Ok it's not the Bronco but the principles are the same. There is a clicking noise coming from the engine that has gotten louder recently, sounds kinda like a card in the spokes of a bicycle, noise speeds up and slows down with engine rpm. 1991 Plymouth Voyager(yeah minivan), 3.3L V-6, 253,000 miles. Runs great, doesn't burn a drop of oil and has plenty of power. All highway miles and very well maintained. PO said it was a trans bearing but when poking around with a mech stethescope the only place I can pick up the noise is on the fuel rail. First I was thinking valves but I figured I would hear that more on the heads and not on the fuel rail. Now I'm thinking fuel injector(s) but I need to know if a bad injector(s) could make that much noise. Any experience on this type of problem would be appreciated. Thanks.

yes it could be a bad injector, but i dont think it you would be able to hear it while driving. sounds like lifters to me. maybe not though

Definitely not exhaust. Can't really hear it while driving. Need to be stopped with the windows down or standing in front of it. When next to a building, like a fast food drive through it's really loud/noticeable. I was thinking lifters at first but it's not like any lifter tap I've ever heard before. It's more of a click than a tap like a lifter. And like I said the only place I can pinpoint it with the stethescope is on the fuel rail.
