[TR] Removing PCV system from TR4A

Hi,

I'm planning on installing Weber DCOEs on my TR4A.  TerriAnn's page  
has been a huge help on all the technical details, but now I'm  
planning out some of the installation details.  One is what to do  
about the PCV valve/system.

First, I assume that I can't just remove the valve, and run some kind  
of hose/catch tank from the valve cover, or can I?  Looking at the  
design of the valve, it looks like the crankcase gases really only  
come out when they are "pushed" out from the crankcase, and not  
"sucked" out by the manifold vacuum.

Another option is to feed the crankcase into the air cleaners, like  
was done on the TR4.  Again, does this provide much "suction"?

Installing the draft tube really isn't an option, unless someone has  
a trick to remove the plug with the engine still installed.  I did  
think about making up a tube and mounting it in place of the fuel  
pump, but right now I'm planning on keeping the mechanical pump.

So, has anyone "been there, done that" on this?  Or have any other  
ideas?

Thanks,
Darrell
