I love my vq37 in my g37. I was able to do a 4000+ mile road trip across the US without a single hiccup and I daily drive tf out of it

10:52 You mention that this engine was only used in rear drive applications,but Infiniti had a AWD setup in the G37x model. Excellent video!

Wow this guy really knows this engine.

Great breakdown! One flaw with this engine is definitely the lack of an oil cooler. They have a tendency to overheat during hot temperature and motivated driving.

Still have PTSD from changing the gallery gaskets in my 350z VQ35HR but I love these motors...thanks for the breakdown. Definitely helped me understand how it all works.

let me tell ya man this is probably the best video i've ever seen on youtube. so in depth and well put together. you're extremely knowledgable thank you for sharing this about on of my favorite engines.

Great engine, very reliable. Most of the heat issues are as a result of the VVEL valvetrain, it generates alot of heat. These engines are specd for 5w30 oil. Its recommended to run a european spec oil for better thermal control. I have been running 0w40 Mobil 1 euro spec oil in my VQ37 Q50 since new and its never had any issues.

Very informative video! Thanks! The VQ30DE-K engines found in 2000-2001 Maxima and Infiniti I30’s are probably the last good engines from Nissan. No oil pressure issues, no oil burning, no drama, just good solid engines that are known to last well into the 300K mile range with just regular oil changes.

This is the best breakdown of this motor that I've seen. From how important the gallery gasket is. The water pump and timing chain. I like how you point out the impotence of maintaining the oil and temp on these engines. I love my 08 G37. They are power platforms. Truly. I just replaced everything on the front of my engine because added some mods and got tuned with uprev. I think my next investment thanks to you will be the Mishimoto oil cooler kit for around $600. If you know your engines weaknesses because they all have a few but, you can fix and improve them. Thanks to videos like this one. Thanks man!!

I have a 370Z and this engine played a huge part in my decision to buy the car. I can hold the motor at 6,500 RPM in 4th gear and it doesn't feel strained at all, just completely at ease and making peak power because of the excellent VVT system. If I did that in my Grand Prix I would probably boil the fluid in the torque converter inside of a minute lol.

Such an impressive video especially showing the VVEL in action at the end. Well done sir! 👍

I got mine with 275k miles and still runs great. Very reliable engine IMO.

14:50 “So Crusty” Adorable helper 🤣 Happy Father’s Day! P.S. very cool can design. Cam saves effort going the full 360 degrees! Wow! Happy they use metal cooling tube. Wish they would spend mor tech on their casting to make lighter. This engine could be made into a super engine with a few tweaks!

2014 Q60 with 170,000 on it. Mobile 1full synthetic since the first oil change using OEM filters. Amazing car, still breaks the tires lose punching it over cross walk paint through a yellow light!

Really appreciate the detailed explanation of the vvt/l system. Never understood the lift part until this video. Keep up the good work 👏

The amount of your knowledge about engines amazes me! 🤯

Great presentation - no distracting music, long buildup etc. A very detailed explanation in just over twenty minutes - great editing!

On the Hr and Vhr motors oil and coolant will not mix if there was a water pump leak, there is a weep hole that allows the coolant to drip down the side of the block and lets it leak down right above the oil pan on the driver side ive seen it many times lol i have changed water pumps on hr’s vhr’s quite a bit now and never seen oil and coolant mix

Nice educational video 🤓 Now when I look at my Q35DE, I’ll just dream of what could have been!! Thanks

Remember when an ex-girl I dated bought a brand new G37. It was good times with that car. Something’s I like about this engine (power & torque), & other things I didn’t like (wasn’t nearly as smooth as a Honda or Toyota V6).

Ive had a 370z since new for 11 years and I had no idea the head gaskets were metal. Those looked nice.

With some mods (Stillen dual intakes, Fast Intentions resonated high-flow cats, and a tune by Specialty Z) my 370Z is at 362hp. Also added a Setrab oil cooler since I live in Florida and drive it hard. Running Redline 5W-40. Best V6 ever.

I have one of these engines! The VVEL technology is amazing!

When I watched that video I thought it had something like 1M views or so. Where are all the views? Video is GOLD!

Subbed and liked- thanks for taking the time to share the knowledge you payed for in one form or another.. now I am not as ignorant and can intelligently keep up a bit better with the mechanics in my circle

Thank you for these videos. Your style is very clear and concise.

Awesome video. I knew the VQ engine was good but that intake cam is something else

The oscillating cam is mesmerizing :). Interesting engine, great video.

