Sorry about the late start! My video converter let us all down.
Today I tear apart a 3.5L VQ35HR from a 2007 Nissan 350z. This engine, unlike most of the engines on this channel, was from a VERY wrecked car and suffered massive damage as a result. I tear this down to discover what made it, what didn't and the extent of the damage.
My name is Eric and I own and run a full service auto salvage yard and part of our model is selling good parts off of bad engines. I get these bad engines from other salvage yards, or they are my customers old engine after they bought a new one from me. We salvage as many good parts from these engines as possible and the rest get scrapped in their appropriate material bins.
You can catch a new teardown every Saturday night and sometimes a bonus video midweek for an update on one of my projects.
As always, I appreciate all of the comments, feedback and even the criticism, catch you on the next one!

“I’m going to attack that a different way. By ignoring it.”
Story of my life right there lol
Me too. My wife hates it
Sounds like a plan. Sometimes it is better to not rush in - I have had a good run of procrastination paying as of late 😆
It's funny, but sometimes creative inaction is really the way forward. Can't wrap your head around a problem? Distract yourself doing something else and it's surprising how often the answer will come to you.
Brains are funny. Pizza cam.
Judging by the plugs, it ran well on it's final trip!
It’s always running great before it blows up.
That engine has all the signs of good maintenance and a healthy amount of Italian tuneup. The windage from frequent high rpm keeps the oil deposits from building up, running a high quality synthetic oil doesn't sludge and varnish very easily, the intake ports have a nice healthy fuel washdown pattern, the back of the intake valves are clean, and the dry areas of the ports have minimal buildup. It would have been interesting to see how the rings looked as far as how clean or fouled the grooves and oil rings were, as hard driving tends to keep them relatively clean as well.
@@hdrenginedevelopment7507 I can confirm that it's impossible to own a HR and not redline it regularly
I actually flipped my 08 350z VQ35HR back in 2012. Now one of the cars I own is an 08 G35S HR at 216k miles its tuned and my wife enjoys driving it. Thank you GOD for letting me survive that crash.
You kept your guardian angel on their toes! Glad you are here still posting.
Is it just me, or is that sound of high- torque fasteners being cracked off lovely?!!
Late to comment… but yes. The sounds of the pneumatic tools sped up sound crazy cool
@@TheSleepyMechanic0524 Love engines. I ride bikes and the thought of having to ride a 2 wheeled milk float fills me with dread.
I wonder why each head bolt sounds like it cracks twice when loosening with the breaker bar? One as it starts to move and then one more time like 1/2 a turn in?
Makes me wonder if it was a fatal wreck. Cool Viddy. Oh, and because YOU asked, I want to see a Mitsu Mirage 3 cyl teardown. Peace.
Well, thank goodness we never see the other side of the firewall, lol...
I used to work for an old body repair man who dealt with salvage rebuilds. I asked him one time how he handled dealing with the blood and other signs of human suffering, thinking I would get an answer about how he handled his emotions.
Instead he just replied: “Vinegar and a garden hose.”
@@brianjay692 well hes not wrong, i used to haul copart auction cars that all had biohazard tags allnover them.
Considering the damage to the bellhousing, I'd say that engine was halfway into the passenger compartment. If anyone survived, they must consider themself or selves very fortunate.
Double autopsy
I always wondered what they meant by a 7/8 cam. Now I know!
And I love it when Eric removes the bolts from a destroyed part (like this head) in the proper order so as not to warp it.
Always do it the right way, even when you know it's pointless to do, because keeping that good habit and attention to detail carries through to the rest of your work. :)
Good work habits
good habits are good
I think the point to take here is if you don't change your oil, you get variable length rods and piston mcnuggets. If you do change your oil, you get them newfangled cracked cams and a nifty timing cover access port. That's why I don't use Amsoil. Instead I use Nozoil. Because no oil = no problems!
This comment. So true, but so wrong. But so agreeable
LOL
Those harbor freight breaker bars have certainly held up well for the dollars spent. Earned their keep!
