Tony Martyr Posted October 6, 2003 Share Posted October 6, 2003 Where does one find sub-1 litre sized catch tanks for oil? I have decided that the French mineral water bottle and duct tape lash up has to be replaced The D_tweeks catalogue only has 1.5 litre aluminium devices - nice but too big and expensive as the most my k series engine has ever vomitted out is about 300ml I'm sure I have seen plastic bottles with proper caps containing 1.2 inch connectors and breathers on other cars - where did they come from?

warrent Posted October 6, 2003 Share Posted October 6, 2003 Caterham supply a windscreen washer bottle and clamp for this purpose. You have to drill 2 holes, but works well! Have seen a coke can used aswell Phil. Link to comment Share on other sites More sharing options...
Peter Carmichael Posted October 6, 2003 Share Posted October 6, 2003 Chelspeed will be along in a bit to explain that he has a job lot in his garage that will be ready for use just after he has drained thier previous contents. The manufacturer is I believe "Stella Artois"... Link to comment Share on other sites More sharing options...

Pierre Gillet Posted October 7, 2003 Share Posted October 7, 2003 Why a catch tank either than releasing naughty vapors in the air? Pierre Link to comment Share on other sites More sharing options...
Leadership Team Mcalvert Posted October 7, 2003 Leadership Team Share Posted October 7, 2003 Pierre - It's a requirement for doing L7club track days over here. Having seen how much oil my old X-flow used to use before the re-build, I would not have wanted to be following me without a catch tank! Mark - beware, Autocross is moving from Bracknell to Wokingham (In fact, may already have done so). I believe that their new address is: Cedar House Eastheath Avenue Wokingham RG4 12PR.

Pierre Gillet Posted October 7, 2003 Share Posted October 7, 2003 Thanks Michael. And for a normal, non spitting 1.6 K, would it be necessary too? Does the fact that the motor is breathing an improved mixture of air and fuel, make it perform better?

Peter Carmichael Posted October 7, 2003 Share Posted October 7, 2003 Normal K-series installations recycle the crank fumes into the inlet tract. This is good for emissions, but bad for detonation. A standard tune of engine seems to cope, but anything tuned adn used on track probably benefits from a catch tank implementation. Dry sump implementations vent externally anyway, so need a catch tank. Link to comment Share on other sites More sharing options...
Pierre Gillet Posted October 8, 2003 Share Posted October 8, 2003 Humm, would it be worth trying in combination with a 52 mm throttle ? Pierre Link to comment Share on other sites More sharing options...
Robster Posted October 8, 2003 Share Posted October 8, 2003 My Xflow has a dry sump tank, this has a vent to the atmosphere, but of course, as the vent is right at the top of the tank, it can't blow oil out. Does this still have to be vented into a catch tank for use in Hill Climbing/Sprints?? I am sure that the 'blue' book says something about venting, but I don't have mine yet. Would I also need a battery isolator switch? Link to comment Share on other sites More sharing options...
oilyhands Posted October 8, 2003 Share Posted October 8, 2003 Rally design do a good low cost ally tank with sight level and drain plug, you could use this in conjunction with a feed back into the plenum/manifold and use the tank to condense and fluids.

Pierre Gillet Posted October 8, 2003 Share Posted October 8, 2003 Oily, excuse my poor understanding of the English laguage , but what do you mean by " ...in conjunction with a feed back...". My plan was to connect the two hoses between head cover and plenum to the catch tank... Pierre Link to comment Share on other sites More sharing options...
oilyhands Posted October 8, 2003 Share Posted October 8, 2003 The catch tank has to deal with a lot of blowby gas as well as oil vapour and should therefore have an exit for the gases to leave the tank , if you dont do this the crankcase and tank will just pressurize. The feed-back mentioned is simply a vent from the tank to recylce the blowby gas to the plenum after any oil has condensed into the tank. oily Link to comment Share on other sites More sharing options...
