Pishta is 100% correct. I'm retired supervisor for a large crane manufacturer. Sat in a meeting one day with a room full of engineers. I asked them how many did their own mechanical work on their cars, and cursed the guy that designed the stupidity of where something was placed or what had to be removed for a simple job. Quite a few. Then why not make things simple here, instead of removing the engine to replace the starter, or raising the engine to replace oil filter. The reply was basically each worked on their own specific area and didn't correspond with the next guy in line to see figment or workability. Each in their own little world. Job security.
