It is locked ... you need to press in on the side to unlock and at the same time pull it up and off.How do you remove the hose which is over the PCV valve? Simply pulling it off does not do the job. It feels locked into place.
What year is your car and model? I have a 2019 GT and just got a new one at ford they gave me 297 and I didn’t realize till after there is 2 different ones and don’t see part number on my old one.Is there any difference in installing the following 2 PCV valves onto a 2019 Ford Mustang Bullitt, apparently they both fit:
1) EV281 (7L3Z6A666A) 4 small ports, naturally aspirated use based on the list of vehicles
