Engine Gaskets & Seals Overview
Gaskets and seals prevent leaks of oil, coolant, and combustion gases; a failed gasket causes leaks, overheating, or lost compression. Van Horn Truck Parts carries engine gaskets, seals, and O-rings cross-referenced to Cummins, Detroit, PACCAR, Mack, and Automann part numbers.
Match by your engine make and model and the specific gasket or seal location.
Mechanic & Fitment Specs:
- Match by: Engine make/model, gasket/seal location
- Cross-references: Cummins, Detroit, PACCAR, Mack, Automann
- Buying tip: Order the full set for the job (e.g., head, valve cover) to avoid repeat teardowns
