Valve Cover Accessories

Comprised of 12 chrome plated screw and washer assemblies, one chrome plated oil filler cap and rubber grommets.

Now you can install a positive crankase ventilation system. These breathers are for the street enthusiast using Moroso valve covers and wishing to install a positive crankcase ventilation system. The grommets work with all GM PCV valves and will fit all valve covers with a 1.22 in. hole.

Oil control with a breather. Moroso breather grommets with integral baffles are designed for use with valve covers that do not have an oil control baffle system. They are made from oil-resistant rubber and will fit into any valve cover with a 1.22 in. diameter hole, replacing the OEM-style grommets. The built-in baffles provide oil control. Note: These breather grommets will not clear stud girdles.

Prevent oil leakage. These Moroso hold-down tabs spread the fastener load over a larger area of the valve cover flange to eliminate flange distortion and subsequent oil leakage. These tabs are available in several different finishes for a variety of applications.

The weld-in accessory you can use just about anywhere. Moroso weld-in bungs are made of 6061-T6 aluminum. They can be welded to aluminum valve covers, holding tanks, cylinder heads, oil pans, or wherever an NPT fitting is needed.
