Oil Pan Gasket Replacement- What Else to do?



The oil pan gasket on our 2007 335i auto with 79K miles has started to leak. It's now at the point where it leaks 3-4 drops of oil per day, so it's time to bite the bullet and replace it.

Right now my parts to buy list includes a new oil pan gasket, replacement bolts and a new oil level sensor o-ring. Given the cars mileage and age is there anything else I should tackle as long as I've got the subframe dropped?

Also, has anyone also used RTV along with a new oil pan gasket? Thanks in advance for your input. If yes the blue or black stuff?
