Watching an episode of Chasing Classic Cars - so they’re restoring a 1973 BMW 3.0 CSi for a customer. Trying to chase down a damp sunroof liner, they suspected one of the drainage outlets was blocked. So BMW with their crazy German engineering, the sunroof drains out the rear of the side BMW badging on the C-pillars!
Made me wonder what sort of other obscure engineering details that most of us have missed in cars?
The oil filler door is specifically marked “oil” and has a passenger door push rod rather than the fuel pull on the dash to the left of the column.
The driver would have to try to fill with fuel.
I believe the actual reason why Porsche changed is because the oil filler required a different quarter stamping, with a more convolute filler stamping welded to it, along with a cast lid. It was more expensive at a time when Porsche was investing in reduced production costs.
