WE could be forgiven for thinking of the Puma Defender engines as modern diesels. The reality now is they were simply the latest technology back in 2007; a long time ago now, and all Puma Defenders will now have seen many operating hours.
They are, on the whole, a reliable and well-suited engine for the Defender. As you would expect after more than a decade’s use, some are at the point where they’re starting to have issues in areas such as injectors, turbocharger and Exhaust Gas Recirculation (EGR), all of which are repairable by swapping the parts for fully-functioning units so the engine can operate to spec again. Any engine has an intended operating zone where it is designed to cope with normal temperatures and pressures.
But anything that prevents proper lubrication or allows excess heat will cause that operating bubble to be exceeded, and damage to components occurs quickly. What do you do if your engine develops more serious problems, such as crankshaft issues, or is run low on oil after excessive timing cover oil leaks?
Rather than fit a rebuilt engine of unknown quality or workmanship, there is
