Rebuilt vs Used Mercedes Sprinter Engine: Real-World Cost, Reliability, and Longevity Compared

typically stripped down to the bare block, then rebuilt using OEM-grade components, with machining work carried out to precise tolerances. This process often includes cylinder head resurfacing, crankshaft grinding, oversized pistons and rings, and compression testing in line with British Engineering Standards. When done correctly, a rebuilt unit offers predictable performance and is far less sensitive to hidden wear that can shorten engine life.
