Okay, so, hear's the deal. Boy genius now has a '94 MB E420. Figured out the coolant leak a bit ago, but there's this other thing going on. The oil pressure guage is pinned. I will gladly entertain any notions some of you may have. First guess is bad sending unit...

Bad sending unit, broken sending unit wire or on the slight chance, the oil pressure relief valve may be stuck shut.
