[s-cars] Plugging Up orifices (orifici?)

[manuelsanchez at starpower.net]

S-heads,

Easy now, it's not what Pizzo is thinking.

I'd like to test my intake tract (of the car) for boost leaks.
I have STFA and have found mention of disconnecting and
plugging the hose that connects to the intake manifold and the
idle control valve (the y shaped end).  

Is there another hose that needs to be plugged? I may have
heard of a small line that runs into the valve cover on the
turbo side, does this need to be plugged?

Should I place the the PVC endcap with NPT fitting or schrader
valve assembly into the hose leading from the cold pressure
side of the turbo or from the junction of the MAF and the
large low pressure line that feeds the coldside of the turbo?

Thanks.
