I assume this is hard to do?

I am not sure. STI engineers didn't mention how they attach the vertical baffle in place. From the graph, it blocks the oil from flowing around the oil pickup tube section in the timing chain cover area.

, while the video claim the engine might have already failed before the flaps fall off. But it is a fact the flaps failed). We also see even without a complex baffle, a larger oil pan itself will improve oil starvation situation dramatically. It would be hard to argue the performance gain from a falling trap door out weight the risk of engine blow up when trap door falls. I would say hypothetically if I buy your large oil pan, I would definitely remove all the rubber flap trap doors if they present. |

One more reason not to have rubber flaps (or rubber anything) near hot engine oil :-)
(Generally interesting video for the mechanically inclined...) |

There's already plenty of rubber parts that undergo mechanical and thermal stress in your car joints for example. That said, I do understand why people can have concerns.

I know that the Lotus Evora came with flaps in the oil pan in the GT variant, and potentially late in the 400 variant as well. They are a maintenance item with a short interval (2 years) and people claim they become brittle and break quite quickly (i.e. it's not an exaggerated interval). Perhaps a bigger OEM could design a baffle flap system that doesn't need frequent servicing. Does any other cars come with them from the factory? I couldn't find any in a quick search (even for cars that I would expect to have them like a 911 GT3) - most hits are for aftermarket oil pans. I can imagine them moving to dry-sump instead, so perhaps flaps are a niche solution.
