Ok the car is an 88 305 gta tpi and the smog pump was removed and everything along with that now i got 3 hose fittings on the left side of the throttle body and dont know were they go 2 lines run down to the oil filter and 1 fitting throws out coolant and it looks like the lines connect to it but dont want coolan going into the oil so any help would be appreciated

2 should be for antifreeze. (I bought the coolant bypass-kit)
1 should hook to your Valve cover. (I think the PCV...but I have an 87)
I bought corvette valve covers for my car so things are swapped around.

how can you bypass it so the ones that run down the motor by the oilf filter are for coolant? could i just put a hose from 1 end to the other and by pass it that way? new to tpi so sorry for all the questions
You can buy rubber or plastic caps for the extra outlets.
See attached pic for the coolant. Just hook up your heater core lines to the manifold and the water pump.

i still need a pic i cant figure this out i hate hoses
No worries. I don't have any hoses hooked up to throttle body. I have rubber caps over everything.
i tryed if i do that the car just heats up and runs like crap and steam starts to come out the line that connects to the throttle body also my radiator shows the coolant is sitting there not circulating

Sounds like you need a waterpump, or a new thermostat. Do both...
FYI, the coolant going to the oil filter is the factory oil cooler... It doesnt go into the oil, but it does remove the heat from the oil.

ok thanks thats what it looked like but the coolant was flowing fine till all this was pulled off

So, how is everything hooked up currently? If it was working fine before, it shouldnt be the waterpump and has to be the routing.
i took the throttle body apart and found the gasket all cracked i made one out of gasket paper and sealer temporary till i order 1 and it runs now but only when i put the pcv line and 1 coolant line if i put the other line on then it starts throwing coolant out of 1 of the ports so i put a plug on that line but its running now at least i think it couold still be leaking though
