Opinions on this are all over the place but there appears to be two types of=
currently used PCV valves, spring by loaded (to keep the plunger on its sea=

the plunger. Orientation is important to the non spring loaded type having t=
he vacuum connection end up. Fir Spring loaded type orientation does not mat=
ter except the vacuum connection needs to be on the end of the valve that do=
es not have the plunger seat. Just a matter of blowing on each end to see wh=
ich way the plunger moves.=20

Attempting to install a PCV valve on our tri-carb engine per
Norm Nock's Tech Tip (page 98). Made an adapter (5/8"-18 to
3/8" barb) that replaces the plug in the front inlet manifold. =
3/8" hose to the PCV valve. Two questions:<br>
<br>
1) Does the PCV valve need to be orientated in a particular
way? Norm's diagram shows it horizontal and I have seen them o=
n
non-Healeys vertical (engine side down).<br>
<br>
2) The valve cover tee is 5/8" diameter, the engine side of the
PCV valve is 1/2". Anyone know of a short hose with different
diameters on each end?<br>
<br>
Thanks.<br>
