Then, remove the intake manifold and any components obstructing access to the starter, including the heat shield and electrical connectors. Unbolt the starter from its mounting position and carefully extract it.

My Infiniti dealer wanted $2200 to replace the oil pan. The part costs about $300 and labor costs came in at $1900. You may be able to save some money by buying the part yourself and having an outside shop do the job. My local Nissan dealership said they would do it for $1500.
