My oil pressure has also dropped about 10-15 psi from where it was after the rebuild. Assuming that a fresh engine will have higher oil pressure will that result in higher crankcase pressures which would tend to increase leakage past the scroll seal?</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff">Q2--My car has an early aftermarket valve cover and looks like the ones sold by Ray Juncal minus one fin and with a flat versus a slightly convex top surface. There is no vent nipple and it has a spring-loaded filler cap that probably does not make a tight seal though there is no oil blow-by. Is there a real advantage to installing a PCV valve and if so where should the hose terminate? I removed the original LeMans kit CAB some time back and would prefer not to refit it.</div><div class="gmail_default" style="color:#3333ff"><br></div><div class="gmail_default" style="color:#3333ff">Thanks--Michael Oritt </div><div class="gmail_default" style="color:#3333ff"> <br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Nov 4, 2023 at 4:04 PM Michael Salter <<a href="mailto:michaelsalter@gmail.com">michaelsalter@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">I've fitted a couple of those kits and have been somewhat underwhelmed. <div dir="auto">Firstly you have to be VERY careful with the rear cap machining alignment, definitely a case of measure twice, cut once.

I did mine in my 8" lathe and it's pretty scary having that huge hunk of steel spinning between centers (don't forget to disable the chuck brake ... rather frightening to notice the chuck winding off the spindle as you power it down😳😳).</div><div dir="auto">Finally, after all that effort, there was still a small leak from the rear main which I finally resolved by installing my PCV. </div><div dir="auto"> kit. <a href="https://precisionsportscar.com/austin-healey-100-engine-oil-leak-solution/" target="_blank">https://precisionsportscar.com/austin-healey-100-engine-oil-leak-solution/</a></div><div dir="auto"><br></div><div dir="auto">In future I'm not going to bother with the seal kit and just fot the PCV.</div><div dir="auto"><br></div><div dir="auto">M</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri., Nov. 3, 2023, 11:19 p.m. Michael Oritt, <<a href="mailto:michael.oritt@gmail.com" target="_blank">michael.oritt@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="color:rgb(51,51,255)">I'm having my 100's engine done this winter and though it's not a terrible leaker I''d like to install a rear seal kit to tighten things up as much as possible.<br>I know there are several different kits available and would appreciate any input on which one to select along with installation tips.<br><br>Best--Michael Oritt<br></div></div>
