up., it revs at about 700-1000~ rpm depending on the specific engines pulley, but that lets me make sure i have no leaks, no noises, good oil, compression etc etc etc.
Maybe you don't need it, but for those engines you can't turn the key and run, it would give you a way to test them. I also have a complete test stand and engine dyno setup, but it saves me a lot of headache of finding a coolant or oil leak at run time when it's a nuisance (and cost time) to fix.
11 days, Guess I've been Busy! Kind of a nice divert off the beaten path on this video. Diag and solution was well worth the effort!!! Be well Eric! Looking forward to the next!!!
One of my customers leased his 2008 Xterra to a student and the engine blew up. Then he found a "parts" 2006 Xterra with a supposedly good engine for $500. Leased it to the same guy... And a month later he blew up the SECOND ONE!! Both beached whale ZTerras are still in his driveway. So if you want a teardown candidate I know who to call 😂
I'd love a blown up one to actually teardown!
@@I_Do_Cars the guy is hurting for cash so make him an offer... Both trucks are road worthy, just bad engines 😉
Shoot me an email, I think I can make something work. Mazdamiester@gmail.com
Fascinating! The last time I saw a leakdown test was in the eighties. Weird watching you put something together. Great video!
27:15 Am I actually starting to watch Eric reassemble an engine? Must be a first. :) Thanks for your videos over the last 12 months and I hope there are many more in 2024.
I know it’s not quite the end of the year and we get one more video before the end of the year but I gotta tell you watching your videos again. This year has made my Saturdays and a few Wednesdays quite nice and enjoyable and I really do appreciate the time you take to make the videos for us to watch.😅
Really like these different kinds of videos, especially the inspection aspects!
When I saw you putting the valve cover and bolts back on , I though I was watching the video backwards! I'm only used to seeing you take stuff apart
when you cut your filters apart use a razor knife to cut the filter media around under the end caps and cut one of the pleats and you can just peel it all out you don't have to cut the end caps off of the center tube to get the media out.
You make engine architecture and failure analysis educational entertainment, thanks for your efforts and talent. I'd love to see a Mercedes M274 tear down.
Thanks again.
Nice to watch your diagnostic procedures unfold. Good show, and a good save!
So... rookie question here. What kind of glass cleaner did you use? I have to believe that some of it got past the valves. Won't the "remnants" cause surfaces in the cylinder to rust? Or is it not of consequence?
I have almost 250k miles on my VQ40DE. Some of the peripheral bits are starting to act up, but given the price of trucks these days, it gets fixed.
Thanks for the leak down test, I haven't seen one explained before.
Cat litter buckets come in handy for lots of things....
Eric thank you for this video! I really enjoy watching you tear them down but seeing you go through how you diagnose an engine was very informative for us weekend garage mechanics. Keep the great content coming!
I was ROFL @ 22:53 when you went tappy tappy tap "That's not going anywhere!" I guess we watch some of the same UA-cam channels LOL!
I like the process of you checking out the engine. Different from your normal video but informative. Someone will get a decent motor in the process. Very good.
"I hate waste" - Man, I wish more people had this philosophy. There ARE some things that are worth repairing and saving.
Hey Eric, thank you for showing us the processes you go through to evaluate an engine. I found it really interesting. I hope you can sell that one and make a decent $ on it. Cheers!
Late to the game, but I would love to see more of this content as well. Teardowns are awesome, but so is seeing the processes used to tell if it's bad in the first place.
Very good video and test.I just bought a 2012 Pathfinder with the 4.0 thats been parted out.
As a Nissan tech the VQ 4.0DE.... Thank you for the great videos!
Eric, best video ever....really informative...thank you
