Draining both drives today so that service can come and pressure/vacuum test them. I ordered the test pro actively, lube monitors were clean and didn’t drop. Port drained nice and blue, perfect, no concerns. Starboard definitely has moisture in it. It’s barely 40 in here so it’s a little thick. Here is the kicker though, the top air/drain screw plug on the drive was loose. Zero effort to back it out, in fact with little effort I could screw it in 1/8 turn. I distinctly remember torquing on these screws in the spring so I’m baffled as to how it was loose. New high perform lube and new blue drain screw washers in the spring.
Given the loose screw, if the vacuum/pressure test comes back good I’m thinking i am good?
Thoughts? Bottom screw had almost no metal shavings, just the normal trace amount, no concern.
