    You can't. But why would you want to?

      because i have more oil than i would like comming from (possibly) the turbo seals and i believe a blocked oil line can do that...but also reading the FAQ its a PITA to remove....


      therefore if I could test it I would eliminate it - and save myself a PITA job!

        Just two bolts remove the turbo drain line. You will also need to remove the wastegate actuator rod. Be sure to have the lower o-ring and a new gasket for the upper end. If the engine is cold, it is an easy job. If you start this job while the engine is not, it will be cold by the time you are able to complete the job.

        The previous owner's of my wife' 745T neglected oil changes, the the oil galleys in the block were full of all kinds of old oil deposits. The turbo drain line, while having some crud in it, was free to drain. I doubt that yours is plugged.

          Thanks John,

          I think I have diagnosed the seals on my turbo are shot...

          its using about 1/10 litre of oil round town, but on a fast run (75 ish) it uses 1/3 -1/2 litre and most of that seems to be ending up in the pipe work from the turbo to the throttle body...though curiously eneough only get a table spoon at MOST out of the intercooler...

          the plugs look as though its been burning a bit too...

          Im going to compression test the engine before i make a decision though..no point doing the turbo if the engines not healthy...

          Haynes says to pull the LT on the coil and the wires to the fuel injectors first..what are your thoughts...?

          Im also getting cunning and have fabricated a pickle switch that i can wire onto the low current side of the solanoid so i can crank the engine without the ignition on.. can you see any downside?

          your opinions really appreciated as always...
