Have you looked on both sides of the engine block below the heads, if
present it will not look like any type of petcock or valve it's just a
threaded plug with a bolt-like head, you may even see some sealer
around it usually reddish in color. As an FYI my factory manuals do
mention the block drain plug for the V6
