There is a connector that has OEM O-rings in it, the part and O-rings costs about $10. Also one leak has the oil wicking up a cable and into the car by the passengers feet, that can get expensive to fix. Sometimes a leak gets blown back along the underside of the car and it can take a while to drip.
Sometimes the list of problems is actually a figment of the mechanics imagination, he gets a cut of the prices charged in most dealerships. Independents make their money on fixing your car, not for being good guys.
