![]() What he said. I'm used to GM's that had the valve in the valvecover...I got all confused when I first bought the Mustang. A tip though....never plug BOTH holes. You need at least one of them venting, otherwise you'll buildup crankcase pressure which can potentially cause blowby. Plug one and run a breather on the other.....or put breathers on both. Since you won't be able to reuse your stock oil cap and PCV return line. Oh, and you DID plug the manifold fitting right?