Interesting to see inside the variable cam mechanism and just how many degrees this thing can move! I didn't know it was so much.
I honestly thought BLUE was going to be a lot busier today.
Great tear down.
Congrats on the new addition to your family
It wasnt the vq37vhr teardown that i wanted to see but its damn near the same engine lol. I appreciate your channel and these vids that you do man, especially when you throw parts out of frame and here them tumble hahahaha. Keep these tear downs coming man im learning alot from you and them.
I thought the same thing when i saw the thumbnail😭
You could reuse the tty bolts as the collision squished the bolts back to new length
I have seen that type of damage from vehicles that were thrown around in a tornado.
The way the trans is damaged looks to me like the vehicle was traveling way faster than it could be blown around
@@yeahitskimmel I said I have seen it because I have personally seen it. Cars have been thrown miles by tornados. The last big tornado that hit my area had a wind speed of 210mph. The last tornado that hit my house had a wind speed of 301mph.
There isn't enough mud packed into this engine for it to have been in a tornado but the level of damage is similar.
@@c0c0asauce Dear God...where tf do you live? In the Wizard of Oz?
@@rmp5s Probably in the Midwest.
@@rmp5s Ooooooklahoma where the wind blows real damn hard.
Being able to salvage a good short block out of that pile was super fortunate!
At first I was VERY disappointed that you did not upload a video last night. Watching the teardown on Saturday night has become part of my Saturday night routine. That said, I know that RL is way more important and this video was worth the wait.
Never seen a clutch and flywheel come off before the Bell
Small note that oil filter is larger than oem size. So this guy took care in his motor.
Hell yeah. 2pm in scotland. Thank you Eric
Yea.....All of a sudden I thought it was Saturday night instead of Sunday morning here in the states.
Was waiting up all last night too 🤣
Those loose pieces of the oil pan are actually ancillary pieces of the oil pan.
I truly enjoy your videos. You do an excellent job describing everything that you do, and you have a wonderful sense of humor.
I haven't watched every single one, but at least 30 of your teardowns and this is my favorite one, the Marauder being a close 2nd. Anybody can run an engine hot or dry of oil and mash the pedal until it breaks but this, this is a special kind of carnage.
Usually you are taking apart engines that are destroyed from the inside, this one was destroyed from the outside! I pray for the person in that car!!!
Best one in quite a while Eric. Always happy to watch an oil starvation or hydrolock, but crashes and car fires are not run of the mill. Lookig forward to the next unusual one...
Another fantastic video, Eric.
Thank you!! Loved seeing what my dream car’s engine looks like! Hope we never have to tear into it but at least now we have a little insight. Love even more that I watch these videos with the hubby ❤ #proudowner 2004 Fairlady Z
That was an awesome teardown. Thanks.
I was amazed it had exhaust headers instead of manifolds
Makes me tear up knowing another Z car is off the road. Every Z ever made was a great cat to drive.
I love driving cats.
Are they still making them?
@@user-lp7dd7dz9m yeah? 2024 Nissan Z at your local car dealer.
Same with everything on the z chassis long live Nissan 🫡
@@TheRealCCSmithAssuming you can find one. This motor specifically came out of the 350Z and the number of them still on the road are dropping because of kids doing dumb $hit to them.
Who would want that short block, many many people! Not much to get that engine making noise again.
As always thanks for sharing, cheers mate.
As mangled as that engine was, it makes me wonder if the driver is still alive. That must've been a high speed impact
It'd be a miracle, when the trans broke it had three places to go either down into the ground, side ways into the frame rails, or up through the thin body panels and into the interior of the vehicle....
It takes quite a bit to kill someone in a frontal impact. Like, way more than this.
@@lovelessissimo No it doesn't----just the force from a high speed impact alone can break someone's neck and kill them instantly.
