88 runna, 22re. Around about 2500-3000 rpms, the engine starts to "howl". Sounds like a freakin vacuum cleaner.

I know when this noise was made in a Ford 4.0, a dirty EGR was usually the culprit.

Any suggestions??

my 20r does that too when i get her revvin, then sound of air blowing is louder than my exhaust by far.

fanclutch siezed?

its not like a screaching of mettle its like the sound a leaf blower makes but without the gas engine, atleast thats what mines like

Its probably just the fan, once it gets warm and locks up the thing will make a ton of noise. In my girlfriends B2600i, it makes SO much noise I can't even hear the engine, the fan blades are really steep, and push a TON of air.

My truck did the exact same thing. it was from a sticky fan clutch.
