Ran Daytona August 2022. Car ran flawlessly, and no leaks. Sits in my garage a month or so, and observe this weeping. I first thought that this was a front seal on my Hewland, and I recently realized that on my last engine oil changed, I switched to a different oil, and this is most probably engine oil leaking from the input shaft tube # 17, which closely resembles Redline Gear Lube. Question: Since it is only leaking from the rear, or Hewland side of the tube, can that o-ring be replaced without removing the adaptor from the engine?
