Ok so here is my problem, I have some grease leaking around the threads where the pressure lubricator screws into the LT shaft, on a GDLT. I cleaned up the grease run it for a lil while and the grease starts to leak out of around the threads. I unscrewed the lubricator from the shaft and pulled the old teflon tape off and put somemore on and screwed it back in and snugged it up a lil and it's still leaking some grease. Anyone got any ideas on how to stop it? Thanks.

Tighten it more

Check is there is a crack in the plastic housing.
the leak may be there an not in the thread.
