The Nissan VQ series of V6 engines, which originally dates back to 1994 to replace the VG series of V6 engines, has been a stronghold in Nissan and Infiniti's offerings over the past two decades. Its most popular version is the VQ35DE, which were fitted many vehicles in the early 2000's including the Nissan Altima, Maxima, Murano, Pathfinder and Quest; and the Infiniti G35, M35 and FX35, and is still used in production vehicles today.
In this video we take an indepth look at a VQ35DE sample from a 2006 Nissan Murano, tear it down to see what's inside and how it works. We will also look at what makes this engine such a strong contender for Nissan, being fairly reliable and versatile across its product lineup. Additionally, we look at why these engines do fail, and examine common failure modes discovered over the years.
Nissan has definitely created an award winning engine that was way ahead of its time almost 20 years ago when it debuted. Sadly, V6 engines in its lineup are slowly being replaced by turbo 4 cylinders, but the VQ series will still be sought after for years to come.

Synthetic oil. Keep the oil level topped off and change every 5,000 miles. Along with regular maintenance to prevent overheating and these engines will last 200,000 miles plus. I just replaced an alternator on a 2002 Maxima, with 196,000 miles on the engine.

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.

Speedkar99, This is a great overview. I have had to change the valve cover once on my 2002 Maxima to resolve one of the oil issues that you have pointed out. As you pointed out I also had the oil leaking into the spark plug socket but that was resolved after the valve cover was replaced. After 16 years of ownership the car is still solid and feels like new. My car is a manual and it really is still a joy to drive.

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 had to replace the chains and guides on my Quest. The tell tale rattle on start up that goes away after warm up really gives it away. I was told the engine needs to come out but it DOES NOT.

Fun fact about the oil galley gasket job on the secondary timing cover....when I worked for Nissan, you couldn’t buy just the gasket....you had to buy the whole timing cover.

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.

The early vq35 did burn a bit of oil but it wasnt a huge issue until late in life and easily addressed with good oil and exhaust mod. Think my 02 altima only took 1/5 a liter every 2 months at around 200, 000km.

Internal water pumps are unfortunately quite common these days. Audi, Chrysler and Ford all use them to name a few. Probably one of the most common engines in North America (the Ford 3.5 Ecoboost V6) uses an internal water pump

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.

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.

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.

Agreed. The cdoo9 6 speed manual is actually used in the Toyota Supra also mated up to the 2JZ. It can handle basically anything you thro at it. You can tell that Nissan and Toyota collaborated in putting that transmission in race ready cars. The 94 Supra is obviously a much better fit than the 03 g35, but still a good choice.
