The Last Good Nissan Engine: VQ37VHR

[@SemperMortem]

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

[@LA_nomad.est.XX91]

Every vehicle being sold in the USA for probably the past 30 years being daily driven can still make a 4,000 road trip ??? LOL being moreso sarcastic but this does confirm my personal opinion that despite owning one and actually still liking it VQ35DE ENGINES are not long term reliable AT ALL, are way overpriced used and new parts are extremely inflated , ALONG WITH ONCE HITING THE 500 HP MARK THEY LACK PRACTICALLY 100 lb ft of TORQUE vs HORSEPOWER and by 700 HORSEPOWER their TORQUE IS OVER ....YES... FREAK'N OVER 150 LB FT BEHIND making them extremely rare and odd in a BAD WAY ... still like em but they KINDA FUCKING SUCK BRO... (S)

@@LA_nomad.est.XX914,000 miles is a long ways when you consider the age/ mileage of the vehicle. It’s exciting when you must have faith in a vehicle to get you where you are going when you are practically driving across the entire North America. It’s exciting once the car finishes the job and delivers despite what other people may have thought, I’ve been there a few times. In my experience, I use to buy G35’s at auction, I use to buy & and sell, drive, many different cars. The Infiniti’s were higher mileage & they were all reliable. I drove an 08 G35X sedan for a while & it was pleasurable. Never had an issue with the car, it had 185k miles on it when I got it for 5k or so, it was a nice car & ran strong, shifted just as aggressive as it’s supposed to, the awd still launched it to 60 in about 5 seconds. It ended up being a good buy, that car.

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.

[@EC-ol8nz]

Very neat engine, with an oil cooler very cool!

I find that interesting since the older G35 had oil coolers. It probably would bolt on the oil filter housing if you wanted to add one anyway.

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.

[@speedkar99]

At least the 350 is longitudinally mounted and you can get space up front. Can't imagine doing that in a FWD transverse mounted engine!

[@matthewg.4223]

Is there anything preventative we could do to avoid the gallery gasket issue at all?

[@mikeulickey3911]

I installed an oil pressure gauge on my 370, so if pressure is lost you have a much quicker way of knowing. Otherwise replacing the gallery gaskets themselves with stronger ones and better hardware is the best way, albeit expensive in labor.

[@mattschlatter4999]

I think Nissan changed their galley gaskets to a steel reinforced design in 2015 I believe? Before that they were all a multi-layered paper gasket or something like that. The gaskets themselves usually held up, but with the high pressure oil running through the galleys, the bolts would tend to back off and then the paper gaskets would blow out without the clamping force of the bolts anymore, which would lead to low oil pressure especially at idle. I've changed the galley gaskets in my Frontier and 350Z with EPS Tuning gaskets (they call them gallery gaskets) and they seem much better designed with great instructions on how to put them on so they shouldn't ever fail or have the hardware back out on you

[@ILoveYahuah316]

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!!

[@speedkar99]

You are welcome. While the engine produces good power, the FM platform is a heavy one that doesn't handle very nimble...mor eof a luxury touring than sport.

[@SantanKGhey1234]

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.

[@winebartender6653]

Run the same oil in my g37 as well. There is a noticeable difference in valve tick noise between this and 5w30, with the 0w40 being much quieter to non-existent. I will say, the slightly heavier 40 (granted, the Mobil euro 0w40 runs much closed to a 30 weight) causes a bit more engine drag after ~1000 miles than the 30 weight does after the same mileage.

[@BMC530i]

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.

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

[@videomaniac108]

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.

[@Pawelmps]

Good job mate, it should last for a long time, I do the same with my BMW N55 engine now at 81000 km no oil leaks or oil burning

[@winebartender6653]

You really shouldn't let the engine idle from cold for that long. You aren't doing it any favors extending the warmup of the oil. Ideally, you should be turning it on, waiting for the idle revs to reach ~1000-1100 rpms/when the initial cold start procedure is finished (when the exhaust quiets down after purposefully running rich), and then begin to drive, staying under 3k rpms until operating temp is reach. It's a horrible myth that letting your car idle until fully warm up is a good idea.

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

Personally noticed it is highly dependent on what oil is used. Newer Pennzoil 5w30 seems to burn/blow-by quite a lot (the VQ isn't alone in this) whereas Mobil 0w40 doesn't have the same issue, from my experience.

[@D.Bondar]

​@@winebartender6653пытаюсь подобрать масло, motul 5w40 не расходовало, но на нем шумно работал двигатель. mobil 1 esp 5w30 был расход около 100-200мл за 7000км. Как раз думаю попробовать mobil 1 fs 0w40

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.

Yep since 2008 G37

So when in their what should be replaced if over 100k? Oil gallie gaskets, water pump, thermostat, timing chain anything else you would suggest to replace? Like tensioners?

Is there a coolant drain plug on the engine block when flushing the coolant? Thanks

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

Got an off-topic question for you. Would you have an opinion on what is the preferred gasoline for the 3.0L V6 1MZ-FE? My 2000 Camry manufacturer's manual says: "1MZ−FE engine: Unleaded gasoline, Octane Rating 87 (Research Octane Number 91) or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91(Research Octane Number 96) or higher is recommended." Would you suggest "premium unleaded", especially for shorter, city-street commutes? I want to use Chevron's Supreme Plus with Techron. Thanks speedkar99.

[@speedkar99]

87 works fine with the 1MZ. Using 91 isn't going to make it faster or last longer. You'll get better fuel economy but not enough to justify the difference in fuel price.

[@snoofayy6150]

i remember reading a Solara forum post where one guy was talking about how the knock sensors were overly sensitive on the 1MZs and as a result almost 90% of the time they were running on very very retarded timing, he did a little practical experiment where he filled his solara with 94 octane and threw in off the shelf some octane booster and a fee miles of driving later the car woke up and had GOBS of response and power

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

Have you seen my Q50 review? It's very complex and tight in the engine bay. And for no power gains over the VQ37...

[@BigHeadClan]

It’s a fantastic motor has some teething issues with turbo seals that need to be sorted out but yeah engine bay is very tight. Lol

[@BigHeadClan]

@@speedkar99 it actually makes about 30 more wheel horse power and 50ft lbs more torque even in the 300hp trim. The 400hp version is closer to 100ho and torque over the old VQ37. Nissan just downplayed the numbers on the new motor. It’s more complex but that’s typical of modern engines and they don’t overdue but is very cramped engine bay no question. XD

[@infinitibossauto]

@@BigHeadClan turbo duh! Dont u av sense ? slap a turbo on vq an even a safe tune easily an deliberate makes more power than 3.0 tt

[@BigHeadClan]

@@infinitibossauto You can’t just slap a turbo on an engine that wasn’t designed for it from the factory and achieve good reliability, the fuel system, durability and supporting components all need to be changed which isn’t cheap. The VQ platform is also nearly 30 years old and needed to be replaced from both a technology stand point and emissions stand points. They took what they learned with the vq37 and Vr38 and mass produced a capable twin turbo engine.

[@zzzfffccc]

Not sure if anyone added in the comments yet, but the failed oil gasket around the spark plugs is a common problem based on what I seen from other owners, including myself.
