Cummins 3938405 Valve Cover w/Oil Fill Cap for 1989-98 4bt & 6bt

A must for those that run an adjustable pump gear or have installed a breather in place of the oil filler cap on the front cover.

Kit Includes:

• 1x 3938405 Valve Cover
• 1x 3901895 Oil Fill Cap
• 1x 3936876 Oil Filler Cap O-Ring

This is the new style valve cover, so the stock valve cover bolt works fine but a rubber noise isolator # 3935449 should be used on this cover.

Same clearance as stock cover, so studs will work the same as stock cover.
