Ticking Noise: Valves, Lifters, or Timing Belt.

[Jay M.]

Hi Forum,
Nice to meet you here. Though I’m new, but I’ve been a big fan of Eric’s on youtube for a while. I enjoy working on my cars, such as changing fluids and minor repairs. For challenging jobs (such as timing belt), I’ll pay a professional do the work.

Now I noticed a ticking sound that gets me concerned, as in this Youtube video:

The ticking noises appear when the car is warmed up, get quite obvious when pressing on the gas padel. I first noticed it 3 months ago and thought was exhaust shield. Now I think the noise is from the engine, on the side where the timing belt is.

My car: Honda Accord Hybrid 2005 V6 115K miles
Regular oil change with synthetic oil. The car is running fine.
The timing belt, water pump, and tensioner was replaced about 6 months ago.

My question is: is this valves or lifters? or something with the timing belt? or something else?

Doctors, please help.

Thanks in advance.

Hey MJB I am not familiar with these car but the my personal experience is that it sounds like the lifters and they need adjusting but that is my opinion.

I would first try and isolate the noise.

Are you using the correct viscosity oil?

As for the valve adjustment, i believe the service interval for those vehicles is 100k miles. I would see if you can find anymore info online.

We do not service hybrids where i work as no one is certified to do so.

Thank you! A friend of mine said the same thing, probably the lifters. I’m thinking about adding Seafoam or Marvel Mystery oil to the engine oil to see if there is any improvement. I’ve never been a fan of these “oils”, just that I’m about about to change oil soon anyway. Any downside should I be aware of?

I tried to listen from different angles. The ticking noise seem from the engine. I even retorqued all the spark plugs to make sure it’s not due to loose spark plugs.

Yes, I’m using Castrol Edge Synthetic 5w-20 and K&N filter.
Yes, it is due for valve adjustment. Just want to make sure it is needed because it’s going to cost $500+.

This generation (2005-2007) Accord Hybrid has virtually identical engine as regular V6. The hybrid module connects to it and adds about 16hp, that’s it. I think the valves, timing belt, etc mechanical components are the same as regular engine.

Thanks.

First, your engine doesn’t have lifters so adding seafoam or other ‘cleaners’ isn’t going to do you any good. In addition the timing belt on that engine has an auto tensioner so in theory the timing belt should remain at the proper tension. To my ears it sounds like the valves and it probably wouldn’t hurt to adjust them. It just so happens I’ve done a video on this process as well as a video on changing the timing belt on that engine. One last thing, if you’re running synthetic you might switch back to regular oil, many times running synthetic on an older engine can cause noise like this as well as oil leaks.
