As soon as the oil runs out.

I can just imagine how fun it'll be to work on an engine with those design features. Probably make a Bristol Hercules radial look maintenance friendly.

I would love to tear down and rebuild something like this.

It's a Porsche, the most likely victim will be your wallet. And possibly your marriage after that.

Pretty brilliant really.

It is. And in Porsche fashion, needlessly complicated yet remarkably brilliant. Also in Porsche fashion, most likely that an oil change is an engine out service.

Interesting. They put extra air intakes at the bottom of the cylinders and in doing so get an extra compression and power stroke before the final exhaust stroke.

Final result: 2:6 power strokes per cycle vs 1:4 power strokes on a traditional 4 stroke engine.

It's an interesting idea but it makes my head spin a little. The video kind of reminds me of a Chrysler video from some years ago regarding developments in heavy duty transmissions.

Issue with getting that to production was the infamous Fetzer valve shortage of 1987.

It was well documented that the number 7 valve was prone to failures.

Our Porsche has been more reliable than my gladiator, by a far margin. Its older, has turbos, crazy suspension, and fast as hell.

I’ve had mine for 11 reliable years. But…never once took it blasting down a desert trail. Different animal for a different mission
