Does the shim come out if the engine can be spin until the rocker arm is at its highest point ? (This is just checking if the arm is not bent or anything)
If not , show me a video (upload to youtube => mark as “unlisted” , so it’s only found on this forum , get the share link) or a picture upload here.
If the engine you say sounds fine when it is running with no issues , i suspect there should be nothing stuck.