@@justsumguy2u maybe in cars from 30 years ago. Nowadays with crumple zones, air bags, head rests, stretching seatbelts, and the fact that its lateral movement that breaks vertebrae and severs the spinal cord, the odds of survival in a frontal collision are very high. Fatal injuries due to frontal collisions are typically incurred due to internal bleeding, which can happen, but it takes enough force to overcome the other safety systems. And that much force would annihilate the engine compartment.
Now, a side collision is another matter. It doesn't take much of that to kill someone.
@@lovelessissimo I gotta admit this all seems so ghoulish and macabre. Unfortunately for me, it's all too real. I saw 2 kids killed in a 350Z in 2008 right in my rearview mirror. - Driver (who had been drinking) was speeding and rounded an S curve in town, went wide, driver jerked the wheel, overcorrected, the car slewed right then left and sailed across the center median, just missing me and T-boning itself sideways into a brand new Tundra behind me. Estimated impact speed about 130mph (Tundra 50mph+350Z about 80mph). Tundra was crushed to the firewall, its occupants sustained only minor injuries. The passenger in the Z had no chance, DRT. Driver was DOA at the hospital. It was a terrible thing to see happen, and I'll never forget it as long as I live. Modern cars are tremendously well engineered, but physics is still physics.
Keep taking these apart. So entertaining.
I appreciate the intelligent remarks. A nice alternative to some UA-camrs.
“I’m going to tackle this problem in a different way…by ignoring it.” Another great Eric-ism.
Thank you so much for doing this engine! I learned a lot!
Eric, I enjoy your videos immensely. I have recommended them to many people.
I always enjoy your videos
This guy does great work
Another interesting video. Thank you. I hope you find an editor and they do as good as you do. Congratulations on the baby 😊
At 14:12 I was convinced you were about to invent the first ever “wood cannon” launch into outer space. But getting the crank bolt loose was a good silver medal bonus.
Always love it when you say "that part looks pretty good" and then it crashes into the floor.
There are parts which are never reused (at least in the first world) because they are inexpensive wear parts which are very difficult to replace, hence not worth the labor to install a reused part.
34:13 Honestly surprised you didn't throw in a "That's what she said". You're slippin!
Eric, great video on the destroyed engine. Would love to see a tear down on the Nissan 2.5 that’s been used for around 20 years. As always, Thank you for what you do!
I’ve had a few QRs, including in a spec v I have now. I’d also enjoy seeing a QR tear down.
Thanks for doing a VQ!
It would be interesting to find all of the parts for a given engine build, where absolutely every part came broken from another engine. Build one complete engine where literally everything is broken. Make it an art piece. Put a thick pane of glass on top and use it as a table.
If it's all broken how does it assemble together??
@@MacPoop op is probably thinking about bent rods, bent valves, fucked up cranks and journals, scratched cams, broken chains, anyway, all that good stuff
@@TiagoSC So basically the 2022 version of "good used engine" 😁🤣
@@MacPoop mild driven, barely broken in, grocery getter, never saw 3k rpm.

Another great teardown video. Thanks
One thing you ought to do before you deem the short block "good" is to put a dial indicator on the crankshaft output flange to ensure it isn't bent there. That flywheel imparted a ridiculous amount of force into the crank.
The fact that it still turns over relatively easily means its likely "ok" since its not binding up in the rear main, but still would be good to check. I'd also want to check for cracks as well in that area, but it might not be so easy to inspect without fully tearing it down. I suspect what broke the trans off was having the front of the motor impact whatever the car ran into which then turned it at an angle relative to the trans, which snapped the bellhousing. Amazing the short-block survived that.
Crank thrust bearings would be interesting to have a look at.
This poor thing had a really bad time wow 😬
Thanks for the video!
Now this is a video for me. I've had 3 VQ35/VQ37. I'm in the process of buying an 06 G to match my first an original I use to own.
Great tear down
Nice job tearing the engine apart Eric . Great video. Big Al.
