Just put a PCV valve in mine this afternoon, never even had the hose when I bought it. Couldn't get a cheap one to match the 1/2 inch ID tubing needed, so pinched one off my 4K donor car. Used some thin heater hose slipped onto valve to make it a tight fit in the 1/2 inch tubing and clamped it, sits about 1/2 way between rocker cover and inlet manifold.
