any ebay oil catch tank but be sure to block the 2 pipes to the inlet up and let the catch tank breath to fresh air if you actually want to to be doing something. Lots of people see it has 2 pipes so connect one in and one back out to the inlet manifold which means all the oil vapour is still getting in there, robbing you of power and sooting up the VIS valves.

all this talk of catch tanks reminded me that i should check mine and empty it, lucky I did!! the drain plug had almost unscrewed itself and was leaking, so people with tha carbon catch tanks check your drain plugs!!!!

That looks fine but the piping that comes with it is no good.
Get some of the black oil/fuel pipe from Halfords
The top of the tank comes off so 4 screws and bobs your uncle.

Dean this catch tank is fine,
it is the exactly same one I have bought from eBay, the piping you get is not so good, also get some proper jubilee clips from Halfords or motor factors and as Paul says you need some decent fuel/oil piping.
The fuel pipe diameter needs to be 9.5 or 10mm to fit.

Me too, don't forget to put some wire wool or kitchen thingys, can't remember what they are called!! Lol inside the catch tank, its those that soak up the oil!!:slap:
It also depends on the oil.
With the motul chrono in now I don't get any oil in the tank. It's one of the reasons I bought the oil was that it has low evaporative emissions and seems to be living up to that claim.

Well I've not got a drop of oil in my catch tank and the performance of the engine was noticably up when I connected it this way. If you look at any decent catch tank installation it does not reconnect to the inlet, its there purely to catch any oil blown off.
Its only on 180's that I have seen people connect it up the wrong way and basically put the air being drawn into the tank back into the inlet. Inlets being connected to the crank case is purely an emissions thing, its not needed for performance and removing this link will net you some decent bhp, epsecially when the engine is hot.

Yes thats the same can I have, I used the 2 inlets one for each crank case breather and then added a 3rd pipe to the top to vent to atmosphere. I blocked the t pipes into the inlet up with some rubber blanks over the ends, cutting them off about an inch from the inlet.
Well I originally fitted a masher catch tank and it did the trick but was way too small.Fitted a full sized one now without any gauze or anything and one pipe in and one pipe out. It seems to work ok. There is this theory that the vapour gets sucked straight back out and another theory that no vapour at all in the inlet could lead to damage to the inlet system through lack of lubrication around the inlet butterflies.

Oil vapur in fuel dilutes the octane rating of the fuel. Any car built for perfomance (or modified for perfoamnce) will have the crank case breath to fresh air. Last thing you want in your charge is hot oil vapuor.
I have heard that the oil might lubricate but cant see it myself, its just not designed well enough to beleive that the oil is needed, if it was then there would be drain chanels etc to run any captures oil into the buterfly hinges.

Good post and i would say even with the baffle in its never going to stop all the oil vapour so if any lubrication is needed its still going to be there.
What you wont have though is large amounts of oil in the throttle body and all that crud that gathers in the bottom of the old air box.
For now or until anyone proves it wrong i will stick with the tried and trusted method.
