This is a tough one! One of two Gen 5 crate motors 1994's is losing one quart of oil ever two running hours. It is not in the bilge and not apparently burning oil. The oil cooler was just leak tested on both sides, no leakage.
Is there any way oil can get into the cooling water and dumped overboard? Has anyone got any ideas? The problem has been getting worse over time.
Thanks for any suggestions. John B
