Hello from Ocala. 2005 6 sp. roadster, 54,200 miles. I cannot find gaskets for the unit mounted on top of the valve cover gaskets ( PVC system ? ) . Chrysler dealer parts diagram shows unit but no reference for gasket. Possible to get at Mercedes dealer ? OR can a product like Permatex No. 1 or 2 be used ? Any help much appreciated. Thanks, Brad..
