Good day everyone!! I have a focus st. I bought it a month ago it has 125k miles on it. Maintenance up to date, catless down pipe, iridium spark plugs gap at .28, Cobb access port v3, tune stage 1, green filter. A week ago or so it started to smoke only when idle when it reach it’s normal temperature. There’s no leaking coming from the car from what I have check under the car. It’s missing the crankcase breather. And a few weeks ago I spill oil by mistake near the crankcase breather and the turbo. I went to a mechanic near and he told me there’s nothing wrong with the engine. There’s no code thrown and car is running fine. I can hear some misfire sometimes but nothing crazy. The only problem is that when I go to work and I stop at a red light at idle star to smoke.
