Put on MP valve covers & now I have a little oil (blow by) coming out of the breather. If I was to put in a pcv valve would that stop it ? Didn't have that problem with the original valve covers. They had a pcv valve.

I'd be pretty hard pressed not to use a PCV valve.
Just remember to have the breather and PCV valve on opposite valve covers and the PCV connected to a manifold vacuum.
Might want to replace the breather too.

Thanks I put on the MP covers because I couldn't get the originals to stop leaking. I also put on a holley carb, runs so much better. Originally the PCV line went to the carb.

I said manifold vacuum, not manifold. The large bore port at the base of the carb is manifold vacuum.
On the Holley, it's the big port under the rear fuel bowl.

Got ya thanks

 

Run the PCV... That should fix it.
