There are 2 copper washers, 1 fiber washer, & 2 chambers (upper & lower). It's unlikely they're not unstalled, since the lower chamber gives the injected fuel its spray pattern.Yeah between the injector and head. When I squirt some brakecleen down there it coughs and carries on so am guessing they were never replaced/installed.
Also, brake cleaner & starting fluid are not good for diesel engines.
