2011 Ford Fiesta - PCV Oil Separator / Intake Manifold Gaskets Need Replacement

Hey everyone,

I'm not sure if this kind of post is frowned on here or not. Please let me know if it is!

I've got a 2011 Ford Fiesta (manual trans., about 95,000 miles) that recently started randomly stalling out at red lights, stop signs, etc. A few years ago I was experiencing similar symptoms, and I took it to the dealer and they replaced the throttle body, and that seemed to fix it - but just recently it started randomly stalling again.

So yesterday I took it back to the dealer, thinking they would tell me they needed to do the same repair (replace the throttle body), but this time they're saying that it needs to have the PCV oil separator and intake manifold gaskets replaced. They said that "the separator is clogging up, causing the issue," and they're quoting me $1220 for the repair.

What should I do here? Take the car to another mechanic for a second opinion? Suck it up and pay the dealer for the repairs? Or just give up entirely on this crappy old Fiesta and put my money towards a new car?

Any / all advice would be GREATLY appreciated. Thanks so much in advance.
