If you let your oil get dirty and crappy the crankcase breather is sucked in to inlet side of the Turbo and with condensation in the rocker box in cool temps especially on short stop/start trips it can gum up the inlet tract right through including the turbo , intercooler and map filter with a mayo like cream oil/water mix . which can harden on the turbo as it gets hot .
Ive never seen that in a Diesel engine, it’s far more of a problem in petrol engines due to the larger amounts of water vapour produced. Even if there was such a build up of such crap in the intake would you really want to flush it through a running engine?
