FAQ

Q1: Does this gasket kit include a head gasket and valve stem seals?
Yes, this is a full gasket set. It typically includes the cylinder head gasket, valve cover gasket, oil pan gasket, intake/exhaust manifold gaskets, and valve stem seals. However, please verify the exact contents of the 4089648/3389169 kit for your specific application, as some variations may exist.

Q2: Can this kit be used on a Cummins 4BT engine in a Ford F-Series truck?
This kit is designed for the Cummins 4BT and 4BT3.9 engines, which are sometimes adapted into Ford trucks. However, fitment can vary depending on the specific vehicle adapter plate, oil pan, and timing cover configuration. We recommend cross-referencing your existing gasket set or consulting with a specialist to ensure compatibility with your specific swap setup.

Q3: What is the recommended installation procedure for this gasket set?
We recommend following the official Cummins service manual for the 4D102/4BT engine. Key steps include: cleaning all mating surfaces thoroughly, applying thread sealant to specific bolts (if required), and torquing the head bolts in the correct sequence and stages. Using a new set of head bolts is also strongly advised. If you lack experience, professional installation by a certified diesel mechanic is recommended.
