What color exhaust please? If black - and if the engine sounded as if it started working much harder at the same time - your hydraulic pump may have dead-headed.

exhaust was a light blue sort of colour not sooty or anything and lighter when no power applied. (hydraulic pump dead headed?)

Deadheading means the engine continues to drive a pump that's got a flow blockage on the output side. Blue exhaust usually signals an engine problem, one which causes oil to be burned in the combustion chamber(s). According to the link below: "This is generally mechanical failure such as problems with bearings, pistons, oil pressure, overheating, valves and more.
* Worn cylinders or piston rings
* Faulty valves or valve stem seals
* Engine over full with engine oil
* Faulty injector pump/lift pump allowing engine oil to be mixed with the diesel
The list is endless, it is best to get an engine specialist to diagnose the fault."
