the PCV valve is new and does rattle when I shake it so I beleive it's okay. I have the hose from it running to the front port of my carb ( Edelbrock). I also have the breather on the opposite valve cover vented into the bottom of the air breather. I am thinking that I am getting some oil pushed out the dipstick tube, but nothing shows up when it's idling , only after I've driven it for a while. Thanks for the reply.
