Not so sure about that. Without the CCV hoses, the idle could be adversely affected.

Even off road you might want to vent your crankcase. (the ccv deal) Venting the moisture that can make rust and doogie doesn't hurt anything. Also I suppose it's designed for that 2.4 mm 'vacuum leak", on that rear hose. Or it's 2.6mm. Also that 88 might need vacuum to the switch on the transfer case if you have a disco. (that "Y's" off the line to the bottle there near the trans dip stick)

Thanks guys. Mine was all jacked up from the PO. The line to the maf was connected to the front port on the intake and there wasn't anything connected to the rear of the valve cover. And the port for the maf on the side of the throttle body was open. Big vacuum leak.
