ok...so we tried to start up my bro's 88 with a rebuilt 13b...but he kinda did a shoddy job in putting it all back together...so when we started it...we were checking the engine for vacuum leaks (they were EVERYWHERE) and i noticed that on the intermediate housing, right next to the oil filler tube, there is a spot for a tube to be put on there...where oil was spirting out of!!! what i need to know is...where should the tube that goes on there route to? i was thinking the charcoal canister...but my dad mentioned that it would fill up with oil...???
