Need to figure out where this starts and ends the hole on the heat sheild of the cat. would go up to the air cleaner. correct? and the other one goes up to the air cleaner as well?

]yea i got the same one under the hood. just i need everything else. well i cant get my photos on. but on the top of the valve covers there is a plaace for some hoses. Where do they connect to? and could i get some pictures of the different motors

im fixing a car for my father-in-law. He had the motor rebuilt now im putting it back together... what a mess. im looking for a detailed vaccum line diagram and what emission stuff a can get rid of.. please help... also its a 87 gl wagon and if i could get a couple of pics of the engine bay so i kno where everything goes would be great as well
