We cut open a valve cover and ran the engine!! IT WAS SO COOL!!!!
For a while now, we think we have been hearing a tapping valve when our engine is running, but we’ve never heard a tapping valve before, so we’re not really sure! We try a few methods to find it, and end up cutting open a spare valve cover to see if we can find the problem (if there really is a problem).
See the video of me cutting open and painting the spare valve cover for free on my Patreon.
As always, special thanks go to Jerry Kratz and John Howard for all of your help and advice!
