3000gt sl smoking when revving up to pull out but
doesn't smoke when under load or accelerating? I
would think it might be valves or valve stems but it
doesn't do it under load any suggestions?

Blue smoke at idle is worn valve guide seals. If the smoke goes away when driving it's the valve guide seals. Occasionally it may be a faulty PCV (Positive Crankcase Ventilation) system. But not that often. HTH. -Jim
