welps.. i just purchased from my father a '91 dodge dakota 4x2 extended cab with a stock 5.2l 318(Holley throttle body).

i'm kinda glad cause it only cost me $500 and this truck has been in my family for a rather long time..(bad at math but i'm only 19).

anyways my Q is if you guys have had troubles with the emissions pump in these trucks? the one in this one loves to squeel when it either A gets wet or humid weather.. also.. ever had this happen;the pipe connecting to the emmisions pump that runs alongside the cat, the welding on it came off.. leaves a very annoying rattlin sound...

Emissions pump?

The only thing I can think of that has moving parts and is for emissions is the PCV or EGR valves.

There is no emissions pump on that truck(aka smog pump, air pump), the line off of the cat runs to your EGR system. Are u sure its not your power steering pump?
