Question about 2000 Lexus RX 300
This is usually caused by worn valve guides. Do you have a lot of mileage? More than 150K? This condition is not a problem for the engine (though it might be embarrasing) as long as the oil doesn't foul the plugs. If you plan to make this car last a lot longer, it may be a good time to rebuild the engine or at least the heads.
