Pcv and valve cover filter
Alright to start out I apologizes for adding to the many pcv and egr filter question threads out there, but I have literally been on here for hours only to get scraps and pieces of info about this. So again im sorry, any help would greatly be appreciated.
Q#1 Ok first of all what is that line even called on the valve cover (Red filter)?
Q#2 The air filter housing on my weber obviously has a hole for this^^ but I just taped it off. Does it make a difference either way?
Q#3 PCV filter and cap off vacuum line? I read that doing this could possible cause a oil leak somewhere? Right now I have it routed to the EGR brass fitting and adapter that came with the weber. But I was thinking about buying the egr block off plates for both holes and either putting a filter on pcv or routing it over to one of the vacuum lines on the intake manifold.
Q#4 Is there supposed to be an excessive amount of oil coming out of either the pcv or the other mentioned hole on the valve cover? When I installed the pcv filter on my dads 22r it was pretty much soaked with oil within a few weeks. Also on my uncles 22r he has very small amounts of oil around the other mentioned hole, its just bare no filter, he also has a filter on the pcv.
Basically I just want to know, are the filter mods even necessary, and/or are they doing any good or do they just look nice?
Thanks everybody

the tube from the pcv valve should be to full manifold vacuum, a port under the carb not unlike the port to the brake booster.
the port there on the valve cover, above the "Y" in TOYOTA should be from filtered air but not full manifold vacuum, likely a port on the old, stock air cleaner

What??? Even if that first sentence made sense what "gases" are we talking about? Second, how is anything hot and possibly oily considered "fresh" that is supposed to be coming out of the Y hole?

I found this while searching...any input??
It's late right now but I hope I can get a little more input from people in the coming days, especially from first hand experiences. Thanks again.
