Cummins 4BT Side Cover Billet W/ Breather (PDM-08407)

This billet aluminum side cover replaces the leak-prone factory tappet cover on the Cummins 4BT. The cover ditches the rubber gasket and seals directly to the block with RTV, eliminating the most common 4BT oil leak. A new-style breather and all the install hardware ship in the kit, and the machined billet finish doubles as an engine dress-up piece.
