ilmor Posted January 27, 2013 Report Share Posted January 27, 2013 The new 4.6 L covers did not come with any instructions, which is not too surprising as their installation is pretty straightforward. I do have a question however. See the photograph below: The large hose is the intake to (driver side) valve cover connection. The connector at the top of the pic attaches to the intake. Apparently the new cover does not have a PVC valve integral to the cover such as the original cover does. Upon startup after installing the new cover there is a huge vacumn on the crankcase. Checking the parts provided with the new covers, I see that there is a PCV valve and a hose connector (pictured). I am assuming that I am supposed to cut into this hose, insert the new PCV valve and then reconnect the hose. Is this correct? Quote Link to comment Share on other sites More sharing options...
