I've been fortunate over the last 20 years or so. I've only had one instance with a solid rollar application that almost led to issues... I broke the inner coil on a dual valve spring and limped home.

We have always run adequate spring pressure, checked the pressure and the valve lash once a year. Keeping in mind my application is a limited street, use hobby car application. NOT a dalily driver !

Again. You lose enough spring pressure and the lifter loses contact on the lobe as the valve closes, if this the situation after time the springs will further deteriorate to the point it can cause issues other than nosing over at rpm. When people call it 'valve float', more often than not this is what happens.

Gentlemen, remember a solid roller lifter on a hydraulic roller lobe IS IN FACT a solid roller cam application !
