it's possibly going through as a mist and getting burned.
The intercooler is a good place to look as it collects oil easily owing to the pressure drop - if its no worse in there than your pipework then that more or less answers it, might be worth swapping the cartridge if a note worthy amount has collected at the bottom though.
Did you say previously there wasn't much crankcase blow-by? (as you would expect with a rebuild obviously)
