If you're sure it's not an exhaust leak then rod bearing would be my first guess. Not uncommon on 02's that are running 5w30 oil too. For desert use, the manual suggests a thicker oil (assuming it's really hot) like a 10w40.

"Oil Up to date" doesn't tell me you pulled out the dipstick and checked the level.
