I think I have the same problem. My '96 EB 4x4 developed an oil leak. The shop I took it to said it was the timing cover gasket that was leaking both oil and coolent.
They said that they would need to pull the motor to replace the gasket and the oil pan gasket. Cost: $1240.00

It sounds like a BIG project. Please post your results if you figure it out.
