    I put many miles--well over 100K--on my Nock PCV setup before
    upgrading. There was no sludge at all, and the head looked normal (I
    expected some carbon buildup on the rear cylinders).<br>

      This all sounds good, but I'm concerned about sludge build up...I
      remember my '55 Ford with added rubber plug to the vent &
      adapted PCV and takeoff on air cleaner. Under the rockers was a
      gooey mess after some miles. I kinda like my Type 3 system as
      original on my BJ Healey and the rocker shaft and rockers are
      clean not a sticky mess. Sure it drips some oil from the bell, but
      don't all us oldies drip something? Hank<br>

          <div>I am with Harold on this one. In theory, with substantial
            vacuum holding in the CC you would not move any of the
            accumulated
            gasses and moisture from the CC. Would be interested to hear
            if
            anyone has actually measured the CC vacuum after the
            plugging and
            soldering of all the orifices ? Particularly at idle when
            the
            vacuum is high - what does the PCV valve regulate it to ? My
            car is
            about 17/18 ins Hg at idle. Would also be interesting to
            look for
            oil at the system vacuum inlet pipe after a few miles.<br>

                <p class="MsoNormal">Let me know how your installation
                  works with
                  the hole in the oil fill cap soldered.  No doubt, the
                  rest of
                  the engine is has no breather inlets such as the valve
                  cover? 
                  The reason I ask is I did not solder or seal the oil
                  fill cap and
                  my aluminum valve cover has  a vent on the side into
                  which I
                  stuffed a piece of oiled 3m sanding pad.  The reason
                  was that
                  in the early days of PCV valves on engines the car
                  makers were
                  creating a breather so fresh air could circulate in
                  the engine and
                  some articles indicated it was desirable to keep air
                  flowing to the
                  crankcase. </p>
                <p class="MsoNormal"> </p>
                <p class="MsoNormal">Maybe some of the other listeners
                  who have
                  been using a PVC system sealed could comment on the
                  operation.  Currently on regular 25-mile drives at no
                  more
                  than 60 mph the drips under the bell housing weep hole
                  after the
                  ride are limited to a spot the size of a quarter in
                  the can
                  underneath.  Next time travel on I-75 for 50 miles at
                  higher
                  speeds I will see if the amount of oil increases.  If
                  it does
                  I may seal vent to see what happens.</p>
