[Vwdiesel] Stuck rings

[Val Christian]

A local kid has a gasser with high oil consumption (1qt/350mi) and bad compression in cyl 1&3.  After hearing the story, I think the rings are carbon/sludged up.  I am wondering if anyone has had luck with the various (chemical) treatments?

For her, a rebuild is probably out of the question. Since the car would get trashed, I'm looking intpo last ditch efforts.
