[MORTY]

FIRST THING IN THE MORNING WHEN I START MY 2.5 UP I GET A HIGH PITCHED ELECTRICAL MOTOR TYPE SOUND COMING FROM THE DEPTHS OF THE ENGINE WHICH STOPS AFTER A COUPLE OF MINUTES.
IT IS A CONSTANT SPEED AND DOES NOT CHANGE WITH THE REVS OF ENGINE. I TAKE THAT IT IS SOMETHING TO DO WITH THE AIR INTAKE. WHAT IS THE PART AND CAN YOU TELL ME IF IT NEEDS CHANGING OR NOT PLEASE. IT DOES NOT DO IT WHEN THE ENGINE IS WARM.
MANY THANKS
MORTY

hi, i also get a similar (the same sound), upon starting from cold it lasts for about 30 seocnds and then cuts out. Like a motor/pump noise,

Where is the secondary air injection system located? connector to unplug etc.

Many thanks, pete
