yes i was wondering if anyone could help me with my truck. i am replacing the valve cover gaskets and we got the easy side done the right side. but the left side i am having problems with we got the ignition coil bracket and the compressor out of the way. now there is a metal tube at the back of the motor that comes up from the bottom and hooks to well not sure wat but that then hooks to the upper intake where the throttle body hooks on. i couldn't get my pry bar in anywhere to move the tube a little and was wondering is it ok to unhook that metal tube. i wasn't sure if it was pressurized or not if anyone could help me i would appreciate it i would like to work on it again thursday. if anyone needs pictures i am going to take some tomorrow to show wat it is. but if anyone knows wat i am talking about i would really appreciate the help i wanted to get both sides replaced before i put my new plug wires and coil on.

Thanks,
Evan
