Engine noise

     Hi all,
     
     I was wondering if any of you folks ('97 V6 owners in particular)
     have a rather pronounced TAP-ing sound from the engine. This noise is
     NOT the injectors. I know what they sound like. This sound is just
     like a sticking lifter or a hydraulic one that hasn't pumped up.
     For those who know what a leaking header at the head sounds like then
     you know exactly what I am hearing.
     
     It is twice as loud as the injector noises. Happens only when the
     engine is warmed up. The engine has 650 miles on it. The noise
     sounds like it is coming from down on the side of the motor,
     particularly the passenger side down low, or down the back. I've had
     my stethescope all over it but cannot find what is producing the
     noise.
     
     If you stand on either side of the truck by the side view mirrors you
     can hear it clear. If you stand at the front ... you loose it.
     
     Any ideas?
     
     Thanks, Matt!
     
     BTW ... For you guys looking for splash gaurds for your '97 4x4's with
     flares, try looking at a set of the hard molded ones for the '97 F150
     4x4. The F150's have a wheel flare and their gaurds are deep enough to
     accept the flair. They are not marked with any ford logos or anything
     that I could see so they would look pretty generic. I eye-balled
     these up on a new F150 in the parking lot and they *look* real close.
     Hope it helps some!
     
     BBTW ... is the fuel pump in the '97 Dakota V6 mechanical, or in-tank
     electric, or neither? What # are the fuel injectors rated? Are they
     pintle-type, or disc-type, or neither?
     
     Thanks again ...
     
     I'm in digest mode so if anyone wouldn't mind, CC'ing
     pmp@roadnet.ups.com directly
     I'd appreciate it as I'm anxious to hear about this noise and don't
     want to wait until tomorrow's digest.
     
     Later.
