@LotusElise What would cause this? I have three sets of used lost motion spring here at the house. Since I am installing new cams and new valvesprings , I figure it would be a smart thing to order new ones, all (8) cost $52.00. I have seen these things bending, breaking etc. on both forums, thus I am not going with used ones to play it safe. They are not visable when the valve cover is pulled off, the cams & rockers have to come out ot get a visual.
