So these buckets are securely placed over the valve and spring, use a solid pivot in place of the hydraulic lash adjuster, and use a shim to adjust clearance. This shim, is it fixed in place with some kind of retaining clip.
Why is this direct acting lever arm better than having a roller? I understand about the hydraulic lash adjusters, but it seems that the friction of the vavle train would go up without having the rollers. I suppose if the top of the cam lobe were quite wide and relatively low radius of curvature, then the roller could slip on the lobe an close the valve prematurely.
Could you make a good compromise by replacing the hydraulic adjusters with solid adjustible studs?
