Good explanation of this engine. The biggest issue on them is the plastic guide on the tensioner. The top of the arm snaps off and allows the plastic guide to slide down off the tensioner.

I did it myself.

I had a 2004 Infiniti G35 6MT with the VQ35DE motor. I put 169K HARD miles on that car and the only issue I ever had with it was the camshaft position sensor failed.

Oh wow, awesome video! I had a 2003 Nissan Pathfinder with this engine. We bought it used as a lease return with 80,000km’s. In 2006. Just traded it in with 300,000km’s for a new Tacoma. The engine and transmission were still going strong. I did regular maintenance with oil changes every 5,000kms. IF I floored it, it would still get up and go. Burned about 1 litre of oil between oil changes. Not bad for a vehicle with that many Km’s. Also, drove it hard through the coastal mountains 8-9 times every year during the summer. Only had one real issue with it and that was the throttle body failing at 120,000kms. Cost me 1k to fix. Other than that just regular maintenance. Came with the 4spd Auto. Auto trans fluid was changed just once from the dealership at 120,000ks. No problems with it. Must have been the trans cooler it came with.

[@cleric670]

Preface: Good video, always like your stuff. Gotta clear up a few misconceptions about the VQ35DE though. The oil doesn't mix with the coolant when the water pump fails, there is a little hole drilled in the side of the block just outside the pump, that's the traditional "weep hole". All DE motors have it both the RWD and transverse. Also the front galley gaskets inside the timing chain cover never had an issue leakingon the VQ35DE as you mentioned. That problem was almost exclusively on the VQ35HR motor which is a COMPLETELY different motor with basically zero interchangeable parts to the DE. Just to clarify, the HR is not just a beefed up version of the VQ35DE, it's an entire ground up rewrite of the ENTIRE platform with zero interchangeable parts, it has more in common with the newest VQ35VHR. "VQ" just means "variable cam timing, dual overhead cams, electronic port fuel injection". Hence why three generations of engines all start with VQ. The biggest issue with the valve covers is not warpage which I've literally never even heard of. The problem is the spark plug well tube seals are built into the valve cover and not individually replaceable. When they fail it typically involves getting entirely new valve covers. There is a way to drill out the existing and replace with ones that sort of fit but it's quite a pain. The buildup on the pistons is almost ALWAYS caused by the poor quality piston rings used in the DE, the cause excess blowby gas to the crankcase which increases oil vapor consumption through the PCV system, in addition to just sucking it off the walls of the cylinder, these engines do have oil squirters so there's plenty of oil to suck... Typically the lower plenum (which you had already removed from the engine, the part with the injectors is actually the intake manifold) will have a massive amount of oil in the center galley section.

[@larryvercher9809]

When the water pump fails the coolant does get into the oil pan. It did on my 02 Maxima se. No fun replacing water pump.

Anti freeze every 100,000km and other fluids as needed. I still haven't flushed the cvt fluid, but I may have that done soon. I'm not having issues, its just well beyond the recommended cvt flush, interval. I bought the car, years ago, for $3900 canadian, at a dealer, and it had 121,000 km on it and was mint.

My car most likely has failed timing chain tensioner, looking to tear it down to see if it skipped too much and this video is the best teardown video I found!

[@nowimhigh]

The oil builds up on the top of the pistons and valves thanks to emissions. The pcv positive crankcase ventilation valve is vacuumed back to the lower plenum and on the driver side valve cover the extra pressure is ventilated into the intake tube. It also allows fresh air into the crankcase. I just installed an oil catch can and I have both banks running to a baffled set up. It's a closed system so it ventilates back to the lower plenum vacuum. It collects about an ounce of vapors, oil, blow by, etc month. I checked my plenum and it's clean as a whistle. Before when I installed my plenum spacer it wasn't too bad. But it did have oil residue throughout the plenum going down the intake manifold and into the intake valves. A made sure to run a can of seafoam through the brake booster vacuum into the plenum. Then while I did a tune up and changed the sparkplugs I squirted some sea foam down the spark plug hole onto the pistons. I moved the crank to move the pistons a bit. Squirted a little more sea foam and let it sit over night. I then cranked it up and it burned all of that carbon off the pistons and valves. It made a world of a difference and the OCC does do its job. I just got a cheap $20 one off ebay it has two inlets for both banks with a baffled filter set up. Then an outlet that you can either vent to atmosphere or run as a closed system running back to the plenum. I highly recommend doing this if you just purchased a higher mileage G35. Your engine will run so much smoother and stronger.

The VQ30DE was the main reason I loved my 1995 Nissan Maxima. It pulled hard to 4,000, then felt like it suddenly got even more powerful and kept pulling. What a great sound!

When you make a great enigine, there is much to improve over the years. The Mitsubishi Sirius 4Gxx series lasted 37 years.

[@nbowling10trio]

Most manufacturers copied the VQ design and made their own version of it. It’s that good!

