Keating Machine 4BT Billet Tappet Cover

Fits Cummins 4BT 4 Cylinder engine, includes o-ring to seal against block and stainless hardware.

This cover doesn’t have a breather port so it is used if your engine has a breather elsewhere (e.g twin valve cover breather) and doesn’t need one on the tappet cover.

We do have one with a breather port available also.

This fits most of the roller lifters being used, but if you are using roller lifters be sure to check clearance between them and this cover before installation.
