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.
