I've just made a simple catch tank for the oil vent. It wasn't easy, I'm getting it chromed tomorrow. How do other builders make/buy theirs. The 'Watson' bloke in the mag said " i made up a catch tank and painted. It took me a good 3 or 4 hours....and I've got access to a fully kitted workshop !

there was some ali ones on ebay not so long ago, approx £40 IIRC.
My father has just bought one from Burtons for about £60 (2 litre).

Is it right that if you want to go on track days you have to have one fitted? I was told this but then thought that loads of people take standard road cars out so maybe not true.

For the Westfield racer I work on we made our catcher tank by running a bit of hose into an evian bottle cable tied to the chassis. After a race we just cut it loose, tip the oil back in and reattach it. Simple

After I had made it, I did start thinking that I could make use of some other container..... baked bean tin etc. Might have a go at a more interesting shape next time.

Rally design do a cheap plastic catch tank that has a K&N style filter on top

I know that most (if not all) race formulas have to hav a catch tank, I would imagine it is an aim to reduce the amount of oil and other contaminants which would make it slippery. Even road engines which breathe into the intake would lay oil onto the surface over time.

I don't see whats wrong with an old beer can as a catch tank!

For racing you will need one, for track days they don't check and would never know whether you had one or not. Any container will do as long as it's easy to empty.

Please fit a catch tank if you are going on a track day. I for one don't want to be sliding on your oil! TBH, it is good practise for road use too, if only to try and keep motorcyclists upright...

Also, plastic bottles etc are no good for catch tanks, unless they can stand a bit of heat. The Volvic water bottle I used for a catch tank actually melted, so now an old thinners tin does the job...

I gave macspeedy a old fire extinguisher that had been used ( the cost of a new one was less than a refill) This ali one got a new top turned for it and the bracket got mounted on the bulkhead. We got some T-cut and cleaned all the silk screened Fire instructions off and it looks good. Like it was made for the job.

This is a money saveing of from mac s!LOL

msa also say catch tanks cannot be vented direct to atmosphere and should have one of the little breather filters due to the oil vapor being able to escape.
btw it's a rule for race tracks not for trackdays.
