What's wrong with engineers now days?

I can show you plenty of engineering flops "from the old days." Some of them didn't work out so bad simply because there isn't "so much" to a vehicle or other piece of equipment back then.

But stuff like "oil running down a crossmember" is easy. A scrap of sheet metal or even cardboard is often all you need. Back when I had my 69 383RR, later my 70 440-6, I used to use a piece of cardboard under the filter when changing. Easy.
