I recently posted about a loos of power on my disco 300Tdi. It turns out that the cause was a small thin pipe that runs somwhere around the back of the engine block and I think into the injector pump.
Not sure of its workings, but it was enough to loose all signs of turbo power. New pipe was fashioned (LR South Africa quoted R550 and six weeks delivery) and this seems to have cured it.
Problem is that wagon does not have the power it used to. Definitely more, but nowhere near full power. I battle to get up any kind of hill over
90km/h.I am not sure what sort of nick the injectors are in, and I assume that fueling problems are beyond amature diagnosis, apart from leaks which I do not seem to have. So focusing on the turbo, are there any easy -read cheap - ways of plumbing into the pressured side of the turbo and getting a reading of what sort of boost the turbo is developing? This seems the most obvious candidate for power loss considering the levels of boost the Tdi runs.

PS: I replaced the rubber hoses on the intercooler etc when I sorted out.
