Top-End Work or Major Overhaul
A top-end overhaul focuses on cylinder heads, valves, injectors, and turbochargers, and the parts list is fairly predictable. A major overhaul goes further into pistons, liners, bearings, and crankshaft work, where the final list depends on measurements taken after the engine is opened. For major work we suggest quoting in two stages: firm lines for items that are always replaced, such as gasket kits, seals, and rings, and provisional lines for size-graded parts that are confirmed once the inspection results are available.
Information That Speeds Up the Quote
- Complete engine model, for example 16V 4000 M93L or 20V 4000 G63, and the serial number
- Overhaul scope and the running hours at the time of overhaul
- Size codes or measurement records for liners, pistons, and bearings
- Target date for parts to arrive at the workshop
