2015Edge2015 Posted April 29, 2022 Report Share Posted April 29, 2022 Wondering since I get a slight stumble in idle once in a while and noticed there a good amount of blowback if I removed the district. Enough to spit out fine particles of oil. Makes me wonder since every so and then when I turn off the engine, I get a random very short "honk buzz" noise that comes from the engine bay. It does it 2 times usually. Make me wonder is the pcv is to blame. Quote Link to comment Share on other sites More sharing options...
enigma-2 Posted May 2, 2022 Report Share Posted May 2, 2022 The noise was discussed in this forum. May or may not be your symptom. https://www.fordescape.org/threads/whirring-buzz-sound-after-vehicle-turn-off.54010/ Quote Link to comment Share on other sites More sharing options...
