Hi there,

Pic 1 and 4 have no heat shield, 2 and 3 have heat shields that need to be removed. Clean up all of that crud as well. Shoot brake cleaner on them but don't spray directly into the chamber. Just enough so it soaks those stuck heat shields.

Heat shields can only be used once, clean all of those chambers and don't let any of that junk/dirt fall in. Use some brake cleaner on a cloth (don't spray it in the chamber) and clean it very nicely. Buy new heat shields, clean up nicely and torque to spec.
