PCV Valve ?
 

Is it necessary for the PCV Valve from the lower to the upper intake manifold? And could i plug the pressure tube on the throttle body and valve cover tube? i think that is what it is called? please help

The PCV system is very important, why do you want to get rid of it? What mods have already been done?

intake, heads, cam, rockers, clutch, gears, bored, tranny, crank, rods, springs, etc.

Well, you have five choices.

1) Leave it alone (I like this one)
2) Install a blow-by evac set-up (involves welding a tip into your headers, 2 one-way check valves, and hoses from the collectors to the valvecovers)
3) Install breathers on your valve covers (if you have any compression, juice or boost, expect oil all over your engine)
4) Install a valve cover with elevated breathers (works)
5) Blow out your seals and gaskets

Take your pick.

Take care,
