oil injector vac line
 

I was in the process of replacing my oil OMP hoses. After getting everything off I went to take the vac lines off the oil incectors. On one of the injectors when I moved the vac lline the nipple on the oil injector itself would slide around as I rotated the vac line. Could this be my vac leak and can this be fixed or do I need a new oil injector. Could I just put some rtv around it to seal it up?

O well while im at it also how could I clean the atomizers for the primary injectors. When I took off the primary injectors some junk from block fell in there.
