Hello. I have a 2004 Transit, 2.0 turbo diesel panel van, 108k miles.
Last weekend I changed the glow plugs. To do this I had to remove the air resonator and disconnect the battery. Put it all back together and it started on the button. Job done.
Drove it yesterday and there is a bizzare sound coming from the air vent. There are four vents on the dash, two in the middle and one at each side. When it gets to about 2,300rpm there is a sound coming from the driver’s side air vent only, a sort of wind rushing type noise. This happens regardless of road speed or gear, will even do it when stationary.
Not sure if it’s connected to the glow plugs thing but I’ve never heard it before. The air filter lives on the driver’s side, right in front of the dash but all is fine there. I’ve checked the resonator again, all done up nice and tight. I’ve taken it up to 3,800rpm and it just keeps going, but as soon as I lift my foot off the throttle it stops. Can’t hear anything unusual from the outside, or not which I can hear over the engine at 2,500rpm anyway, can only hear it inside.
Any thoughts?
Thanks guys and girls.
