not necessarily the best but works very well with my car

mine has a turbosystems tank/seperator....



as you can see it dont have the cam cover tapped, runs 2 bar boost and uses sod all oil (say half a litre per 1000miles), only once did it spit some down the inner wing out the breather after some grief and thats cos i overfilled it

tried and tested mate dont believe the hype

PS you may need to check with karl if this type of oil return to sump is ok for you i.e. i run a windage tray and you dont

EDITED is that size ok now mr mod? i wasnt online to resize it when you asked but cheers for seeing that simple logic and deleting it anyway
