The slipping clutch is another symptom. As others have pointed out there should be two seals on the crankshaft, the original reverse scroll and the new secondary oil seal, not likely oil in the volumes you are seeing is getting past both seals. I recently installed the square type secondary oil seal which does require machining the back plate. The engine shop was very concerned about not removeing too much material from the bottom of the seal area as this could create a passage to the crankcase. Attached is the before machining picture.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There is also a drain tube on the last bearing cap to help move oil away from the rear of the engine. If this was left off on the recent rebuild it could be a contributing factor.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>One possible check would be to drop the oil pan and see if the drain tube is there and there is a gap into the bell housing.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Harold<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:jpaynepbr@cox.net">jpaynepbr@cox.net</a><br><b>Sent: </b>Friday, March 26, 2021 3:42 PM<br><b>To: </b><a href="mailto:healeydoc@gmail.com">David Nock</a>; <a href="mailto:rfbegani@gmail.com">rfbegani@gmail.com</a>; <a href="mailto:healeys@autox.team.net">Healeys</a><br><b>Subject: </b>Re: [Healeys] 6-cylinder Rear Crankshaft Oil Seal Conversion Kit</p></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Is it possible that is the flex line going to the oil pressure gauge that has failed and it is simply running down?

I am confident he did a good job drilling and tapping holes etc. I had hoped that I would not have rear crankshaft oil leaks. In the past year I have driven the car a little over 1,000 miles 25 miles at I time and recently noticed those infamous oil spots on the driveway. Today I visited my British Car friends at Tech Central in Bonita Springs a 100-mile round trip on I-75 nonstop at 65-75 mph. Fortunately, I carried 2.5 quarts of oil because I had to use it to fill the crankcase when I got there and had to add 2.5 quarts when I got home. In addition, I notice the clutch slipping in 4<sup>th</sup> gear in overdrive if I accelerated. No doubt caused by oil on surface of the friction plate.</span><o:p></o:p></p><p class=MsoNormal><span style='color:black'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif;color:black'>When I got home the weep hole in the transmission bell housing was producing one oil drop every three seconds and when running the engine at fast idle one drop of oil every second.</span><o:p></o:p></p><p class=MsoNormal><span style='color:black'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif;color:black'>Has anyone had a failure using this seal conversion kit?</span><o:p></o:p></p><p class=MsoNormal><span style='color:black'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:14.0pt;font-family:"Arial",sans-serif;color:black'>Bob Begani</span><o:p></o:p></p><p class=MsoNormal><span style='color:black'> </span><o:p></o:p></p><p class=MsoNormal><span style='color:black'> </span><o:p></o:p></p><p class=MsoNormal align=center style='text-align:center'><span style='font-size:12.0pt;color:black'><img border=0 width=708 height=2 style='width:7.375in;height:.0208in' id="Horizontal_x0020_Line_x0020_1" src="cid:image002.png@01D7225B.52A78E80"></span><span style='font-size:12.0pt;color:black'><o:p></o:p></span></p></div></div></div><p class=MsoNormal style='margin-bottom:12.0pt'><span style='font-size:12.0pt;color:black'>_______________________________________________<br>Support Team.Net <a href="http://www.team.net/donate.html"><span style='color:#0563C1'>http://www.team.net/donate.html</span></a><br>Suggested annual donation $12.75<br><br>Archive: <a href="http://www.team.net/pipermail/healeys"><span style='color:#0563C1'>http://www.team.net/pipermail/healeys</span></a> <a href="http://autox.team.net/archive"><span style='color:#0563C1'>http://autox.team.net/archive</span></a><br><br><a href="mailto:Healeys@autox.team.net"><span style='color:#0563C1'>Healeys@autox.team.net</span></a><br><a href="http://autox.team.net/mailman/listinfo/healeys"><span style='color:#0563C1'>http://autox.team.net/mailman/listinfo/healeys</span></a><br><br>Unsubscribe/Manage: <a href="http://autox.team.net/mailman/options/healeys/healeydoc@gmail.com"><span style='color:#0563C1'>http://autox.team.net/mailman/options/healeys/healeydoc@gmail.com</span></a></span><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
