my Camry's engine, particularly the intake manifold and the spark plug area is dirty. its filled with engine composites. Had an fuel injector service done and thought that would have cleaned it up a little but its still crusty.

have any ideas on how to clean it up? is it normal?

Simple Green. Don't buy the diluted stuff at grocery stores though.

Goto Home Depot, Sams Club, or Costco and pick up a gallon jug of it.

You'll also need a spray bottle and a brush (old toothbrush works good) to scrub the crusted on stuff.
