Sweet, I dont have much blowby, the cars done 110k and never gone over stock boost but will be putting on 2530 soon.. just measured the barb ID and one is 11mm and the other 7mm.. what would be the best course of action..? increasing barb ID and having both cam covers T'd into one barb with an equal outlet sized barb or going with a barb for each cam cover and fitting another barb for outlet..? I have also put in some S/S scourers, in some stocking material, into the tank to catch more oil.. thanks for your help guys, just keen on answers to these questions and I'll be set
