I have blocked off the exhaust manifold where egr tube was attached. (Egr tube was cracked in half where the "accordian" looking section was at). What would happen if I just left the rest of the tube attached to the egr valve and left it open? Instead having exhaust gases going into my intake I would have fresh air going in when the EGR opens. Can this cause any damage to anything else? Car seems to be running same as always (Which is good), no CEL and havent seemed to lose any MPG. Havent noticed any pinging in the motor either. Any advice would be greatly appreciated. I am being lazy and dont want to tear off the top of the intake if I dont have to. Thanks
