Get this checked immediately, it could be the timing belt tensioner and if that was to break, you're looking at thousands of dollars in repairs to the engine. How many miles do you have on the vehicle?

Did you have the timing belt replaced at the 105,000 mile service?
ANSWER by on April 05, 2010
115,000 miles

The noise I hear at most all times sounds IDENTICAL to a car horn being muffled by insulation or towels. Seems to be coming from the firewall side of the engine/compartment. Thanks and sorry for r...
