I have replaced reservoir and cap because of hairline cracks, the notorious heater core hoses which weren't leaking, The water pump which was weeping, changed the thermostat housing to a metal one, and my car is still losing coolant. Im guessing its a high heat and pressure coolant loss as it was pressure tested by a shop that works on ecoboosts specifically and to no avail I still am losing coolant. No visual dripage so my next guess would be the radiator return line or the radiator or maybe I'm wrong. But the shop basically said that they couldn't find any problems, my car doesnt spew white smoke that would lean toward a cracked head... so not sure what to do at this point.

786 mile trip later! Pretty pleased with the MPG but surely could be higher as it started at about 16 MPG. No issues so far (knock on wood) and I am loving every minute spent in this beauty. Cobb port soon and then let the real fun begin. Also any suggestions on an aftermarket stereo? I have the Sync 1 so I’d like to get a head unit with apple carplay. OEM is a bit too pricy for me. Any trustworthy amazon units out there? Thanks!!

These photos are from my first event, since then I’ve got 2 wins and a 3rd place in class the car handles amazing and autocross has made me appreciate it so much more. here’s some footage from one of my events https://www.youtube.com/watch?v=wr-CeK4atqY

Lights used to show an error when set to auto resulting in the left headlight pointing down to the left. They would work fine beforehand for a few minutes following the steering etc. now the error is happening when they’re just set to on. Sounds like a stuck motor?? Any ideas. All wires inside look intact

What sealant should I use to mate the two halves of the transmission. Had to drop it again for a failed slaved cylinder and might as well seal it again because it has been leaking.

I'm being asked to go back in after having the pcv replaced under a Ford customer satisfaction claim to have the PCM reset I believe. This all revolves around the tank deformation issue. Anyone know if having a tune will be an issue ? And has anyone else had these recalls covered that can tell me what they got for parts and service from it?

3 months after joining the community, my FoST journey was cut short after my petrol MP275 ST was stolen (picture 2). It was a financial hit and a tough first experience of theft, especially given the car was so new to me.

I had to leave this subReddit because it was too painful to see you all modding, driving and enjoying your cars.

😈😈 I had an opportunity to pick up this top spec ST3 and I’m proud to say I’m back in the club.

Sadly, it is the TDCI - it’s still a heap of fun, but it’s crying out for a remap and feels like it’s got plenty more to give.

18 inch wheels drive SO much more comfortably than the 19, sync 3 / car play / cruise control is game changing, heated seats / screen / steering wheel makes me feel fancy, and I’m disappointed in the Sony sound system.

I’ve got some boost hoses and an intake on the way, a stage 1 ecu map and I think she’ll be just fine for me.

Any other TDCI modders willing to share their 2 cents?

Trying to figure out what my best TRACK FOCUSED coilover option is for around $2000.

I’m currently looking at fortune auto 500s, silvers Neomax w/swift springs, bc racing RM series w/ swift springs, or red shift competition coilovers

This car is NOT a daily, at most my girlfriend will take it to work once a month so it doesn’t ever sit for too long. The entire purpose of this car will be for AutoX and HPDE events at a local road course. Planning on doing at least 1 event a month

No I do not want bilsteins and springs, I’ll be choosing a custom spring rate for whichever coilover I go with.

Info from anyone who heavily tracks their focus would be awesome. Thanks!

Running good solid healthy numbers on my Cobb and sounds pretty good if you hear anything that I can’t lmk just trying to make sure everything is working good after extensive repairs

Anyone got trailer hitch recommendations? Looking to get one installed for my move back east. PFA

Went up a size. Feel great. Kinda want alil bit of spacer now 🤷‍♂️🤨

This only started happening within the last few days and it's driving me nuts.

I'm sure it's not hard to actually change, but all I have are ramps and it's kind of in a hard location to get to. Any tips, or should I just go to an exhaust place?

I have been noticing some weird popping from the exhaust immediately after clutching in to shift, usually around 3k+ RPM

I checked the fuel trims with a buddy's scanner and the long term trim was at a +9% while the short term trim was bouncing between -5% and -18% depending on RPM

I figure I might swap the CPV just because I purchased the car at 13x,xxx and it is now around 150,000 and I have no idea whether its been done at all.

Outside of that, I'm not sure what else to look out for.

Any advice or tips would be great.

I am curious is this fine like this? Both the downpipe and exhaust are 3 inches but the flanges where they meet are different sizes.

I was recently gifted a small boat, and since the only car I own is a 2015 Focus ST. I think it worked well. I probably won't be able to use every boat ramp, but it still allows me to get on the water.

Hello all, are these and okay replacement for the O2 sensors in a 2014 Focus ST?

Flirting with the idea of replacing my 2010 Outback 3.6 with a similar aged MK2 Focus ST. Pretty much all for experience reasons, 5cyl noise, manual transmission, "slow" car, fast fun.

There are none in my area I can go check out so just want to know how the cars have aged, with particular interest to the interior. How's the fit and finish, have the plastics held up. Has it become a rattly shit box or is it good enough - I recognize this is going to be a step down in comfort and fit and finish over the outback but just trying to get a gauge of how much, if that makes sense.

Anything else a prospective owner should be aware of apart from the cylinder walls cracking?

Figured I'd share a little tunnel Audio I got a while ago. Little traction loss at the beginning. Noise mods are Boomba bov, mbrp cat back, depo catless downpipe, and a resonator delete.

Im planning on doing the fluid change sometime next month but want to get ahead of the inevitable master cylinder leak if I can. What all goes into replacing it, and is it worth my time doing so? Or just waiting until it gives out. Lmk!

I know this is dumb, but I picked up some mint 2014 ST3 seats to swap into my 2017 ST1 without researching much and apparently they aren’t plug and play. Has anybody done this DIY? If I got it done professionally where would I even go? I’m not too worried about the heating element as much as I am the airbag and passenger sensor.

Sun!
