Just joined. Have a 2008 gxp. This may sound stupid but how does one go about removing the pcv valve tubing and pcv valve from the tubing. Have tried pulling twisting etc. with no luck, so what is the secret to get these to release for removal and replacement. The vale mounting on the cold air intake tube to the turbo was broken when I purchased the vehicle, put temp. fix with super glue and rubberized tape to seal. I would like to remove the whole system to replace or vent to atmosphere. Thanks for any input.
