This is a looping animation of a V-8 engine. The firing order is correct, the valves open and close at the right time, the lifters follow the cam nicely, and the valve springs even deform correctly! The block is invisible so you can see all the action. I’m quite proud of it.
Much of this was done with constraints. The only parts that have their own IPOs are the crank, camshaft, and lifters. Everything else is constrained to them in one way or another. I could have constrained the lifters to the cam, but couldn’t find a really accurate way to do it.

When I was a kid, I built the Visible V-8 model, and loved it. I guess I just never grew up…
