I just bought this 67 C-10 and i have some bugs i need to work out.The engine has some blowby but the PCV valve is not working.It is hooked to a port under the choke and when i pull the hose off going to the valve and stick my finger over the port on the carb. there is no vaccumn at all.Where can i get a vaccumn source for the PCV valve?I also have oil puddling at the intake bolts on the right side as shown in pictures.Where could the oil be coming from?
