Hello, I drive a 2017 fiesta st and currently ran into an issue where there’s a very high pitch, what sounds like spool, sound coming from the engine. Currently at 45k miles, catless, plumback bov, mishimoto intake

I'd check all the boost hoses. Might be a leak.

That’s a new one lol. Glad you found the issue and corrected it. Hopefully doesn’t stink too bad under the hood now
