Good advice above.

The system we have built for my track project is a proper oil condenser. This one has been built as a bespoke item with internal pipework to ensure the oil in aerosol suspension from the cam cover breathers is delivered to the bottom of the tank. This ensures the PiperCross filter on the top isn't overwhelmed by oil vapour. There is a drain plug which needs to be checked regularly to ensure there is no build up of oil in the tank.

I think Blitz do a baffled catch tank but I'm not sure it has the internal pipework. A bit of Googling might reveal more info or identify a suitable off-the-shelf design.







I posted a pic of a very similar system on a roadgoing GT-Four recently. It looks nice with the stainless Aeroquip but we decided to standardise on the black woven pressure hose with the track project as it is possible to bend the hose around the bodywork much more easily than Aeroquip. Practicality over looks!

Having started to fit my catch can today I found that when removing the oem unit there are actually 2 hoses that go into it, crankcase breather and a smaller hose that looks like it disappears under the inlet manifold. Whats it for gents?

cheers guys

It is a drain back into the sump. I'm guessing it joins one of the head drain holes.

At least its nothing too important then, was worrying that I wouldnt be able to start the car without it.

Worth leaving the standard catch can IMO as it will take a fair proportion of the oil mist out and return to the engine, reduces the frequency of draining the external can.
