The 2 little elbows at each side on top of the air box have no hoses connected to them and one is blocked off with a little plastic cap. I need to get this all sorted out as i want to get my car working to its best after spending all this money on her. I know these questions have probably been asked before but i am desperate for advice on my final stage of getting the cold air to get into the airbox.

the elbows are supposed to have a pipe on each running to a plastic collector at the bottom/back of the airbox near the oil filler neck... its designed to feed oil vapour from the engine upto the elbow - then into the carbs and through - part pollution control.. on my car there were no plastic ends in the elbows but a metal insert that screws in - the tube attaches to this... you could change this and run some sort of catch can arrangement instead (although technically this might get u defected)

My mechanic reckons because i am getting hot air into my airbox it is causing my spark plugs to foul up and burn oil.
|
that doesnt sound logical. have you got the right plugs in? try ngk 6 instead of 7's that might help with the fouling... either that or the carbs are not tuned right. my car ran fine for years without a direct cold air feed - as do many older carbd cars

I know all i need is soon tubing to go from the square box to beside the passenger side headlight behind the grill to get cold air into the airbox, where do i get this tube and is it a special kind of material?
|
nothing special just go to a place like clark rubber or similair. depending on the size of pipe it should cost about 20$

but what about the 2 elbows on top of the air filter lid, are they supposed to be blocked off or i noticed on most pictures that they have hoses coming from them and they disappear behind the engine, where do they connect 2???????????
|
they are part of the emmisions crap that came on allot of the cars. from memory they fed vapour from a carbon canister...dont worry about them - plug them up - cork will work if u cant get the rubber inserts. once you've done that it wont be sucking in unfiltered air !