My 2019 370Z is hitting 42K miles and the engine uses no oil, as indicated on the dipstick, between my 3K mile oil changes. I have used the recommended Nissan ester oil since the beginning and change it every 3K miles. I did break the engine in very carefully and slowly, taking about 15K miles before it was fully broken in. Until that point, the engine used about 3 to 4 oz of oil during the 3K mile oil change interval. I don't use the OEM size filter that Nissan uses for this engine, instead using the filter from the VK56 engine. This filter is identical to the 370Z filter, except that it is about 50% taller. This increased filtration area results in about a 3 psi reduction in the oil pressure drop going through the filter, by my estimation of flow calculations. The particular filter I use is the Fram Ultra Synthetic, which supposedly filters about 98.6% of particles greater than 10 microns and about 99+% of particles greater than 20 microns. Abrasive dirt particles in the 10 to 20 micron(25.4 micron = 0.001") range are supposedly the most damaging to engine bearings and journal surfaces. When I cold start he engine I let the engine idle for about 5 minutes, until the coolant temp gets up to normal. After I drive away I keep the revs from exceeding 2K rpm until the oil temp hits 180⁰F. The engine runs quietly and smoothly, with practically no soot build up on the inside of the exhaust tips. At my 30K service trip I had one of the spark plugs pulled and dropped a borescope into the cylinder to inspect the piston top and the cylinder wall. The spark plug(iridium tip) was clean with hardly any electrode wear and the piston top had no deposits, other than a slight darkening of the original bright metal finish of the aluminum. The cylinder bore had no scratches nor scuffs and the crosshatch finish hone pattern was clearly visible. From my experience, this engine will run reliably for many years if given good maintenance and not abused.

Great in depth explanation and I always look forward to the tear downs. Keep up the great work..

let alone the knock sensor design flaw, the QR25DE (07-12 Sentra ser spec v) is a pretty good one too.... mine has 220 000 km. Still working fine even during our brutal winter seasons here in Quebec, Canada.

interested on seeing nissan’s VK series truck engines, I’ve heard they are based on the VQ but with two more cylinders, seen a lot of very high mileage Titans so they seem pretty durable as a workhorse

Wonderful video as I was trying to work out how the valves worked and how the actuator came into play. You have explained so very well.

love when you do vq engines , great content

I just screamed “finally!!!!”. Even though I am 7 days late 😭👍🏻

Nothing negative but one small suggestion when using the breaker car, make sure you apply force at exactly 90 degrees or perpendicular, as it does become harder when you try to turn the bar from an angle. It might or might not change whether or not you would be able to break the bolt loose, but you do lose or need to use more torque the farther you are from 90 degrees

I had no idea about this VVL system. Thanks for the video.

The way you undo the crank bolts from inside out gives me the heebies. Interesting teardowns tho

love it or hate it, the trumpet sound is cool

My 15’ Qx50 has this it’s amazing !

I have a 2010 G37X w 212k miles. Switched to 3k OCI with marvel mystery oil during the last 500. Runs very smooth. 0w-40 in winter 5w-40 in summer. Need to do the gallery gaskets soon owner before me never did them.

Still a hero thank you as always for this indept engine breakdown

I was trying to figure out why the vvl system was so complicated until you pointed out it was infinitely adjustable, then it clicked and I realized what a smart design it was. Side note, is a new set of bearings all this engine would need to run again?

So the reason why rod bearings are usually the first thing to go is because the crankshaft is spinning in the main journals it's not really subjected to any up or down linear force so whenever you run out of oil the rods are still getting pushed into the crank by the force of combustion which causes damage to the rod bearings faster than that of the main bearings

This guy explains better than some professors do.

14:50 so crusty! 😂😂 Love it when extras make it to the final cut of your videos!

Nice breakdown. Lots of metals, must be a very heavy engine. Replacing the water pump won't be quick either.

This is not a good engine....This is a GREAT engine!

Thanks for this awsome video. I wonder where you work to know that much about engines because this is not typical

I have a 07 G35 with the VQ35HR engine and it's a great engine if it's taken care of. I've recently did the updated oil gallery gaskets (original gaskets were not blown out) and water pump, mainly the water pump because it started to leak through the pisshole and looking at it and comparing it to my old Maxima DE engine, this one is a nice design with too much bulletproofing. I was looking at newer G37s but after seeing the VQ37VHR engine and the unnecessary complexity that was added to it, I quickly swayed away from it. Only 24HP and less than 10TQ gain over millions of dollars in research..

I have learned alot in one video your very informative.

