Thanks for heads up!Decided to change the PCV valve on my '05 Pilot. Loosened the one bolt holding it in and it would not come out. I tried to wiggle it and turn to get it out with no luck. I slipped a small flat screwdriver blade behind the housing and the end cracked off leaving the rest inside the engine.
After some messing with it, I found that a 7/16-14 (not even sure why I had this size) tap fit perfectly into the exposed hole. I was able to thread the tap into the plastic housing and then use a pair of pliers to pry against the engine to pull it out. Crisis solved.
A 7/16 bolt would fit in there as well but wouldn't thread in as easy as a tap does.
I just wanted to post this in case this happens to anyone else.
