The 119 motor oil tube change did not take place at the beginning of the 1994 model year, but earlier. The vast majority of the cars of this era have a 104 motors which do not even have oil tubes. In the bigger picture oil tubes are an infrequent inexpensive and insigificant DIY repair. Anyone wishing to argue that quality declined specifically at the beginning of the 1994 model year should be able to point to mechanical and/or interior part numbers that changed. Both HFM and LH engines and engine management systems were virtually the same in 1994 as in 1993. The very few changes in the era were often enhancements - such as a vastly superior DIY diagnostic system.
