Don't neglect timing belt service, also. Recommended change interval is 60K miles, although it's 100K in CA, for some weird reason (at least on later models).

Make sure the bolt that holds the main pulley, a.k.a. harmonic balancer has been changed to the current style. You can search for topic threads on here concerning this.

My view on oil leaks/burning is this: oil is cheap. Maybe that's why two of mine leak oil and I don't really care too much. Just don't park in friend's driveways if it drips.

Keep an eye out for disappearing coolant, too. The V-6's have a pipe that runs from the water pump, between the "V" of the cylinders that sometimes goes bad and leaks.

If your turn signals cease to function, suspect the hazard light switch.

Welcome. You made the right call, and hopefully you will get to pull a broken-down Defender out of trouble some day.
