found rattling noise under car.
 

One day i looked under and saw my air tube hose hanging, i didnt realize it, but since i removed my smog pump, the air tube to the h-pipe was just hanging there free with the steel end still on under the hood.

im welding the tube closed tommorrow, also what size caps for the back off the head, to cap that off as well....thx hope i never need this smog stuff in the future.:rolleyes:
