Valve adjustment

[Ibol13]

Yeah, I agree it's definitely tickier when cold, but that's true with almost any engine, and considering how the engine is designed I would be surprised if it didn't tick when cold.

My engine doesn't get a lot of use, and it's extremely quiet, so every oil change I do the song and dance of hearing how much it ticks in maintenance mode and then obsessively comparing it to recordings online.

It is very much a sewing machine engine noise, but I believe that is normal, especially for a Honda.

I personally think scifi blender better describes it. I honestly quite like the sound of it though.

I enjoy that I never hear it while driving. I usually only know it is operating because of the screen.

So bizarre how some people here say they can't hear it, some way it's really loud. I personally can hear the engine up to about 35 or so if accelerating relatively slowly, at a normal battery SoC.

My driving is almost all electric. I really only use the engine on the highway.

If I turn off my music, I can hear it below 45 mph (the "gear icon" direct engagement speed), but it's still very quiet. My previous car was a gen 2 Toyota Prius, and it was both louder from road/wind noise and had a louder engine.

I will say, when I was driving up huge mountains in southern West Virginia, the engine was louder.

Sorry to dig up an old thread but I figured I would comment here first before posting a new thread.

I am over 170k miles now. I have not done a valve adjustment yet but I am going to soon. There is some conflicting information in this thread about the intake valve being hydraulic. Has anyone confirmed if both the intake and exhaust valves are manual adjustment? Also, is there a best practices method for preventing an oil leak when replacing the valve cover?

Edit: I do work for a Honda dealership but I didn't want to bother my technicians. I was able to find the procedure on the Honda Interactive Network. Both the exhaust and intake valves are adjustable.

My only concern is creating a leak when I reinstall the valve cover. I will be sure to ask a technician were to apply the Honda bond to prevent any leaks.

Thanks for the specs. Presumably, those valve clearances are for a cold adjustment. On racecar engines the initial setup obviously was cold, but we always did a final hot adjustment after breaking-in the engine on a dyno.
