It is hard to see when faced with a failure of an OS or CCV, but we really have it very good. We don't have to worry about rings and pistons, about valve grinds or valve stem seals. We don't have to replace points, condensors, distributor caps, rotors, vacuum advances, or HT leads. We safely go ridiculously long intervals on scheduled maintenance (remember when it was a good idea to do oil changes every 3000 miles?). We don't replace worn shock absorbers, or brake linings, or exhaust systems every year or so. Water pumps used to be a semi-annual event. Because the rest of the vehicle has become so maintenance free, all we have to talk about is a crankcase ventilation valve (and an occasional vanos system, but for the sake of the example...). So really, a slightly troublesome CCV, which is only a problem for vehicles that don't get hot enough to burn off the condensation, is really a non-issue IMO. These are the best days ever to not have to spend money fixing a car.

/end rant.
