I have a 02 ford mustang GT with the 4.6. I keep having a hose pinch itself off there is a picture here it the hose with the blue line (not my pic) I have put a new hose on it 4 times and now the new hose lasted 3 days. This is driving me nuts with the hose pinched off it runs great and with the hose new it runs great but when it collapsing it runs so bad. I’ve tried doing an IAC valve and a throttle body cleaning. Bought a PCV valve but it didn’t match up so Im not sure ware it is thought it was this hose but the new one not even close to what’s in it? Some of the people I’ve talked to say the GT dose not have a PCV valve? I've been trying to sell the car for some time but now with this problem I need to fix it before I do.

any help would be great

 

Are you using the factory hose or a generic hose?

PCV to TB hose collapsed, why? - Mustang Forums at StangNet
2001-04 Mustang 4.6L 2V Gt Pcv Valve To Upper Intake Hose

 

Had a factory hose on it to start but we been using 5\8 heater hose just got a piece of 5/8 blue silicone hose but have not put it on yet

 

bend you a metal hose up and just use rubber tips to connect it. hope it helps! used this once on a 351 i had worked for me

 

I put the silicone hose on seems to be working ok. If - no - when it collapse I’m going to put a metal hose inside the rubber hose so it will hold it open and the metal hose can not been seen don’t really want to look at a metal hose since I have started replace all the other hose with the blue silicone hose's, they look so much cleaner than the factory hoses.