“Paging Dr Blue, paging Dr Blue….. you’re needed at the fly wheel“
Finally a vq thank you
Never seen impact damage like this before, wow! Why is it, when you are ripping an engine for parts, the exhaust manifold bolts all come out? You are working on one you are keeping and the things snap off.
Very interesting teardown.
First off, congrats on the new addition to the family!! Secondly, there some counter pieces there or make a coffee table out of it. Almost wonder if a train hit it. Always love you vids and sense of humor to go with it!
great video. While I'm sorry not to see the carnage, I'm glad you get a good, sellable short block out of it. We're all better off when good parts are used again.
Cool teardown, hopefully that nissan NV has the VK56VD for the next tear down. I really want to see that engine opened up.
I'm thinking the driver woke up holding a bent harp and smoldering toga , Saint Peter stepped around his podium and pulled out a fire extinguisher for good measure
This part loon pretty good!
*chucks it at the wall*
Gets me every time.
I still want to see a Northstar V8
This engine reminds me of an ambulance the yard I work for bought a few years back, it had a low output version of a duramax with a 4L80E behind it. It bumped into something and bent the torque converter. (yes you read that correctly) The torque converter neck being bent bound it over the input shaft of the transmission, 2 or 3 of the original 6 torque converter bolts were still holding on (heads popped off the other bolts) to the stamped drive plate (which was bent like potato chip) but still bolted to the crank. This drive plate being separate from the cast flywheel on a duramax, which in this case was in pieces. Were it not for what you just read the transmission likely would've been ejected, and all that was required to separate the engine from the trans was cutting the steel drive plate with the torch around the converter bolts through the convenient user installed access gap between the engine and trans.
These videos are like searching for treasure!
That Pete guy, he's something else.
Only a few minutes in and it already feels special to me... I'm watching this sitting in the garage next to my HR roadster. It revved to 7,500 multiple times this weekend again. 65K miles. I feel weird watching this.
Alright I'm 38 in now I feel really good. It's a tank.
Stopping the crank for harmonic change. I use a trick my uncle showed me, i know not the best method. But remove plug and go to tdc on c1. 1/2 rotation on crank, feed about 6-8" of some 1/4" rope thru plug hole, clothes line works great. Intake valve will close, then continue spinning crank. The rope will stop piston without metal to metal contact. Turn back for removal.
Helps for changing valve seals without pulling heads too.
what worked on my 2014 Maxima was PB Blaster, jamming a 3/8 extension in the main pulley against the oil pan and using a long 1/2" breaker bar with pipe..
Love my HR these are incredible motors. I have abused mine/maintained it for over 5 years now. FBO tune 301whp 😁
watching you tear this engine up really makes me appreciate how much stronger Hondas motors are.
Great video, Eric! This was very interesting, I was surprised the block was as good as it was. Take care, catch YOU on the next one!
You did it, I asked for a VQ35 and you DELIVERED. You're special and I love you. And we patiently await the I DO RC CARS for the new youngin lol
The VQ engine family is legendary. Won awards for so many years straight. And is so buttery smooth. I had the variant below this one on my Altima. It was so much fun to drive. Plenty of power. Reliable engine.
One of the best engines in the game paired with one of the worst transmission unfortunately
@@KrymiaMusic couldn’t have said it better. Having had several altimas in my past I can say from experience I did not like the first version of the cvt. The revised version drove better but still wasn’t smooth. Now the non cvts where average at best. But I agree with you. Was never a fan of Nissan transmissions.
@@leosthrivwithautism the transmission problems started after the “reno merger” when the french came in. Before that, bullet proof and performance machines
@@KrymiaMusic heck didn’t know that much. Haha. But good to know. I guess it was why my older Nissans where way better than the newer ones I had. I had owned Nissans for over 8 years and just realized the quality progressively getting worse. But was never sure why. Guess this answers it. 👍🏼
Same story with our 2010 Altima SR. Engine ran great, CVT blew up at 125K, and it ate alternators and batteries about once a year.
You are absolutely AWESOME!
