[SPLATT]

Last night I heard a loud noise coming from the engine compartment. The noise was so loud that it could be heard in the passenger compartment at highway speeds.
I pulled over, lifted the hood and found the noise coming from the top of engine, back near the firewall. The noise seems to be under the intake manifold.
The noise sounds just like a baseball card that has been placed in the spokes of a kid’s bicycle. The faster the rpm’s the faster the and louder the noise.
Any ideas before it goes to the dealer?
