Hey people Im new here and love this forum. I own a 67 coupe with a/c..and a 73 mach1..My question is this. Can i plug the holes where the pvs and tcv,,went? I rebuilt my motor 351 c and replaced the intake with a elelbrock intake as well as carb. The old setup to route hoses from those valves are long gone..They probley havent worked for years is my guess. Now even if i could some how set ip up..i cant purchase new valves..cause here in Canada..they simply dont exsist..they dont sell them anywhere !!.They are discontinued parts that have been off the shelf for years. So what shall i do..can these be pluged with out causing overheating?..I do have a 3 core rad from a old lincoln shoe horned in it ..and the temp outside never really gets above 75 anyway...but if anybody can carifiy it would be appreciated...thanks
