Hi All,

This SLS system mystery has me baffled. I am gaining oil in the SLS system while losing oil from my crankcase. The oil gained in the SLS is the exact amount that I am losing from the crankcase. How is this possible? I thought there was no connection between these systems.

No, I am not losing excess oil by burning it or dropping it on the highway. The oil
in the SLS system highly resembles engine oil, and not hydraulic fluid.

Any ideas? Its a 82 300TD Wagon.
