I got my car back from the dealership today - had the following done:

- timing belt
- drive belts
- radiator flush
- hepa filters replaced
- oil change

Took the car out for a spin, engine sounds like it has a low rumble/hum to it.

Nice thing is it seems like one of the techs decided to get rid of my 1st gear clutch squeel :-)

Car picks up better now, but the low noise was not there before.

I'm at 122000 miles now. This is my second timing belt. Went to Arrowhead Honda in Peoria AZ. They did the last one too. Have always done a fantastic job in the past.

Ideas? I did a search for engine hum but didn't find anything for a 6th gen.
