2015Edge2015 Report post Posted April 29 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. Share this post Link to post Share on other sites
