Valve Spring Dynamics and Failure

Looks like the valve guide is lose too.

That spring looks like my tummy when i jump hahaha

These spring videos are so pointless... please show us a video of a normal spring that doesn't bounce?? Cause as far as I am concerned thts what spring does

Why no oil for spring cooling? Of course it's going to fai

The inner spring broke earlier in the video, you can see small metal chips flying out from inside the spring. This left the outer spring alone with a damaged internal spring to interfere with the outer springs flex. See the chip at .33 seconds.

What’s happening here

Valvesprings are the most overlooked component in engines.

That size to side is the death of the valve train in the second half of video

6k rpms?
