I got my valve cover kit and I got these spacers that are the same thickness as the ones that are on the bolts. Has anyone replaced the ones on the bolts for the new ones? I can only assume that I should replace them. I've watched many videos and no one talks about these spacers. The Toyota dealer says you should buy new bolts. One guy suggest putting two 5/16 washers so you can get the proper torque on the bolts. Oh, my bolts were not on very tight which surprised me.
