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><o:p> </o:p></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><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Bob Begani</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>-----Original Message-----</p><p class=MsoNormal>From: Bob Haskell <rchaskell@earthlink.net> </p><p class=MsoNormal>Sent: Monday, April 26, 2021 8:23 PM</p><p class=MsoNormal>To: rfbegani@gmail.com; 'Healey List' <healeys@autox.team.net></p><p class=MsoNormal>Subject: Re: [Healeys] PCV valve installation</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Bob,</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks for the info.
