WELL WELL WELL! We have a very special engine on the stand today. After a hard search, I have finally found one of them variable compression turbo engines from Nissan. This is a KR15DDT 1.5L Turbocharged 3-cylinder with variable compression from a 2021 Nissan Rogue. I do NOT know mileage but from the looks of it, its not a super high mileage engine, as its only a few years old at the most. This teardown was pretty crazy. The top of the engine is fairly normal, but the bottom end is an engineering marvel! I really was impressed by the implementation of this technology however....adding all of these moving parts to cars that aren't that well taken care of is a recipe for future disaster. Is this failure going to be a common occurrence in the future? Should you avoid buying a vehicle with one of these engines? I'll let you make that call.
Why am I doing this? My name is Eric and I own and run Importapart, a full service auto recycling yard. Part of our model includes buying core and blown engines, dismantling them and selling the good parts. We do not rebuild engines, we merely sell parts to those who do.
I really hope you enjoyed this teardown. As always I love all of the comments, feedback and even the criticism! Catch you on the next one!
-Eric

On the positive side, Nissan has improved the perceived durability of their CVT's by designing an engine that will fail before the transmission. 😔

I'm a rental fleet mechanic and back in '21 we had a rogue with less than 1k miles developed a bad misfire so we sent it to the dealer. The tech there said he found a smashed spark plug so they consulted Nissan and they had him replace them all and shipped it. That fix confused me but I put it back out on rent. Less than 1k miles later it was back for an engine knock and the dealer replaced the engine. I believe we had 2 more make a mess of the bed and they got new engines also that year. It's cool to see how it works (or is supposed to work) and confuses me even more why replacing the plugs was supposed to be a fix. Glad you got one to tear down and now I hope I never have to get into the guts of one.

@CaptainSpadaro Ай бұрын

I was wondering if you'd even be able to FIND one of these. Reason I say that is because I used to work at a Nissan dealer and I was told that we (Nissan dealers) were replacing these left and right. One of the master techs showed me a thrust bearing from an engine he had partially torn down to diagnose; somehow the thrust bearing walked out the front crank seal (his words; I never saw the engine it came out of so I cannot disprove what he said). I was also told by one of Nissan's trainers that these engines were originally built in Japan, with no issues, then production switched to Decherd, Tennessee, and that's when the problems apparently started, which makes me think it was a local supplier issue; any Rogue currently on dealer lots will have an engine out of Japan, though I'm not entirely sure when the change occurred. I had also speculated that the failures they were seeing might be because people were running the engines too far on the break-in oil (the so-called 'Oil Control System' will let the car go nearly 10k miles before it says to change the oil; I programmed the manual reminder for 3k or 5k on EVERY Rogue I did a PDI on); the aforementioned master tech did say that all of the bad engines he had seen hadn't even had their first oil change yet, so there might've been something to it. I can't tell you the number of Rogues I put 5W-30 in, even though this engine calls for 0W-20 and 0W-20 ONLY (the writers at the dealer I was at never put their feet down and explained to customers that this engine wasn't one of the Nissan engines where you could run 5W-30 in it); I wonder if that might've had something to do with it; I also couldn't tell you the number of Rogues I saw without the manual oil change reminder programmed. I personally would not take a Rogue with this engine much past 5k miles on an oil change because of the overall complexity of this design. This engine and its brother, the KR20DDET, are under investigation by the ODI for failures, and the master tech I was talking to said he had heard whispers of a stop-sale, but that hasn't happened as yet. I will also say that when you start a Rogue with this engine, it sounds very odd, like it doesn't want to turn over. I don't know if that's normal 3-banger acoustics or if it's related to the variable compression mechanism. Both engines don't feel as unique as you'd think to drive, either (part of me would like to see how a KR20 does when mated to a fixed ratio auto, or a manual). I also saw a few of these with the exhaust VVT solenoid(s) leaking; never got an explanation as to why. 1:32 the VC-Turbo engines didn't come online until the 2019 model year for this market.

@propertyrights907 Ай бұрын

I did not work at the Decherd engine plant, but I did work at the Smyrna, TN production plant for a few years before moving out-of-state for a career change; & I would never personally buy nor drive a Nissan. The amount of acceptable errors on the production line is a little sickening, and the line supervisors are all fine with it because the corporate culture in the factory is just so highly competitive and cost/time-oriented that it looks better for them to send errors out of their production zone than to flag a unit for a mistake. I could only imagine the pain and trouble Nissan dealer service techs have to go through every time they have to remove the dozens of underbody plastic trim screws on a Rogue or Leaf just to find a cross-threaded subframe bolt. It's probably not even a Nissan thing, I'd bet the US OEM cars still built in the USA suffer from the same lack of work ethic and care for the consumer. Nissans are just low quality vehicles nowadays, I wouldn't invest my money or safety in them.

@edrannou3914 Another tip is to dip your socket in some water. Then dip socket in some beach sand. The water is only used to help the sand cling to the socket. Push in hard on the socket as your attempt to remove bolt cuz you don't want it to try to torque out any amount. Depending where you're working, obviously you don't want sand residue falling just anywhere so a bunched up oil soaked rag underneath can help collect residue. This trick can work on Allen head, torx, even normal screwdriver tips. 👍

The funny part for me is, all the complexity and added failure vectors it introduces don't really give you that much back in return even compared to modern offerings in a comparable price point. 181hp is a lot...but not really. 25mpg is a lot...but not really. I may be the fuddy-duddy in the bunch, but if I've got that much gadgetry waiting to go bad at any second, I either want 450+ horsepower, or 50+ mpg to pay me back while I wait for the big clunk. Rule #1 for me is simple; if there are added failure vectors, they must be countered by enough benefits to outweigh their risk. This gadget reminds me a lot of the 8-6-4 Caddy engines; a novelty that will be looked upon long-term more as a pain in the ass than as an actual benefit.

@evertonptube Ай бұрын

Your point makes sense, but if a fairly new engine was quickly starved of oil (no evidence of why in this case), that would explain the damage. The only thing I could think of is the engine being under-filled with oil at the factory, or the oil pickup being too high (which I doubt such a major thing would get overlooked). Either way I've wanted to see this technology used for years, and although I'm happy it made into production, I'm very sad to see how poorly it got executed from the other comments on how often this happens.

It is, 225ftlbs from 2,800rpm and up, and that's on 87 octane, and while getting 37mpg on a big SUV on the highway. My old 4.0 liter V6 in my Jeep took more RPMs, made way less power, and was way less efficient. Even by modern standards, if we compare it to the virtually identical size/weight Equinox, the Chevy 1.5T makes 35hp less, 41ftlbs less, and 5mpg less.

@BoopSnoot Ай бұрын

I think its by design. All the consumer cares about is that it makes 225ftlbs of toque on 87 octane while getting 37mpg on the highway in a big SUV, which is quite amazing. They also managed to eliminate turbo lag, which is also surprising considering how big the turbo is, and because its a muffled (from the turbo) 3-cylinder it actually sounds more like a V6 when you floor it. They even put fake shift points on the CVT to trick people into thinking its a traditional automatic. So most people will just think it has a V6 under the hood with a regular transmission, which isn't a bad thing to feel.
