<div dir="ltr">I fitted the modified seal 10 years ago and have always had an oil leak since. After finally removing the gearbox for repair last month I removed flywheel etc to have a look at it. I removed the backing plate and no leaks were identified around the seal, it was totally dry. However the back of the camshaft drain was a different scenario. I then noticed there should have been a gasket according to the books, which mine did not have. I had used a silicone gasket maker in that area and that failed (didn't work). I made a thick 1.6mm (1/16inch) gasket and now think I have solved the leaks problem</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Apr 4, 2021 at 5:14 AM Bob Begani via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</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 lang="EN-US" style="overflow-wrap: break-word;"><div class="gmail-m_-8084671878477982727WordSection1"><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Thanks for all your comments.

Some indicated they still had some leakage. Some indicated oil leakage stopped after installing Positive Crankcase Ventilation. So, I installed a PCV system by attaching a hose to the 1/4-inch opening next to the current 3/8-inch opening used by the brake booster. I had to use ¼-inch fuel rubber tubing attached to the pcv valve at the T on top of the valve cover. As my aluminum valve cover had a side vent, I sealed it off with a piece of rubber. Then I went for a 24-mile ride in traffic and on the highways not exceeding 60 mph just incase and came home. I let the engine run at idle with the fan and electric water pump running for a while and put a sheet of cardboard under the weep hole. While I was doing that there were no oil drops. In addition, I walked my driveway and found no drips. Nevertheless, I placed a can underneath the weep hole overnight. In the morning, I found one drop in the can which could be left over from the previous heavy dripping. I have done this test three times no dripping and no measure loss of oil on the dip stick.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">As soon as I am comfortable with the results, I will take a highway run at 65 -75 plus. Meanwhile, may solve the problem of rear seal oil leakage and, no doubt anywhere else on the engine. Eventually, I will have to pull the trans, clutch etc. to clean the clutch or replace the clutch friction disk as it is slipping due to oil. At that time will look at the new added on seal. <u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Current question is who has no leaks after rebuild with or without PVC system? <u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:14pt;font-family:Arial,sans-serif">Bob Begani <u></u><u></u></span></p></div></div>_______________________________________________<br>
