Oil catch can on a 2009 sti advise
Well chaps are they worth fitting ?
Also has anyone fitted one that they can show me best way to fit one as ive watched videos that show pipes being tapped into but then others that say run pipes direct to can and from can dont cut and T off pipes as not all oil will get caught

I have seen a car have some antics on the track and the catch can as overflowed onto the NSF brake, which was not good. If you were to do some enthusiastic driving I would want as much of the oil in the engine and not in a can on the side.

Oil mist from the cam covers and crankcase is directed into the catchcan. If it is directed back into the inlet tract, as per the normal set up, this reduces the octane rating. Steel mesh in the catchcan helps turn the mist to droplets which fall to the bottom of the can. From here they can be reintroduced into the sump. Without the mesh the mist can be vented direct to air, usually under the car alongside the gearbox.

Different companies will make their own filter medium and inlet designs, and some serious performance applications may have baffles inside to prevent any oil in the can from sloshing around and returning through the outlet - how many of the aftermarket are just cans with no baffle or anti slosh with just an inlet and outlet?
IMHO unless the car is seriously being ragged I would question why

I understand that but unless there is a feed from the bottom of the can then the engine is slowly being starved of oil, how many people actually check their normal engine oil?

The oil mist that ends up in the catchcan would have been burned after passing into the inlet tract, so oil losses should not be increased by the use of a catchcan. Having said that I still check the oil level every day before firing the car up, then top up if required (that's not too often as it happens).

Is there any particular reason you want one?

all others (Grimspeed, S2 Industries, tomioka, etc) mount on on top of the oil funnel so RHD/LHD is the same
i dont redirect mine back into inlet either but off into a different overflow bottle
