My car is August 2004... It's running Castrol Formula R 5w-30 at the moment, but the noise has always been there, since 10000km I reckon. And I only hear it when at idle. When revving/driving/cruising, I don't hear it.

If you step on the accelerator on a wet surface and the Traction Control comes on - do u think u can hear a similar noise?

Just wondering if that noise is injector noise or/and brake pulsation noise (but doesn't exactly sound like ABS).

actually can u guys hear the noise inside yr car ?
or when u stay next to the bonnet or after the bonnet is opened?

Hehe, nope, because the noise is only at idle. Plus, then I took the video, the car was not moving.

Only when next to the bonnet (slightly). But it is most clear when you have the bonnet open (of course). You can't hear it from the inside.

that sound clip is loud, sounds like a diesel engine :eek:
sounds worst then my 14yr old civic.

TypeG car sounds so much louder after he went to the tracks,
I the valve spring is not design for high revs but more civilise use.

The reason why I ask is because, if your Traction Control kicks in when you put the foot down in the wet, essentially the injectors are being closed then pulsed again and power is shut down to near idle momentarily.

As such if you have the injector noise this woud manifest itself. But then again the brake caliper/calipers might work also on the wheels as well depending on wheel-speed sensor and steering-angle sensor readout.

i hear mine too when standing next to boonet, but it's real loud when cold start in the morning.... after that it's all good.

Just went out for a bit, came back and popped the bonnet. Engine was totally warm already. And the noise is the same. No change in volume of the tapping.

Sounds like Need tapper adjustment
and try to use a high grade oil for more protection like 10w-40
Some Honda Dealers do offer it as a Premium Grade oil
(10w-40 oil is used for there more expensive Hondas in Japan, all there s2000, NSX, Legend etc all use it)

My oil has been fully synthetic for the past 2 services. I was on 0w-40 and then 5w-30. I'll go back to 0w-40 at the next service (which is also the one for valve clearance adjustment).

So is your warranty due to expire in August? Let us know how you go with the dealer.
