I remember the PSA pilots referring to them as "four oil leaks connected by an electrical fault." The Lycs were indeed a disaster (at least the early aircraft); the company I worked for had three aircraft and in the space of a year we had 12 engine changes, about half of them inflight failures.
The strange thing then is that, nearly 25 years after they were first delivered, these same ex-PSA airframes are still in everyday service over here in Europe on trunk routes, including a number on the various business services out of London City - an airport where almost all the commercial operations are by various high-wing types such as 146, F50, Dornier 328, Dash-8, etc.
