Should be the same for 2003, 2004, 2005, 2006, and 2007 V6 3.0L engines in the Accord. Some people say inspect, and clean or replace as required. Others say replace every xx years/miles as a part of routine maintenance. I'll replace mine every 2 years when I do the brake fluid flush.
If your engine is losing oil and its not dripping out, it could be a faulty PCV valve; oil is getting past the valve and being sucked into the air intake and burned in the engine.
