WARNING TO THE WISE: NEVER NEVER use silcone to seal valve cover gaskets. Most people put it on too heavy and bits and pieces come off on the inside and go down into your oil sump. I had a VW diesel that a guy brought to me with a weird problem. The oil pressure FELL when he revved the engine and went UP when he let it idle. After removing the oil pan I found the oil pump intake screen was almost completely plugged with bits of silicone from a valve cover job. The suction of the oil into the pump held the particles onto the screen and nearly ruined the engine. Took almost 2 months for the silicone to break off and make it's way to the pump screen. PROPERLY TORQUED VALVE COVER GASKETS IN GOOD CONDITION DO NOT NEED SILICONE!!
