2002 Honda CRV Humming Noise

Hi,

Recently, I've took my 2002 CRV 4WD to an Honda Dealer for 30K Mile
Service. After the car was done, I've had engine leaking oil problem.
Took the car back to the Dealer couple more times for inspection,
diagnose, and they've resecured V-Tec Selenoid, replaced timing chain
cover and gasket valve to fix the problem. Now after back-and-forth
trips to the Dealer, I've got my car back. Hopefully, this time they
have fixed the engine oil leaking problem.

But, I now have the loud humming noise every time when I acclerate.
Whether driving on local with faster speed or speeding up on the
highway, this high-pitch noise is louder than my engine sound!

Took the car in this morning and road tested with the mechanics, he
claims that this noise was normal. But obviously, it wasn't there
before his service. We road tested another CRV (2004 is what they had
in the shop) and no such humming noise!!! But he couldn't do anything
more about it and I had to take my car as it is! What a service!!

Anyone know why I have this humming noise when I accelerates?

Any help is appreciated,
-Tiffany

Change the Dual Pump Fluid if it's over 30,000 miles. Manual is wrong
(your dealer knows it) Another test: Do a slow, tight u-turn to the left
in a parking lot. If you hear a sick scraping , dragging noise, it's the
problem I described. I'd have them do a drain-n-fill on the tranny as
well due to age / mileage.

Thanks I'll try that and see what I find out.