[@volodymyrbuchak1852]

About the waterpump. You’re wrong there,buddy. This design has separate seals on oil and coolant systems with outside drain betwin. If any system leaks,they’ll never mix together,but will drain outside tru the drain passage. Werry good design,despite it’s Nissan. On my Xterra it takes around 30 min to change the waterpump,but the engine positioned longside,on front wheel drive maybe a pain in rear end (engine positioned sideway)

At least you got the VQ. Hopefully the CVT lasts

[@darthganu]

@@speedkar99 In regards to my Quest, my mechanic just scanned the van a couple of weeks ago and said the CVT is in excellent condition.

[@exit5398]

Great info in this, extremely accurate, minus one small portion on your final thoughts. You said that the transmissions that Nissan chose to mate with the VQ were all poor, but that statement only applies to the automatic transmissions, which were utter garbage. The manual transmission option from 2005+ was the CD009, and is touted as one of the best available 6 speed manual transmissions in the tuner world. There have even been a few drag race 350z's pushing 1000 bhp+ on stock transmission internals and a really beefy clutch without damaging the driveline.

[@jimmyerbe768]

So far knock on wood that my pathfinder with the 4.0 engine has not had a transmission problem it is a 2006 and I have about 300,000 miles on the transmission I am on my second engine and I pull a boat on a trailer quite a bit on long distances, My transmission has held up well I replaced the radiator as some had antifreeze. Enter the tranny fluid from a leek inside the radiator also added a oil cooler for the the long haul dragging the boat.

Awesome, entertaining video. Your delivery and editing are brilliant whether it's intentional or not. There's always someone's old shirt to do the cleanup with which I find hilarious. So I do want to mention one thing, as someone who owns an Xterra (VQ40DE, just a bigger-bore version of the 3.5) and has been through nearly every possible situation from harness to head gasket to "how the hell did a nut get into my combustion chamber"... You mentioned that it's "mandatory" to remove the rear timing cover when doing head work, when in fact it's not required at all. The short 10mm bolts that sit behind the timing sprockets are all that you need to remove. Some go into the cam bracket, some go directly into the head, but it's evident when one gets that far as to which ones must be pulled. That's it! Save yourself a couple of hours.

the CVT is not the worst CVT ever made. hindered by it yes but ive seen and felt worse. owned both an auto and manual z.

[@ShaneRimmerWorld]

I had one of those in a 2006 Altima 3.5 SE. I really liked it until it ate the timing chain guides at 110,000 miles. You aren't kidding about the clearance on the front side of that engine. Of course, even changing spark plugs required removing the upper intake plenum, the strut brace, and the windshield cowl. Interestingly enough, in my application, the oil filter was remotely located in the front passenger wheel well and there were two accessory belts where one of them had a manual adjuster.

Glorious engine. I ran this thing hard in a G35 for 15 years. It was modified. No naturally aspirated V6 ever beat me. I ran down v8 engines who were surprised how fast it was. The thought i had a turbo. If you modify it correctly with the right parts and change your oil using Royal Purple, this car performs like a little v8.

[@papilgee4evaeva]

As the owner of an M35, this is satisfying to watch. One thing about the valve covers is that the spark plug seals are not directly replaceable once they fail... and they are very well known for failing.

[@papilgee4evaeva]

@SG2 February From what I understand, the standard remedy is to replace the entire valve cover (though a few people have found alternative fixes, but those seem to take as much time as replacing the cover itself). I have a replacement valve cover sitting in my garage waiting to be installed. Just haven't had the time. 😄 Mine is on the driver's side also (I think that's the most common failure side). No other leaks have shown themselves, just the oil into the spark plug tubes.

We've had 4 VQ40s, still have 2 at the moment, the other ones would still be with us if the vehicles that carried them hadn't each eaten a massive T-bone. One was over 400 with nothing but oil changes. 1 07 X auto, 2 14 X P4X manuals, 1 14 Frontier auto base 4wd. We lost 2 Xs to getting T-boned, walked away without a scratch and both ran and drove, too much body damage and frame tweaked. One was a dump truck towards rear passenger flying over a hill, no brake light in footage. The other was a junkie sleeping through a country stop sign into my driver side when I was going 50 on a two laner.

Hey, I own a 1996 infiniti i30 with a VQ30DE engine, and I would love to learn more about these engines, what are some good upgrades, etc. .... Thank you!

[@JoeUrbanYYC]

As someone who replaced my leaking water pump this spring on a VQ30DE seeing those access covers for the tensioner and pump gave me flashbacks to hours of frustration. Imagine trying to access those tiny bolts with only an inch or two clearance in front, doing it mostly by feel, and hope you don't drop one down into the timing chain cover, especially when unbolting the pump! That said I'm impressed with the engine, I drove a week, probably 5 hours of driving on a milkshake mix of oil and coolant due to the pump leak that was probably 2l over the recommended capacity of oil alone and the engine is still ticking away smoothly with almost 300k km on it.

Oh and having to remove the tensioner without the piston and spring also shooting down into the timing chain cover. A very stressful repair!
