<html><body>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?

<div dir="ltr">
<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></div>

<p class="MsoNormal">The V in PCV is for ventilation. There should
be a way for fresh air to get into the engine. In addition to
creating a slight vacuum inside the engine ideally the blow by
gases that accumulate in the bottom of the block and contaminate
the engine oil should be replaced with clear air.</p>

<p class="MsoNormal">Bob:</p>
<p class="MsoNormal"> </p>
<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>
