Lion Heart Posted November 27 Share Posted November 27 Hi all Could use some help - recently bought a 2017 Ford Explorer Sport 3.5 Turbo Ecoboost, and noticed a strange hiss/rattle noise when you accelerate fairly hard. It is IDENTICAL to the noise shown in this video: [please see 1:25 for demo of the noise] Really useful video, and even gives the part number (YG360), but unfortunately that video is for the older generation (MK4), but he changes out the Check Valve and it fixes it completely. Pretty confident that this replacement would work as the noise is identical. What the MK5 equivalent to his MK4 valve??? Any help very appreciated!
