I currently have my cusco can piped between the pcv valve and intake manifold, as I have done on all other Hondas I've fitted em to etc.

Doesnt seem to catch anything on my S though, good or bad?

 

I found this thread to have all the information required on catch can/plumbing Catch can plumbing stuff thread

 

Mine and coolchrisuk's (both Cusco) are connected as follows:

PCV to catch can
Catch can to inlet manifold
Mini filter connected to engine breather
Air intake capped off

If I remember, I'll post a photo later.

Mine doesn't collect much, although Chris's collected ALOT on a trackday.

 

As the valve cover is baffled internally in quite a cleaver manner you'll find that not much oil does collect. If you drive hard for long periods or run a boosted application you will find this amount does increase a little.

 

Oil collects on the baffle though, providing a source of oil for suction into the inlet manifold
