Yes it goes to a PAS resevoir which is by design perfect for the job - take a look at one if you can.I filled the resevoir with stainless pan scrubbers which collect the oil vapour and consolidate back to oil.
The base outlet goes to a Y piece and returns to the sump, the top of the resevoir has a pipe fitting that goes to a small blow off filter.
It all works very well, drops no oil from this source and keeps the intercooler and related pipes clean.
