I track my built 26 regularly and always used to fill the catch can cos I'd rev the shit out of it.
Now I've learnt to keep it below 8K rpm and can do a whole day with out touching the can.
Motor is pretty basic, standard sump with Tomei baffle, N1 pump, oil restrictor & enlarged oil returns. Just wish I had of known about putting a sump breather in years ago when it was built.
