<div class="yiv4116752417gmail_default" style="color:#3333ff;">How does the presence of such a pipe affect the design of a PCV system such as that illustrated--must it be blocked off in order to create the vacuum sought?</div>

<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 clear="none"></div>

<div class="yiv4116752417MsoNormal">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. </div>
<div class="yiv4116752417MsoNormal"><u></u> <u></u></div>
<div class="yiv4116752417MsoNormal">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.</div>
