Whistling noise coming from valve cover on a 2001 Honda CRV EX AWD

Topic starter

I have a family member of mine who has a 2001 Honda CR-V EX AWD. I have done alot of work to get back in good shape. I went to T.T.C.N. for automotive technology and its a private party.

It's got a new timing belt, valve cover gasket, new pcv valve, valves have been adjusted.

It's making a whistling noise. If you put an engine stethoscope to the valve cover. That's where it sounds like it's coming from. 

It also keeps throwing codes P0172,P1129,P0301,P0302,P0303,P0304,P0300,P0170. 

runs rough. It also has a new Distributior,new plugs, and plug wires.

  • If you need a video that I recorded on my phone to try to find it. Just ask me and I'll send it.

This all started when the driveshaft broke and smashed the control wire (shift cable) and the downstream 02 sensor. It has a new drive shaft and 02 sensor downstream.

If anybody has any ideas. Just let me know. Any info would be greatly appreciated.

Thank You

Sincerely,

John Howell

Sounds like either a very new vacuum leak or a very old fan belt.  My bet would be the vacuum leak.
