Breather related oil leak.

Ever since i started doing trackdays, i've began to get a constant oil leak. The leak isn't bad, but it's got to the point that everytime i park the car, i've got a good square inch of oil leaking...

So far, the only thing i can put it down to is a breather related problem.

I've only got the standard sized breather pipework, that goes from the block.. up to the rocker cover. This is T-peiced and they both go into a catch tank.

Should i need to improve/make this bigger ? i could try doing two seperate larger pipes.. both into the tank ? What's everyone else done on a Twin carb OHC ?

All seals and gaskets are pretty new.

Any ideas where its leaking from ? might just be a leaky gasket rather than a breather prob.

Wheres it leaking from?
Any pics of your setup?
Put the rocker cover outlet straight to the catch tank.

Is it just when you drive it hard then?
Oil getting hooter/thinner? Leaking froma gasket is more likely... mine did that only when I ragges it from the crank seal...
