Oil from the turbo drains to it's own little sump tank, then gets sucked to the turbo scavenge pump where it gets pumped on to the main oil tank without going through the oil filter, right?
Or does the oil from the scavenge pump get pushed through the oil filter? I think only the oil coming from the scavenge side of the engines oil pump goes through the oil filter.

So maybe this carbon thats clogging the spray bars is coming from coked or burnt oil from the turbo bearing.
Maybe this is more reason to use synthetic oil and let it idle cool down a minute or so after driving.

Might be a good idea to take off the turbo sump and see if you can rinse any little burnt oil carbon chunks out of it...
