welp during one of the lash adj i either stripped the adjuster screw or locking nut, made the novice mistake of going straight for the 3/8" torque wrench instead of hand tightening first (14ft/lb)
tried to rethread the nut (it was stripped pretty clean) to m8x1.25 but still not locking
will get a new locking nut and hope it's just that and not the screw (looks okay on visual inspection) as replacing it means taking off the cams
