Hey Scotty, Have you seen lawnmower and other small engines that have plastic camshafts/gear? I've seen people take apart modern Briggs&Straton engines and even honda GCV engines that are filled with plastic. Sad to see, How long do you think it will be before they try this out in regular car engines?

Well I know in the 70s many automakers were trying to go with plastic on the cam timing chain gears. Seen a few of those go bad.

Are you Scotty

Yes, everything is so freaking cheap these days. Now decades ago ford made an experimental pinto engine out of plastic, but it fell apart during testing
