Want to know what's inside a Nissan TD42? Why they overheat or how to remove TD42 Injectors? Today on The Skid Factory we make a start on rebuilding the Legendary Nissan TD42 6 cylinder diesel engine. The TD42 was produced from 1988 til 2006 and available in NA and Turbo formats. They were fitted to Nissan's Patrol, Civilian Bus and large forklifts. The most common engine in Australia is the early naturally aspirated "Silvertop" engine which are now commonly fitted to later model patrols that suffer failures of the smaller diesels that are factory fitted. We sourced a high mileage Silvertop with plans to rebuild the engine to turbo specification and fit it to a 2003 Patrol. The engine is stripped down and checked for wear and we run through the design of the engine and it's variations over the years.
