the pipe that i think u are talking about goes in the back of the heads right??? if you have the motor out take that pipe off and plug the holes. i left mine on becuase i have not taken out the motor yet. everything else associated with the smog pump can go, including the coal canister located in the front left hand side of your engine bay towards the bottom. also, you are going to have to re-route your belt. if you leave it running the factory way then the belt will rub towards the top. (or at least that is the problem i had) i cant quite remember the way to route it but as long as the crank and water pump are turning the same way as they would stock then you will have nothing to worry about.
ok im going to try to explain this the best i can so bare with me. if you look at the factory routing, the belt goes over the water pump to the right then goes back around the crank to the left and looks like a backwards "S" now, if you reverse so that way it looks like a normal "S" it will go over the water pump to the left and under to the crank. the belt should come strait from the bottom of the crank to the alternator. in stock form it goes from the water pump to the alternator. make sense, or did i just confuse you?? becuase i know i just confused my self. man my brain hurts
