@@boeing900 It has been locally hardened in the bent area but i doubt that it would exhibit a significantly lower fatigue life if i could have gotten it straight and removed the cyclic bending. Even a perfect valve sees some bending during operation as the valve doesn't always return to the seat with perfect concentricity, so the stem sees minor bending as it centers in the seat during operation. Real question is how much extra bending would i be causing and would that be enough to impact fatigue life meaningfully.
@@carcomp101 I did not. Got it straight but still had some slight runout at the end of the valve. Bought a new valve but that project has been back burner since then.
nice..
lol... Ah no. You may be able to straighten it but you sure don't want to try and reuse it.
Why not
@@MrMickmenPL Thats easy, because now it's weakened

Did you use them or not?
