A couple of questions about my truck hoping someone that knows these engines could answer. My truck runs ok except for the blow by(fixing at a later date). Just had someone swap engines and noticed under the air cleaner there are 3 gray lines that come up from the underneath section of the engine (between the air cleaner and where the plug wires connect to, rotor i think)). There is only 2 connected and third line is cut off. Is this supposed to be connected, or with the difference in years not needed? Was trying to troubleshoot EGR codes since the service engine light was on. What do the 2 gray lines from the lower section of the carb go to? Thanks for any insight.
