No PVC. However, I bought a set of Mopar covers from summit racing and they only have one opening on each. I noticed my old covers had a breather on one side and a pvc on the other in addition to the fill cap. I am going to pull the valve covers and look to ensure that somthing is blocking the passage to the breather cap. do you think that i need to drill out a hole or somethning and make a pvc spot on the other cover?
Just curious. if both covers need to be vented some how.
Thanks for responding.
