2008 Tacoma Quad Whistling noise

Hi I am a new member basically a Nube. I'm looking for some advice on the possible cause of a "whistling" sound coming from the engine compartment. The exact location is hard to determine. It occurs as speed and increases intensity with increased RPMs. I am driving a 2008 Quad cab and I noticed the noise after I was on a muddy wet road and I hosed off the underside of the truck. Any help would be appreciated

Thanks

 

Most common are grill seal, weather strips on roof of cab and door seals. I've had all three.

Okay I will take a look at the seals to see if they are damaged... So we don't think it is anything major then?

 

Hard to say without hearing it. From what you've described it sounds like the grill whistle which is a super easy fix with some 1/4" drip line.

 

Some bastards installed a turbo when you were sleeping

 

lol thanks for your help.. Those look really good.
