Decided to replace the PCV valve on my Grand Caravan (3.8). What should have been a five minute job turned into a headache. The PCV will turn in the housing, but will not pull out. There is little to no leverage. To top it all off, the end of the valve chewed off. It sits in a housing and is hard to get to. Had to be to work so I just put the hose back over the PCV. Any suggestions on getting it out (special tools?)?
