So the 2020 is nearly leak free at this point. However, the tach cable where it enters the housing near the oil pressure sensor leaks, not real bad, but bad enough, better than it was. When I last had it off, I used some Permatex Ultra Black (maximum oil resistance) on the threads which I also used with success on the oil pan gasket, but it's still leaking. Is there any better solution or do I just need to try again. It's in a horrible place to try to tighten properly, even after taking off a lot of the linkages that are in the way.
