Let's say he were to go with option 2 (the rubber / synthetic sealant that comes from a tube).
Would that sealant last 3 years before you had to reseal it again?
If you use the proper sealant (Oil resistant RTV) then it should last forever; My Miata has this factory and the oil pan has been bone dry since 1990 when it was first done.
That being said bmw has the original gasket which has a metal plate with rubber on it (the metal is has thickness) and I would keep it in there just for proper height (bolts/oil pick up/ oil level sensor etc)

an aside: its too bad the correct/factory part is flawed and almost certainly going to leak as we all have or are going to have this problem
I actually did try that; It didn't work. RTV won't stick to an area if its not clean; And there no way to 100% remove the oil unless the pan is removed.
It slowed mine down a bit(I cleaned as much as I could with paint thinner and brake clean) but a year later I just bit the bullet
Wow I’m just reading all of the responses now, thanks for all of the input everyone!!
I’ll be totally honest: for ease of life (I can do stuff at my house, I did the rear sunroof drains cleaning and some other things) but it was a time crunch and I needed it done. I take it to Freeman Motors in Portland, OR and they did it for $1155. Not sure that the OG gasket will hold forever, but I felt it was the way to go. Next day I drove it to Seattle and back and all was well. They included switching out the oil in that price.
I should start another thread as my next project is my faulty CCC and whatever I do I want AUX/Bluetooth To Seattle after oil pan job, hit 175k miles! Car was sold new from BMW Bellevue. Rear drains totally clogged with gunk.
I get confused which engine I have, it’s the older 3.0 as mine is a 2005. Uncle who gave me the car bought it new, I think it’s been leaking since 150k miles maybe? Has 176k now
