I changed my primary oil over the weekend and noticed that the dealer had put a little of some sort of sealant on the primary drain plug. I have some Form-a-Gasket pliable sealant. Would this be OK to use?
my .02; HD still uses pipe thread on this plug. pipe threads will let liquid flow in the root of the thread and it will eventually seap out. i use teflon tape. start it about two threads back from the starter thread. be careful when tightening up this plug. HD gives a distance measurement, not a torque value. if you tighten too much, the plug will act like a wedge and put stress on the primary cover and engine housing.
I posted a question a few months ago about stripping the threads out on the plug.......I did and many others have also.....Everyone says no big deal and so far the taflon tape works with no leaks, however the plug doesn't tighten up!
