i just had new valve covers put on my 72 340. i thought that would fix my oil leak (i'm not a mechanic) but it doesn't. it still spits oil out on the new covers. A guy at the local parts store told me that it would keep doing it unless i get pcv valve and line to the air filter or carb. Do i really need to do that or can i just replace the old broke filter (already done) and the air breather cap? If thats what it is called.
here is a pick of the OLD covers and you can see the air breather cap or whatever it is called.