VVEL is what valvetronic could never be

I’m curious and very nervous how the new 3.0L TT holds up. I have my doubts on it as an engine and I’m a little disappointed it’s smaller and relying on Twins but I’m sure it’s a blast to drive.

9:00 Nissan fixed the galley gasket problem but I forgot what year it was fixed.

Perfectly timed video. I'm debating between a Q70 and Lexus 4th gen GS350 and this vid will be super helpful!

I really hope that I can one day be as knowledgeable as you

Awesome class Professor, "so crusty"😂. my 2017 QX50 hasn't burned oil at all at 57k miles. Hoping it stays that way cause I love this engine. 1st noteworthy repair just a cracked mount.

Very good engine teardown bud because I just actually subscribed to your channel on KZfaq Channel bud because I have always loved your videos bud keep them coming bud

So cool to learn more about the engine in my car. I have a Y51

Oh yeah called that spun bearing. Was looking forward to this teardown excellent work as always sir! Can’t say I’ve seen such a close look at the VVEL system before I learned a lot.

You lost me at "now we're going to start at the top here where the valve cover already came lose" at 1:06. Amazing.

Very educating breakdown as always. Nice work

This guy knows what he's talking about

I have one with 180k miles, no leaks, no oil consumption .I always use good fully synthetic oil and add 6 quarts instead of 5.

You can make an incredibly strong engine…but one drawback: it must have oil!! 😂😂😂

Excellent breakdown bro, keep it coming are you going to do a rebuild on this at some point? Like a detailed step by steph if we want to flow part 1 through 10 let’s say? Asking for a friend… lol

I really enjoy your videos. Thank you.

I have this engine in a '17 qx50....and Id like to keep it running as long as possible. I am currently running spec oil and bg MOA. Is that good or bad? Ive read in the comments 0w40 euro spec is the better option. a lil bit of guidance would be greatly appreciated. AWESOME VIDEO btw...THANK YOU!

Great video. Did not know Nissan used VVL.

I would never comply again about the Chevy small V-6 tear down process. This engine is a nightmare.

I dint know that engine nissan had that crazy tech on these V6s engines,that was a spot on breakdown and elaboration you did bro,i salute you! Now if you can find its competitor engine from toyota,the 2GR-fse,i could love to know how toyotas’ beat it,granted realibilty aside first!

18:12 Nissan genius

The VR30DDTT seems like a great engine as well in the new Z and the Q50.

I love how he kept saying how strong it was, then just casually mentions they’re notorious for burning oil 💀

Newer 4.0 VQs pretty good besides the timing chain driven water pump

Thanks for your good detail 🙏👍👏

Can't say I like what I have seen about this engine...

E-Torx, ran into those bolts on a MR18DE I needed the torque converter from (engine seized). Wasn't anything a 13mm and a hammer couldn't handle

Pretty sure the 370Z nismo made 350hp with the VHR but that might also be due with a higher flowing exhaust

it be cool you could do another engine teardown on a Nissan GA16i 4 cylinder found on older Nissan Sentra and pulsars from the late 1980s and 1990.

Do the VQ35HR now

I enjoyed this too much 😁

I always thought Nissan was going to continue improving this type of variable valve lift and timing, but it just kind of died off

phenomenal! thats a job well done

The VQ37VHR is the poor man's VR38DETT once you boost it.

Thank you for a great lesson . Man you are a genius . Well im going to look at a 2016 qx70 with 156k mile for $8,900 . What do you think .thank you

This is brilliant. Thank you so much 👍

People still go to college to learn this stuff 😮... Man I feel like I owe you some tuition

I love this video help me a lot man!!!

Awesome video!!!

u genius ..subscribed! keep up the good work !

Great video! I wouldn’t say the last good motor, the vr series are very good and very strong. Most new infinitys hsve the vr30det which is fantastic

Another nice video 😄 looking forward to your videos! Would it be possible to disassemble another famous Volvo engine? Like the 2.0 or a six cilinder?

100 hp/liter engine rated at the crank. Easily revs to 8,000rpm.

*One fatal common flaw of this engine are those cardboard gallery gaskets. You done effed up nissan. If you own a 13' not to worry, since nissan replaced that cardboard with metal gaskets as it should have been from the start*

Great video as always. You wouldn't be able to find a RB series of Nissan engine to teardown would you? For an old skyline fan. Cheers lol

Dude when are you doing a Northstar engine? You will have no problem finding dozens in junk yards

VQ37 isn't known for burning oil AFAIK. Lack of oil cooler is a bit of a PITA

I bought my 370z back in 2015 with 23k miles on it

😭when you throw the cam onto the cam cap cradle
