They're the little rubber seals that go on the top of the valve guides and ride on the valve stems.

Mitsubishi engines with over 100k roughly that start having these symptoms are almost always valve seals. I replaced them on 3 cars and it has fixed the smoking from all 3. "my tsi, a '95awd, and a '94 V6 diamante"
