Having problems with your Mercedes-Benz E-Class ?
Replace valve cover gasket on 93 -300E benz and its leaking on passenger side. should I have used gasket sealer and if so what kind ?
No..gasket sealer should never be necessary. Chances are you fit the gasket wrong or didn't tighten the cover enough.
