then that would be the shaft for the TPV in the valvebody. thats not good.

maybe it was not down all the way on the D-flat of the shaft. I had a loose one work itself up off the flat till it seemed striped/broke then fell of the stud.

if the e-clip and washer come off the shaft it could have slide down into the pan area. pan R&R needed either way.

got your PM, i get a couple lever scratch up tonight, just in case I look at those old valvebody cores in the bucket for a shaft.
