Buyer's checklist
What to check before buying a used exhaust manifold
- Inspect the casting or tubular welds thoroughly for hairline thermal cracks, especially around collector junctions and bolt holes.
- Check mounting flanges with a straight edge for warping, which causes persistent exhaust leaks even with new gaskets installed.
- Verify oxygen sensor port count, thread condition, and EGR valve port locations, which differ depending on regional emissions equipment.
- Check that cylinder head exhaust port shapes (round vs D-port vs oval) match your engine's cylinder head design.
