my 1995 mercedes benz s420 has a oil leak on the front right side of the engine

What is your question?

i replaced the both valve cover gaskets i check the oil pressure sending unit it was not leaking. I DONT KNOW WHERE THE LEAK IS COMING FROM IT LEAKS WHEN I TURN THE CAR OFF AFTER IT HAS RAN FOR A WHILE. ALTERNATER SMALL WIRE ALSO HAS BURT OUT.
