Catch Tank
Slater - 8/6/09 at 09:05 AM

My breather filter on the cam cover sometimes drips oil, making a mess. So, I'm going to make a catch tank. The choice of bottles is below, I prefer the yellow one.

I can drill a hole in the plastic cap to accept a small breather filter.

My question is what is the best way to secure an inlet pipe into the thin ali bottle? The pipe will either be 15mm copper pipe or a 24mm rubber hose.

I bought a compression fit 10mm inline connector from Whickss..

Drilled an undersized hole in the alloy bottle and simply screwed one side of the connector into the bottle with some silicone to seal/hold it inplace..

Seems to have worked well with no nut on the other side!

The slightly neater solution as done by someone on here (sorry cant remeber your username), was to get some threaded connectors for compressed air... threaded one end and smooth the other.... that and a carefully fiddled nut inside the tank would work too!

I used a SIGG drinks bottle for mine on the Zetec, used a T-piece on the lid.

I cut the screw cap down, drilled a small hole, fed one of ends along the straight inside, and epoxied it into place. Then a filter straight above, and coming in from the side is the oil breather pipe from the rocker cover. Seems to do the job!

Thanks Charlie, I will do the same. How did you secure the SIGG bottle to the car itself?

Homemade clamp could be a strip of ali (with edge strip if you have some to make it look finished. Bend it around the bottle. Where the strap wraps around the back you can pop a bolt through to give the grip. Then the 2 ends can be placed against the panel to be fixed onto and secure with fixings. Or a couple of cable ties?

Sigg bottle was a bit expensive wasnt it Why not try a different flavour vodka, might work better (after you have consumed the contents of course).

I used 2 anodised drinks bottles with the biggest P clips I could find holding them onto the bulkhead. The breather pipes fit over the bottle inlets and I have holes drilled in the sides to fit filters on. The pipe is from a washing machine at the moment!

I'm using a plasctic open-front holder, that I think used to house a plastic toy/ornament. But I was planning to use a bicycle drinks bottle holder initially, found in most bike shops/Halfrauds etc.

Just take the bottle with you and measure up! Locost (but stylish) at its best....

Is a catch tank instead of a breather? Or am I being more stupid than normal?

Yes, its a catch tank. Breather would be the bit on side of engine that allows the crankcase etc to breath. OE tintops breath the crankcase ventilation fumes back into the inlet manifold to be burnt off. On modded carbs where there is an inlet tract for each cylinder (etc) this isnt easy so alternative is to feed the vented spoils to the catch tank and empty it once in a while. As you can see catch tanks can be as locost or as expensive as you fancy. They are rarely on display so locost is great.
