Hey guys just had my rb30 bottom end freshened up 2 weeks ago, it's all run-in now with fresh penrite hpr10 (15w50) now the issue is oil pushing into my catch can when boosting/high rpm. I have a 1.5mm restrictor in the block & the back one blocked off.
I had my catch can draining back to the sump with the 2 the rocket cover lines going into the catch can & another line going to the turbo intake with a 3mm restrictor, when I had this set up it was blowing ashit load of smoke so I've not blocked the line off to the turbo into & run the catch can oil drain into a bottle to catch any excess oil but it's pushing it out hard & making a oily mess.
Anyone have any idea what's going on?
Done a comp test & it's all within 130-150PSI
