Does anyone have experience in adding cleaning ports to the intake manifold by adding threaded inserts into the plastic runner? My thinking is that a very small screw could plug it in between cleanings but still allow direct to valve spray of GDI cleaner of choice. I don't know what kind of insert (heat, glue, expansion etc)( would be appropriate but it would have to be better than a general spray into the intake hose.

I'm open to all comments, good or bad.
