FE Technical Forum / Valve stem groove
« on: March 01, 2024, 10:23:54 AM »
I'm seeing some grooving on the valve stem.
REV valves and a 600 lbs spring and an Erson roller tip solid roller RV cam. 5 years and 10k mileage.
I'm going to a much lighter spring and a stock rocker and a solid lifter RV cam.![Grin ;D](http://fepower.net/simplemachinesforum/Smileys/default/grin.gif)
Drive it for another 10k and they will be grooved and mushroomed.![Shocked :o](http://fepower.net/simplemachinesforum/Smileys/default/shocked.gif)
