Good day, after a recent trip to Mozambique the injectors on a Defender Puma 90 2.2 are damaged from the poor diesel quality. Landrover quoted 2200 pounds + VAT for the four. According to my research the Ford Duratorque TDCi 16v ZSD Puma engine is also fitted to Ford Mondeo, Ford Transit, Ford Ranger (2012) T6, Jaguar X-TYPE, LDV, London Taxi TX1, TXII, Citroen Jumper, Peugeot Boxer & Fiat Ducato. Does any one know of an alternate supplier for the injectors and/or can the injectors be stripped, cleaned, inspected and possibly repaired by by replacing the defectice inner parts? Any advice that could save some money would be greatly appreciated.
