I have a 1992 Montero that recently started making the strangest noise.
I noticed this water noise coming from the dashboard area about 9-10 days ago. It started out really quiet but it's getting louder each day. I don't see a leak (aside from the noticeable oil leak) or any missing hoses. Its as if water is trapped inside the dash board above the steering column. It doesn't happen every time I drive and I can't seem to figure out what triggers it. At first I thought it only happened while accelerating slowly (like in a parking lot) then I thought it was worse when I was driving up hill. However its happening more often and not just on an incline.
