Engine/Transmission (1998.5 - 2002) Pinion seal leak revisited

[John Berger]

Well it seems as though the leak is gone. Just an indication of sweating, which I can live with. I pulled the vent hose and while it was not blocked, I had a hard time getting the cap to release or close down unless I pushed air through it using my compressor. Blowing air through it by mouth did not work. Is there any type of maintenance that should be performed on that cap? Should it be replaced on any type of schedule? I noticed the leak after towing. It did not stop while not towing until I blew the hose with the compressor. I'm just wondering if that cap sticks after a time.
