Hardly anything Flow. It doesn't smoke and I don't need to top the oil between services. So I'm thinking it can only be a relatively small amount if the level isn't dropping on the dipstick?Hey Dman have you checked to see how much oil it goes through in between services?
What a lot of you blokes don't realise is that the car is tuned to cope with oil vapours as part of the emission control system, Fair enough if the car has a serious problem with piston blowby but I wouldn't put a catch can on for the sake of it. I can tell you now it will not stop gas reversion from valve overlap depositing carbon gunk on the back of the valves. The only thing you can do there is use fuel additive cleaner from the start of owning the car.

Yeah, It will be bugger all oil if it's not dropping on the dip stick. I just don't get the need for it on a relatively new car, you might want to put one as a preventive maintenance for the future.Hardly anything Flow.

All piston driven motors have a certain degree of blow-by gases, it's just on diesels you get more ( Higher compression ratios) and by adding forced induction you get even more again. As diesels get older, you get what's called 'bell mouthing' in the top of the cylinder bores and the efficiency of the piston rings to seal against the cylinder bores fall. I've also seen where people have used the wrong grade oil, it glazed the bores and they ended up with oil usage and lower compression rations.Modern common rail diesels produce blowby from day 1 and it isn't because the rings are munted. I bought a Provent copy and it was shit, capacity was smaller, filters weren't interchangeable and the original filter medium was shit. As long as you plumb the catch can back into the ontake it is legal. Keep an eye on oil levels and drain regularly.
Thanks Flow. At this stage I'll just keep an eye on things then.All piston driven motors have a certain degree of blow-by gases, it's just on diesels you get more ( Higher compression ratios) and by adding forced induction you get even more again.

Jeez, call yourself a car nut and don’t recognise a factory PCV oil separator system...? Tut tut.Can you please confirm which bit is nice?
Think we have a different idea of what constitutes highly boosted, 400+bhp from 2.8L is normal and I am looking for more....
Avatar gives it away. Tune and highflow cat.Whatcha running, Dale?
Does that steel pipe join to the tappet cover ?All this catch can talk reminded me the Alfa really needs one... It’s a very highly boosted engine (170bhp from a 1.4).
Popped the engine cover off and staring back at me is a factory oil separator that just drains back into the valve cover! Nice
My mate has one of those and close to that figure normally aspirated, I think you might know him (Pierz)Can you please confirm which bit is nice?
