It may not be the issue with my 2019 Scat Pack, I have yet to check... But I started experiencing a vacuum leak recently. When you mentioned that the EVAP hose runs to the bottom rear of the engine, I was very surprised. You see... when my engine gets to running temperature, I start to feel a very light and rapid rumbling (almost like someone frantically gulping for air at 2x speed) around the pedals. When the engine is cold, it briefly runs as it should... But as it warms, the idle becomes rough, and the RPM drop from 1K to 900. I'll update this if I can actually remember to...

Yo. I have a 2022 Scatpack widebody, with under 8k miles. I've been getting a squealing noise (just like you hear from bad belts or pulleys), only occasional, and only at full operating temp (oil 219 to 221 degrees). And it only does it at stop lights or idle, most the time for just 3 seconds or so. Here and there it will squeal or whistle loudly continuously until i start moving again. Brought into Dodge, and tech said 100% was the harmonic balancer 😂 and replaced it and did a coolant flush. Nooo. I picked up, noise was still there. Now they think it's the PCV valve. I'm no mechanic, and although it sorta sounds like a vacuum leak or some air leak, I don't know why it would do it sporadically, and only at idle, and only at full operating temp. Nonetheless, I'll let them replace it, because he's "100%" sure again. I'll update you if you'd like.

Not that it matters but you installed it backwards
