Sr20de RR valve shims
When i was unassembling my motor we flipped the motor upside down and 12 of my shims fell out and i managed to find 8 so that means i need 4 more shims so how to i go about in putting them back in? Idk which one goes where? Can i just measure the old ones and buy the size i need for my new 4 shims i need?
