    Hello, I bought my 2015 Focus ST about a year ago at around 74,827 miles. The car came with a Cobb cold air intake and a chopped exhaust as far as i know. This led me at the time to believe that this was someones first "fun" car or first car which means it could have either been beat on or...

    I am pulling the engine/trans from my 2017 FoST very soon (cylinder #4 ringland), and I have limited room in my garage.

    Hi all! I recently had the piston rings on CYL 1 fail and am in need of a new engine. I've seen some threads on escape engines working as replacements but didn't know if fusions were compatible as well. I have a 2014 ST and have been looking for that year for a donor car.

    Wanted to know if anyone has gone through this? I've got a slow leak in my coolant system. Local Ford dealer has tried a few things but nothing has truly stopped the leak. I have a "monster" warranty and now Ford Corp is sending me to different shop. Any insights on what this might be?

    Last winter I started noticing an engine RPM dependent rattle when the temperatures got into the 30's (Fahrenheit). Seems to be air temperature related more than engine temperature related. Searched and read a few posts relating to engine temperature related rattles, but they don't seem to...

    Hi all, I am in the market for an st and I have just been to test drive one. The car pulls fine and has passed its MOT, and doesn't have any visible cracks or leaks in the turbo intake. However, when I had the car idling with the hood up, I noticed a blow of air coming out from under the right...
