Yeah. You and everyone else. That’s why Toyota and GM and lots of other manufacturers went to chains. However, it turns out that chains can stretch and jump a tooth from overheating if you are dealing with oil dilution and comsumption combined with excessive oil change intervals in modern direct injection engines. And since they aren’t a scheduled maintenance item-expected to last the life of the engine-they aren’t regularly checked nor are they easy to replace. If you’re lucky you’ll get a check engine light with a code for cam position. If not, the results are even more catastrophic than a timing belt failure because you’ll likely damage all of your pulleys and a metal rather than plastic timing cover sending all kinds of metal cornflakes to the oil pan. Gear driven is good.. but would be very complex for DOHC engines.. requiring worm or beveled gears combined with drive shafts (this was used on the RR Merlin for SOHC) rather than stacks of idler gears for each cylinder bank. The last automotive engines I know with gear driven cams are the Pontiac 2.5 Iron Duke and the Ford 300 inline six. Both straight engines with overhead valves that only needed two gears. A vee engine would need an idler because the camshaft needs to rotate the same way as the crankshaft for simplicity.

1:25 I have a theory on why one bank is coated darker in oil than the other. The side that is darker is where the pcv valve is located (which would also mean that dark bank of the engine is bank #2). I think it’s darker due to the location of the pcv valve and it’s functioning causing a byproduct of its work by making the whole valvetrain darker on bank #2. This is my theory.

Honda first used that engagement pin system on a domestic market motorcycle that had four valves per cylinder, but could selectively activate two of the four valves, or let them remain closed. Once it proved reliable, it evolved into VTEC, giving a phase change in timing, lift and duration instead of just valve area and swirl.

Great video, speedkar99 At 10:31 and 10:45, you don't see any movement because the solenoid valve is pilot-operated. This means that it takes a bit of the fluid which it is controlling and channels it towards the clicking solenoid (the pilot), which then uses this fluid to activate/operate the plunger. So without oil, you will only hear clicks but see no plunger movement. In other words, the VTEC solenoid actually needs oil to first operate itself before it can operate the camshafts.
@daviderhahon

And that's why you shouldn't wait for your oil to get so very dirty before replacing it. Dirt can easily block the small channels in the solenoid valve and render it useless.

If you can get a VCM J series engine to tear down you may be able to find evidence of VCM carbon build up that caused Honda to issue an extended warranty on ring replacement for affected engines. Engines that are afflicted produce misfires on the affected cylinders because the spark plug is full of carbon and they start burning oil because the rings become coked up. It does seem that a ring replacement fixes the problem, but it's an expensive job if done outside of warranty.

I think whether it turns into a problem or not has to do with multiple factors, e.g. fraction of time VCM is active (dependent on driving conditions and style), quality of oil, quality of gasoline, etc.

Are there any sensors for that so the engine would know that they stayed locked? Also, does anybody know why one half of the engine is more dirty ?

Great channel and content. Keep up the great work! The back side of the J-series engine is cleaner because of the VCM system (Variable Cylinder Management). There are different implementations, but it will shut down the rear bank of cylinders to reduce fuel consumption under ECO mode. The engine basically runs on the front three cylinders under light steady load. Later implementations could deactivate 3 or 4 cylinders. But you're seeing the result of higher average oil temps on the front half of the engine, hence the varnishing.
