Now..the other noise 2006 Accord v-6

[tony]

Now that I have the P/S pump quiet (finally)….the other noise is driving me nuts.

When cold in the morning, startup is fine..quiet as a sewing machine.

Under light load (barely on the throttle) I hear what sounds like marbles in a can – very mechanical sound, Varies with rpm. Not detonation (like my 83 for Ranger which was detonating). I eliminated the pullys as the culprit by spinning all with belt off when chasing this P/S issue. The timing belt and tensioner were replaced. So I am looking elsewhere.

Aside from adjusting the valves to rule that out, what else is it?

The Variable Timing actuator? How to you isolate that one?

I run semi 5w20 and change it at 5000. 100,000K miles now. 1st owner.

You may want a mechanics stethoscope or a screw driver to help with the noise.

That particular engine doesn’t have variable timing actuators. It uses a second set of rocker arms and magic.

Given the age and your description, it sounds like there’s a decent likelihood of the valve needing adjustment. All you can really do to confirm it is use a stethoscope and determine where it’s coming from.

But wait, there’s more. There’s a couple of videos and a V manual for adjusting the valves on your engine.

Magic? I knew it.

I’d rather hear it when cold than smell the valves burning. Gonna leave that one alone.
