Overhaul & reconditioning

Cylinder heads

Cracked or damaged cylinder heads are first assessed to determine whether a repair is economically worthwhile. Cast iron cylinder heads from almost every engine type can be handled.

Procedure

1. 1Assessment of overall condition and of the economic viability of the repair.
2. 2Verification of material compatibility between the head and the filler metal.
3. 3Controlled preheating and cooling, matched to how each material reacts.
4. 4Repair by cast iron stick welding at a stabilised temperature.
5. 5Precision machining to the manufacturer's original tolerances.
6. 6Pressure testing and crack detection on every part.
7. 7Refurbishment or replacement of seats, inserts, bolts and mounting plates.
