    Replacing the rear main seal in my Maserati 4200 (200323, shared with a slew of other cars, 360, 430, 599, 612) wondering if anyone knows for sure whether to lubricate the seal or leave it dry. I'm having a hard time finding conclusive information in any of the workshop manuals for the cars that share this seal, and no one from the suppliers is able to answer if this seal is PTFE which would make it a dry installation. My guess is to lubricate, but would love confirmation before I put the clutch and tranny back in to discover I blew it :)

    Thanks for the help!

    We lubricate with Vaseline when installing them

    Vaseline on inner wall, but dry on rubber outer yes?

    Thank you!

    Greatly appreciated! Went through 5 WSMs that use this part today and was unable to gather a definitive answer. Very helpful thank you.
