My E320 is suffering from the notorious oil leak at the front passenger side of the cylinder head. I've read that the leak probably originates at the upper timing cover but ends up requiring a head gasket job to correct it properly.

Has anyone tried simply retorquing the cylinder head bolts first to see if it rectifies the leak? After all, I'd hate to fork out the cash for a head gasket replacement if re-tightening the head bolts would suffice. Comments welcome.
