Keating Machine | 4BT, 4 Cyl Tappet Cover with Breather – Fits Cummins
Fits Cummins 4BT 4 Cylinder engine, includes o-ring to seal against block and stainless hardware.
Breather will not clear the factory fuel filter that is screwed into the cylinder head.
So you must have the fuel filter relocated to a different location to use this cover.
We do make one that doesn’t have a breather hole if your engine has a breather elsewhere and doesn’t need one on the tappet cover.
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.
