Engine ticking sound video. Valve adjustment needed?

mr_wang · Apr 17, 2016

Hi all, '05 touring with 79k miles. Runs ok however I am not sure if this sounds normal or I need to have the valves adjusted? Just changed plugs, oil and ATF and cleaned EGR Valve. I just purchased the Van last December. New to Honda and liking it. Please see video taken underneath the engine.

Thank you

Exhaust leak?

Piston slap?

Maybe a hydraulic tensioner

Not sure where to start. Dealership?

Do you hear that same sound while driving, or is it only at idle? If only at idle, is it only after a cold start or always?

Good point. It's only on idle sir.

Mine has the same tick. It does it at idle with warm engine. When it is cold there is no tick.

Sounds normal to me

I was thinking it sounds just like mine too...even after adjusting the valves.

Probably injectors?

I don't think its the injectors. Have a mechanic look at it.

Check your spark plugs. Mine was ticking loudly from front bank. It turned out the three front plugs were lose. Tightening them reduced the tick. The rear bank plugs were ok.

Checked all the plugs and I noticed the 5 & 6 coils replaced at the dealership they are Hitachi? I now have misfires all cylinders random. Could it be the non OEM coils?

Hitachi? That maybe your problem. Honda's ignition system are sensitive.

Sounds to me like there might be a slight knocking. Does the sound disappear at around 2300 RPM? If so, might be your timing belt tensioner has seized. This allows the timing belt adjuster to knock against the seized tensioner. If this is it, the sound will gradually get worse until you think there are probably serious engine problems.

I will have dealership change them to OEM this weekend and see if it will go away.

Yes it runs perfectly on that rpm range. Could this be also the cause of misfires? Will take it to dealership this weekend. $$$$ again.

When the knocking on my engine got bad it did start throwing codes, but no misfires. I was getting the following:
12-1, 14-1, 16-1, 18-1 – These are all ABS codes for malfunction of the four wheel speed sensors.
83-1 – ECM/PCM Relation Malfunction
P0344 – Camshaft Position Sensor A Circuit Intermittent B1. This had three instances; under Transmission, Engine, and Global.
All these codes went away upon replacing the timing belt tensioner and stopping the knocking. I’m guessing that the knocking was causing so much interference that the computer wasn’t sure which codes to spit out. Of course, if you look at this thread (http://www.odyclub.com/forums/9-problems-concerns/268257-timing-belt-replacement-misfires.html), you will see that is when my misfires and the real problems began.

Good luck with the dealer! I try to stay away from them as much as possible. I have worked with four different HONDA dealer service departments for a few different problems (all under warranty). I can cite examples of how each of the four proved to be incompetent in servicing my HONDA vehicle.

I cancelled the dealership appointment this Saturday. I will take it to my well known shop instead. One more thing weird is I have been using 91 octane and threw codes since I used it. Then yesterday I filled 87 and ran smoother but still have the codes. I think I drove the Van around 45 miles already and the codes are still there. Anyways I will have everything checked to see what's wrong. Thank you all for your ideas.
