2port catch can
 

how do you plumb in a 2port catch can on a classic

you cant (not and it function correctly)

2ports is not enough.. as you need a vent...............

need a nice big port for crank (15mm pipe at least).. needs then two for each cam breather or one Tee'd...
then a vent..

Simon

So your saying throw it in the nearest bin and get a 3 port.
How do others get away fitting 2 ports then? as i have known others to fit a 2port

Numerous turn up for mapping wrongly piped.

Do you have a link to which in it is?

It is possible to weld bosses to it and make it work

A two port will fit however it won't really be effective and may actually cause issues as it will restrict the engine breathing.

As Simon Says, Fit a 3 port minimum port 1 for the Crank case (15mm) and port 2 for the heads (tee'd together) port 3 return to inlet (ideally vta). Personally I'd go 4 a 4 port so the heads aren't tee'd and the final port vta's best I've seen is the one on Simbas car as supplied by Brent at SMD which has 3 inlet ports and a huge VTA port/filter so no restrictions on breathing.

one of these i believe. although i never bought it from there

so there no way of doing it

You could buy a second one, have one for the heads with the two pipes Tee'd together and run a second one for the crankcase. Both VTA
