89 560 SEL engine oil & leveling system

My 89 560 SEL has developed a very unusual problem. When doing highway driving I lose engine oil and the suspension leveling hydraulic pump starts overflowing creating an oil slick down the entire drivers side of the vehicle. A check of the fluid in the suspension pump indicates that it is engine oil in the pump. Originally, it was the proper hydraulic fluid. Questions: is it possible for engine oil (given a worn seal) to flow from the engine into the pump? How do I determine if the problem is the pump itself or the seal between the pump and the engine driven shaft?

Cool

Would imagine that the seal on the hydraulic pump is the problem!

I agree, replace the seal.
