Default Someone help please!

On the passenger side of my 85 Throttle Body there are 3 outlets but one was always capped of and I never thought much about it, coolant, valve cover breather line, AND! I cant find where the other line goes but when I had my Throttle body apart last night I could see that it performs some sort of vacuum function and should not be just capped off I think. So I would like to fix this

it could be that the coolant was bypassed. i also believe one line goes to the pcv on the valve cover. look in the front of the bypass and see if a line is capped there also. if it is, it's most likely a coolant bypass. (free mod)

yes, there are three big holes and one itty bitty hole. The itty bitty one is for vacuum I think, but I have mine plugged. The highest of the "big" holes is for the PCV system and can be plugged if you're not venting the crankcase into the TB. The bottom two are for coolant flow and can also be unused, so long as the coolant is routed from the front of the base of the intake manifold to the heater core (which it probably is).

Just make sure they're all plugged and you're good to go... :lol:
