i know there was a thread that covered this, but because of nico's non existant seatch engine im having a hell of a time finding it

basically i wanted to know what sizes you guys used to tap the holes in the valve cover to use braided lines for oil catch cans and such?

also for the pcv valve

Valve covers are 3/8" npt and the pcv hole is 1/2" npt. I just did this about 3 weeks back. No drilling required on all 3.
