Honda variable timing control actuator VTC . inside look at Honda's VTC

[@kcfd28]

I just watched a bunch of videos on the VTC rattle and yours was the only one I saw that took apart the VTC and actually showed how it works. Now that I understand the VTC and what is happening, I am much less concerned. It is such a horrible sound...if only for a second or two. Thank you!!

[@vaamaamey6121]

I agree 👍 💯

[@lapin46]

a few things: VTEC, the thing you feel and hear, has little to do with the VTC actuator you talk about. VTEC changes valve lift by switching the valve rockers to engage the high cam cam lobes increasing cam duration and lift. The VTC actuator changes cam timing tuning the cam optimally for different loads and rpms. The start-up rattle is caused by the spring you have shown getting weak. The pin then is not able to lock the pin anymore during startup before sufficient oil pressure is present to fill the chambers. The pin is only supposed to unlock when sufficient oil pressure is present. At cold temperatures this takes longer to achieve. If you crank the engine a few times before starting it, the rattle disappears or only occurs very mildly as by cranking you build sufficient oil pressure to let the VTC actuator work without the lobes moving in an uncontrolled manner.

[@mikesproject4704]

correct for older VTEC. the 2012 year allows the cam shaft to shift time on the chain

[@lapin46]

@@mikesproject4704 VTC is variable valve timing. The chain driven cam gear internally rotates to phase the cam vs the “chain”. Even the latest K20C1 combines VTEC on the exhaust cam in this case and VTC on the cam shafts. VTEC combining VTC and cam profile switching was introduced with the K-series, so 2001. Honda is using it ever since, so even in 2023.

I've been working with a company who makes replacement springs for the actuator and in our communications they have told me that the timing chain tensioner going bad can be a factor that creates the rattle.

​@@lapin46 bro! was going to say all that but you said everything. Only thing I was wondering about and you actually kind of answered my question was the part about cycling the ignition a few times before starting to build up pressure to better control the vtc slop. Was actually wondering if that works because I haven't tried myself yet. Was unsure if the cycling would be worse on the cam or better until fix.

THANK YOU SO MUCH for this video and explanation!!! I've been going crazy trying to determine the source of that rattle and have heard all of the speculation surrounding it. From: 1. It's the timing chain rattling against the guide, about to jump a tooth because it's stretched. 2. The oil level is low, or the type of oil is insufficient. (Although I do recognize that oil plays a part). 3. It's the chain tensioner failing. I have had Honda mechanics swear that it was the timing chain making this noise, but I was never convinced of it. Now I have what I was searching for, thanks again.

Excellent explanation. Thank you! I have temporarily solved the issue by cycling the key in the ignition 10 seconds on, 10 seconds off then 10 seconds on and start. I have had no rattles in years. I found this solution on the internet. I wished I knew what this process of cycling the key does to the VTC oil control solenoid it cycles. I believe that the solenoid releases the oil pressure inside the VTC letting it lock in place before start. I have the replacement spring in stock but for now, after 4 years of no rattles I am willing to wait. No need to replace the whole VTC actuator. Apparently it will have the same issue later on.

One temporary technique I did in cold weather was to bump the starter a few times before really attempting to start the engine. Doesn't seem to rattle on starting. I think by bumping the engine over builds enough oil pressure to reset the vtc and take up the chain tension.

Great video. Love the breakdown of the internals. I just changed my VCT in my 2008 K24. The one thing that many videos don't reveal is sometimes the VCT can be stuck in between locked and unlocked like mine was. I inherited this vehicle from a family member and I believe the VCT has been rattling for the last 150K miles or more. I had to use some innovation to get the new VCT to line up correctly after torquing it down and locking it. It's as quiet as any new Honda on startup now. I do believe that over time, the resonance of the frequency from a failed VCT will cause premature chain stretching. Just my opinion though.

[@mikesproject4704]

[@geraldmenard6164]

Push the gas pedal down to the floor. This will shut off the fuel injectors and prevent your engine from starting. This will allow you to crank over your engine long enough to build up the oil pressure without your engine starting. Release your gas pedal after around 5-10 seconds or so (dependant on outside temp and engine condition) and your engine will start without the rattle or significantly less rattle because the oil pressure was given enough time has reached your VTC actuator.

Fantabulous sir

[@carbideblue]

It (the rattling on cold start when the lock pin is not locked as it should be) DOES do damage. It will destroy a timing chain in very little time.

[@mikesproject4704]

i am going to say no on damaging the chain. but over time you will wear the inside of the actuator. and will effect oil flow and metal floating in the oil.

[@caseyalexander2244]

No it does not. Mine has been rattling for almost 200K miles. What will happen is it will affect the chain tensioner if anything at all. Since the inner mechanism that is bolted to the end of the intake cam is designed to move independently of the chain and outer gear I am not one who subscribes to the idea that the chain becomes stretched or damaged because of the rattle. That happens for other reasons, usually lack of maintenance and mileage, and many of those miles with low oil level. The chain can and does stretch, and the tensioner could be a part of the rattle. I think people with stretched chains and tensioners going bad are the people who have replaced the actuators entirely and had the rattle return in short order. To explain - since the recess that holds the pin in place is connected to the outer gear in a roundabout way, if the base timing is off due to chain slack or stretch, the recess will not be clocked in such a way that the pin can locate itself as it should in it. So I believe this is why it's not locked on start-up as it's not necessarily locked in the recess on shutdown. The pin could be partially covering the recess, even just millimeters from being seated, but it's not so the inner mechanism is free to rattle.

That’s an interesting thought. The stock springs are much narrower than the pin hole.

I’m having the same issue finding the right Torx bit. Is this for a 2013 Honda. T 27 doesn’t work

[@Daniel-xq7ny]

I didn't do my CR)V yet, so I cant be sure of the size, but its a 5 point style Torx, (not a 6 point). See link below, (amazon)

Hi, what happen if keep using this defective vtc for long time?

[@mikesproject4704]

the edge was starting to show a little wear after 6 months. i assume if it wears too much the timing could get stuck in a weird position you might lose fuel economy or a little power

Means that if i dont have money for fix it, it wont damage any part?

[@mikesproject4704]

I ran it for 9 months and there was little wear, so 2 or 3 years would be my guess before you run into problems from it.

I was having same prb.. But couldn't notice in the beginning... Atlast the engine started jerking n the timing chain cover also got broken.. I found it when the mechanic opened the cover.. N it will cost u more as well.. So, better get the vtc replaced before it damages the whole system
