I have an Oil leak Cobalt Mailbu G5
GM reports that an oil leak that appears to be coming from behind the starter motor is actually coming from a leaking oil pressure switch. The leak appears on 2.2L 4-cylinder engines made prior to 2/19/07. GM has issued a new part that holds up better. Replace the switch and clean up the old oil.
