Hi

excuse my english, i'm french

I have an audi 100 S4 V8 (ABH motor) and the engine consume too much oil (1 L for 200 km)
The car as 200 000 km !

there is no blue or white smoke.. just a light black smoke on strong acceleration
But there is oil which go out at exhaust....
So i think the oil isn't burned..... i have not yet verified the state of spark plugs ..
i think it is the valve seals...

What do you think of my problem (piston rings ? something else ?)

Thanks
