    A great explanation and demonstration about VCM. Don't forget the age old problem of thermal difference on the deactivated cylinders. Something that plagued the Cady V8-6-4 and all others that attempt to switch off cylinders. You can't fool physics.
    The VCM on my 2019 Ridgeline was disabled very early on using more of a "smart" manipulation of the temperature feedback. Normal "pass through" at low and overtemp situations, but not allowing normal VCM temps to be reported. It also varies the output just enough to prevent a "flat line" record if anyone looks at the logs.
    My model version also has direct injection only which compounds the carbon situation by not having any valve washing.
    These engines have injector issues, carbon build up issues, motor mount issues, and now rod bearing issues (recall) which BTW are on the rear bank. The body is also prone to water leaks. IMHO Hondas are not the quality they once were.
    As the complexity of cars increases it seems the tech skill level is simultaneously (generally speaking) decreasing. This creates a real double-whammy problem for the consumer.
    Maybe I need something carbureted with points and a 4 speed? 😄

      Seriously
      Agreed. Been wishing occasionally that I still had a much simpler and yet way less fuel efficient vehicle… I really just want sh** that works and isn’t designed to fail, via EPA and other regulations by the government. They’ve had tech to make internal combustion engines way more efficient for DECADES and only recently instituted it when it’s no longer as fashionable or profitable to the oil and gasoline companies to not allow it to be used… and the powers that be know what’s they’re doing all the time.
      But they can’t drive us all the “unneeded” people into oblivion if they don’t take over EVERYTHING we need to survive and ruin it and make us (they think) completely dependent on them/ their governments.
      Makes me even more glad to know this world is not my home, by God’s grace through Christ alone!

    I've used a device called, "S-VCM Controller" every since I purchased my 2008 Accord v6 at 165k. It tricks the computer into not engaging the cylinder deactivation. I now have 260k and no oil burning issues at all. I'm not sure if the piston rings were replaced under recall by the previous 2 owners before me, but I've witnessed a v6 Honda Accord switching from ECO to normal mode while operating and a plume of smoke coming out the tail pipe every time. I did my research before purchasing this car & it paid off! I am not disappointed at all. During my 3 years & 100k with this car 0 major repairs. I'm glad I purchased the "S-VCM Controller.

    Very informative video and excellent tear down. We got a CPO 2015 TLX with 40k on it for my wife back in 2018. While doing my research, I disabled the VCM using S-VCM. Before installing the S-VCM I did get the annoying vibrations from VCM activation at certain highway speeds. The car now has 99k on it and it drives like a dream. Given I do my own oil changes when the oil life hits 30% (4,500-4,700k miles). Finally scheduled to get the connecting rod bearing recall done next weekend.

    Excellent video, in theory the combustion pressure is what helps to push the rings against the walls, so without that positive pressure the oil does get sucked past the rings into the combustion chamber. It wouldn't surprise me that that is the very thing that aligns the rings over time. A local engine rebuilder who builds the 5.3's with the AFM system states that the rings on the deactivation cylinders are always glued to the pistons.
    Its a horrible invention and it needs to be defeated on every vehicle that it comes with. Had I known about this system I would never had purchased my Honda, and I strongly recommend anyone considering a vehicle with cylinder shut-down to NOT purchase one.
    I'm not a fan of the original coolant temp VCM defeat method, unless it is the smart version. Even with this muzzler the VCM can still come on in higher temp weather. I would like to see a better method invented like a custom engine tune or custom PCM that could be purchased.

    VCM works at idle and light load cruising speeds for great gas mileage. I think the problem might be the use of low tension oil control rings, with a high mileage engine it may use a bit of oil to foul the plugs. The number problem is not changing the PCV valve before 50,000 miles if it goes bad it will suck in oil. I change my oil when it hits 20 % oil life.

    Is it possible to adapt VCM to non-interference engine with the intake & exhaust valves open during cylinder shut down? This case the inactive cylinders would not have compression and vacuum to cause the mentioned problems.

    • @Jon-yh3gb
      @Jon-yh3gb 3 ปีที่แล้ว

      Interference vs noninterference is unrelated. Leaving valves open would increase pumping losses. Basically half the engine would be engine braking and it would make vcm even less capable of improving emissions.
      It would probably be better to go with a super nonaggressive cam (targeting half power) for all 6 cylinders in eco mode and "vtech" back up to normal cam profile as needed. Should result in smoother power delivery and keeping even stresses and even heat throughout (metal expanding unevenly is bad) since it would still rely on their vtech style implementation it should be fine from a patent perspective. My guess is that vcm was one of those marketing based engineering decisions. Might be easier to explain "sometimes 6 cylinders" than "echo vtech"

      Leaving the intake and exhaust valves open would not really work on 99% of cars that have a shared intake plenum. The intake and exhaust would be directly linked all the time through the dead cylinder, bypassing the throttle and killing intake vacuum for all the cylinders still working. Maybe you could make it work on a car with individual throttle bodies and exhaust, but I doubt it.

