Talked to a local diesel mechanic about our oil leak and have an appointment to take the Dutch Star to his shop Tuesday morning. He'll have to steam clean the underside of the engine in order to see where the damage is.
I called my insurance and there's a good chance the cost of repair will be covered. An adjuster will be going to the mechanic's shop to check out the damage.
In the mean time, the Dutch Star is sitting in the driveway with a pan under the drip while we unload everything.
