Disadvantages of the Land Rover 15P TD5 engine
The majority of issues are brought on by breaks in the wiring beneath the valve cover; the pump-injector drive’s cams and rocker deteriorate rather quickly here; fuel can seep into the oil as a result of damaged injector o-rings; the turbine control valve frequently malfunctions and the wastegate axis jams;
Another common occurrence is cracking of the crankshaft damper pulley and cylinder head.
