DSE Loosing turbo?

At 4500 rpm I get 160 kPa reading from my MSV2, instead of 220 kPa or so. Lots of whitish-blueish smoke both mostly tick-over but also during driving. Going uphill when the auto box downshifts I get a puff as well. Taken together, should I be looking to replace the turbo? if yes, where to get a rebuild kit?
thanks!

So yer losin 80 Kilo-Pascals .. sounds like a seized bearing in the turbo me thinks!!

Or a split hose or a gummed up intercooler. If the turbo has gone, I don't think it's a DIY rebuild job, you need one from a scrappy or a new one.

Is this the same car that you have bee playing with the injector pump?

Datatek, thanks. The intercooler has been throughly cleaned when we did the FIP.
yes, the very same jewel...
It has 240k km on the clock, and smokes a lot. It looks like the engine is good (by the usual superficial tests of the dip stick, observing smoke level at the oil filler cap and lack of suspicious noises), and the smoking was not affected much by the injection pump swap (and yes the 'new' pump still needs to be adjusted properly...). Could the low turbo pressure be related to the FIP?
thanks.

Wait until you have set static or spill timing on new pump, before you start looking for resons why it smokes. Spill timing is critical on a diesel engine, incorrect spill timing will cause smoke.

wammers, what is spill time? do you set it separately from the static timing?

Just a name for the same thing. On old mechanical pumps spill timing had to be set by hand using a swan neck pipe fitted to No 1 injector outlet. It is basically to set the time the spill port shuts and fuel delivery starts. Which is critical, that is why you have to set your rotary pump with a DTI to the specs listed in RAVE. Unlike the old mechanical pumps were quantity of fuel was then adjusted by a govenor, your rotary pump has EDC (electronic diesel control). So after static or spill timing has been set with your DTI, it is then adjusted automatically dependant on engine speed, load Etc. This is done by the engine ECU fed by signals from your MAF, Inlet air temp, Engine Temp, MAP and crank position sensors. But the static HAS to be correct to give everything else a reference point to work on. Other wise it will smoke like a factory chimney.

OK, thanks for the briefing. I am ready and will do it hopefully this Thursday. Keep posted...

Hi folks,
Ended up deciding to redo the turbo. Not so much the missing pressure as the thick white smoke coming out of the exhaust. It was so bad i was stopped regularly by other drivers upset at the damage i was inflicting on our precious environment. Went to a LR specialist, he took the hoses off the turbo, revved the engine, and within seconds you could easily see the oil coming up through the turbo out port (the compreessed air side). It was definitely time for a new turbo.
Ordered the rebuild kit fro G pop shop, got it, and took the turbo out. I could not believe the amount of junk in it. It was a miracle it was even rotating. After a couple of days in various cleaning solutions only half of the deposits came out, so I realized I can not continue the rebuild myself. So, I got an exchange unit and installed it in the car.
Now, after some adjustments, the car runs fine and, more importantly, there is no trace of smoke off the rear end, thank god.
Conclusions? Don't under estimate the turbo as a cause for whitish smoke, even if it does not whine and the car runs fine.
