So my 1.9 us block, has been breathing pretty heavy since i installed it, its a 2nd had specialised engines block etc. My long term plan is to get it rebuilt by them and freshened up or just go Zetec turbo...

What can i do in the meantime to stop it blowing oil out of the breathers? I have a seperator and a catch can but occasionally i still get oil going everywhere. Is there an uprated breather system etc or something that may help?