I've been changing the oil with full synthetic high mileage every 3-5 thousand miles and the van had a rather big oil leak from the valve cover gasket. I put a 1/4th a bottle of AT-205 and that completely stopped the leak. After that I changed the sparkplugs after a Cyl. 2 Misfire code at 145k miles, I used some NGK Iridium plugs but I am noticing much worse gas mileage, would I have to disconnect the battery to let the computer relearn the new spark plugs? I dont think VCM is a huge issue in our case since my dad drives pretty fast, and the Eco light hardly ever goes on at 80mph. I think VCM only kicks in at 70mph and below

    It seems that fooling the computer into thinking the engine isn't warmed up would cause it to run open loop (as if the choke is on) which would cause it to run rich all the time (poor mileage, carbon build-up, poor cylinder lubrication). I also thought maybe one of the failure mechanisms might be when the back three cylinders are reactivated, re-engaging the pistons in the rocker arms might be a little dicey with the stationary rocker arm piston trying to engage a fast-moving part. But the oil-burning bit - ugh! Seems like it might be better to hold all the valves open, but then that would introduce other problems unless maybe there were separate intake and exhaust systems...

    Quick qualifier, I’m a Honda technician, while I agree that the VCM system isn’t perfect; I literally did piston rings on a 11 odyssey today, that discoloration difference between bank 1 and 2 is very common, and not due to a rebuild. Like literally virtually all 6 cyl Honda motors are gonna look night and day different between bank 1 & b2.
    Bank 1 is always 10x nicer looking then bank 2. I’ve asked 2 master techs I work with why that is, I’ve heard different theories, one is the path of the oil, the other is that bank 2 runs hotter because it’s always live (for the most part, cyl 4 can deactivate also)

      Original complaint was a b1 & b2 tw-wuc failure, turned out it was due to oil consumption fouling the cats. So it booked out at 27 hours according to Alldata , that’s 22.6 hours for 4 out of 6 piston ring sets then 4.4 hrs for both cats, we thru in a t-belt service that included water pump, belts etc concurrently to shave off 4 hours but still, it was pricey.
      It was about the biggest job you can do on that engine before it just becomes cheaper to find a used engine.
      Client was very cool, took me about 20 hrs to do the 27 hrs labor, that’s including valve adjustment (Honda’s don’t use hydraulic lifters) coolant flush, oil change etc.
      I wish I could post a pic of the four pistons I removed, cleaned and reinstalled with new rings. From the top, they looked like new (yes, I know you don’t have to go all OCD when cleaning the pistons but for 20+ hours labor, I’ll spend 1hr scrubbing pistons in a bath of VOCs :)
      As for the original question about discoloration, I’ve seen it all the way back to the first gen pilots and odyssey’s, so my theory is that the way the oil flows, it’s just hotter, more likely to leave deposits by the time it’s draining down the passages in b2, but again, that’s my guess, I have not had that confirmed by any Honda engineers.

I was hesitant to enable the feature, since I had control in turning it off, depending on what driving mode I selected. Since I’m only using flex fuel and the newer engines have both direct and port injection, I’m not too worried about carbon build up. Probably just have to keep an eye out for oil consumption, and ensure I change out the oil regularly.

      I have the svcm in my accord, works beautifully. From what I remember it only modifies the signal in the running temp range and passes the true signal through for any other temp and that seems to be my experience. And it's very easy to disable with the 12v power wire that feeds it. In power loss it becomes passive all the time and just passes the true signal through.
      I still need to do the rings and cats on my engine but the oil consumption has plummeted. From 5-7 qts between oil changes down to just 1-2 qts, which I attribute to the rings and the valve cover gasket leaking. Still need to clean the spark plugs at each oil change but it's better than needing to replace them all the time from a misfire.
      I'm a very happy customer.

    Why did they not let the exhaust valves open (leave them partly open), and use a separate exhaust perhaps? It would get rid of the issues.

      Or the intake for that matter. The valve rockers still ride the camshaft, and a minimal opening with the right timing will generate positive pressur in the cylinders.

      @@pizzablender I think they want to avoid vibrations and wasting energy on compression. But keeping the exaust valves partly open (during all four strokes) would do the trick.

      They keep the valves shut because the air acts like a spring. If the valves were open you'd lose energy moving air in and out of the cylinder. A spring stores potential energy when compressing the releases the energy when the piston goes back down.

      Ah, the wonders of modern technology, reminds me of the engines of the 80-90's emission control laden junkers. So much unnecessary extra parts. In the end its all about AFM coking the rings is what causes demise of AFM engines, first rings slowly coke up with carbon from unburnt/burnt oil in the cylinders, then rings freeze and the massive oil consumption begins. Leading to eventual rebuild all due to AFM systems. You cannot turn off lube to the deactivated cylinders or would score cylinders, a viscous circle for sure.