I have not ever tore down a modern engine, and I have never seen a water pump mounted inside the timing chain cover. It would be an expensive nightmare to change out the water pump on that engine, and a complete disaster just waiting to happen.
A square block of wood wedged into the block has always been my goto when dealing with a stuck crankpulley bolt. Never fails!
ooo yay. Is le new video. Definitely far later than you'd normally post, but that's fine by me. Since a video of good content is still a video worth watching whenever i get the chance :D
For a moment I thought we wouldn't get a chain guide thrown across the shop, also, nice water pump spike there.
"OMG, the dipstick!!". Love your vids, Eric.
Interesting tear down 👍.
love ur channel
Now I’m curious too see what the car looked like
Save the wiring someone might need the plug ends that aren't damaged.. like throtle body, coil and good side of varible timing. Car probably hit a pole as its very isolated spot of damage
This was a fun teardown. I'm guessing that the driver of that car had a pretty bad time from looking at the destruction from an impact..... on the driver's side, at high speed. If that engine came from DIY Pete, it likely took a WHOLE lots more abuse from his yelling at it before sending it to you. Minnie might have blessed it though ;-) Looking forward to your next one.
I’ve changed quite a few of these engines for rod knock and I’ve always thought they pop out far to easy for Nissan to not know they were going to have rod knock.the first one I did took 6 hours to replace the last one took 4 hours to replace
Looks like the aftermath of the typical oil gallery gasket failure these engines and the early VQ37VHR engines were prone to having...
Love tha videos keep tearing down engines
A lot of good parts to save, Coils, sensors, screws etc.
We use to have a full size, Ford E-350 van with a heavy duty trailer hitch. One day, she was rear ended by a kid driving his Father’s Acura Integra. He & his buddy were looking to the left at a For Sale car parked in a vacant lot. They didn’t notice that the traffic he was following by 20 car lengths had stopped for a pedestrian in a crosswalk. Just before impact he noticed the impending collision and jammed on the brakes. Which caused the nose of the Integra to dive, low enough that our van’s trailer hitch took the head off the Integra’s engine.
My point is that even minor collisions can destroy an engine depending on the details of the impact.
Incredible to imagine that big engine fits in a small sports car like the Nissan 350z!
I think we can all agree, donating a meme engine for you to tear down is going to have a pretty high level of expectation now.
Technique i got from an experienced retired mechanic to get a crank bolt off without an impact is to take the heads off or at just one and shove some rope in one of the cylinders and put the head back on and can take a breaker bar to the bolt and the engine wont turn all the over. Used it once and it worked great, and the rope is soft enough so it wont damage anything. time consuming taking the head off, on, and then back off but if that's all you got then it works great.
Another great tear down. Still hoping for a Northstar engine.
Nice teardown
Those exhaust manifolds look like literal headers! First time I have seen a 350z engine.
Whenever I replace a water pump these days for some reason I'm compelled to throw the old one on the ground
at 11:32 watching him try the breaker bar gave me flash backs to my g35... I had to tie inch thick steel cables to the frame to prevent the pulley from moving then used a 3 foot long breaker bar with a 3 foot pipe on the end of it and the power of two 18 year olds just to break it free
That powder on top of the intake is a dry chemical fire extinguisher, likely potassium powder. We called it PKP, (Purple Potassium Powder) in the Navy/Coast Guard on the ships. It's very effective on fires involving fuels and oils (Class B) .
Yeah if Pete is giving you an engine, it's gonna be fun one. I've seen some crazy mangled cars go thru his yard.
You know you're getting famous when people have a real effed up engine like this, and they think of you, lol...
Good luck with your new video machine. 😁
Edit: And props to Pete! 👍
Great video, really liked the sped up parts through the boring stuff, well done.
And “thats in really good condition” -SLINGS 😂😂
Yes, total destruction
Hope you got your editing stuff sorted for next week too 👍
I think you have a lot more Nissan fans than you think would love to see a yq37hr vid to compare these two. Maybe one that wasn’t driven by your average 350z owner
