oil, vapor separator

[Dspider]

I have the manifold off and noticed that the oil/ vapor separator is open. Should I plug it or leave it open? I'm running a 32/36 Weber with all the vacuum lines plugged.
Thanks ,

Danilo

Depends upon your vehicle inspection requirements and your conscience. You can attach it to the air cleaner where it was originally fitted, or buy a small racing filter to vent it to the atmosphere.

If you mean the long hose that runs from the vapor/oil separator is missing and the port is open, absolutely do not "plug" it. The lower crankcase must be vented to relieve crankcase pressure. Either install a hose with an aftermarket breather (filter) at the end of it or, better still, tie into the base of your carburetor.

Thank you guys,
I will probably fit it to the air cleaner.

i would not suggest running it to a vac line it sucks up oil and drops oil press.
