My car has the old 305 TBI in it. I have installed an open element since I bought the car. My ?? is the ube which came up from the valve cover on the left side and goes to the stock air cleaner what can I do with that. I have notice ther is a small amount of smake that comes out of there and i have started smelling it inside the cabin when I run the A/C fan. Any help would be appreciated.

 

Most of those air cleaner have an optional knockout to accomodate a fitting to attach the CC vent tube.

 

Could I put another PCV valve in the opening and splice a tube in to the other PCV valve line?

 

Another PCV valve will cause excessive pressure. Just install the origal PCV filter, it will look ghetto, but who is going to see it?
