Hello ladies and gents,

Would anybody know if the 6MT on this engine (same as fiesta trans I think) has a peep-through hole where I can check the clutch assembly in the bell housing? I'm getting some nasty knocking sounds and I think I've narrowed it down to the clutch assembly. The noise seems louder up by the turbo but seeing as driveability was unaffected in my 1500 mile drive back home through the Colorado mountains, I don't think it's turbo related.

Symptoms: Really bad knocking sounds and the engine shakes like crazy but when I clutch-in the noise is gone. Once the RPMs go above 1000rpms, whether cruising or just pressing the gas while at a stop the sound goes away too. Drive-ability seems unaffected but I was in the middle of a roadtrip 1500 miles away from home before the noise started (drove the 1500 miles back without an issue.) Car is currently on stands and nothing looks broken from what I can see. I've had a similar knocking sound, but 10x quieter, since ~30,000 miles but I never thought anything of it since the car drove the same.

No modifications, car has 180,000 miles on it. Heres a link to the video: https://photos.app.goo.gl/AFQH9qnht6rW3DbV7

I would also like to add that I just got an oil change before the trip (~2000miles on oil + filter). Oil is still pretty clear and isn't milky.

Update: Looks like there's a pressure plate recall for my car. Looks like I'm in luck, I'll just bring it in and get a new clutch assembly and hopefully that solves my issue.

Another update:

I finally got my car back from the dealership. The recall only covers a PCM reflash along with a new clutch assembly IF the clutch fails the "slip test". Now we know a clutch slipping can mean half a dozen things between a complete mechanical failure to burning up the friction material; so that's a pretty generic "test." Well, they reprogrammed my PCM but didn't touch the clutch so I told them to look in the bell housing. Long story short they ended up replacing the clutch assembly, put it back together, the noise was still there, so they had to re-drop the trans and replace the TOB and flywheel. I guess a flywheel and TOB isn't part of the "clutch assembly" despite the fact that all those three tend to die together.

The Fiesta had a 5-speed manual with the 1.0L.

The pressure plate was to be inspected since a clutch fracture could break some of the fingers of the pressure plate and puncture the transmission housing. Recall document

Sorry I meant it shares the same trans as the Fiesta ST (I think?)

I thought the flywheel was to be inspected for cracks as that was the point of the recall?
I guess only if it fails the "slip test". Completely stupid IMO though. According to the service adviser, when they replaced the clutch assembly and put it back together the noise was still there so they had to re-drop the trans and replace the TOB and flywheel, all to a tune of $1100 (yea I'm going to be contact ford about that.) They gave me back the factory flywheel at my request and it doesn't look like there's anything wrong with it

On top of that, the PCM reflash now makes the car's power band more linear instead of the diesel-like torque at 2K rpms.
