Continual oil leakage from the lower engine block of a 2002 Ford Focus 5 door hatchback. This results from an engineering problem, per my firestone service person. The right side cv axle mounting brackett is attached to the lower crankcase, and the axle torque has over the 73,000 miles we have driven the vehicle cracked the lower crank-case. When there is pressure on the engine, the crack opens and oil leaks. I have seen the crack with my own eyes. According to the technicians, if this is the case with this vehicle because of the engineering, there are probably other instances of the same thing happening.
When turning on my 2002 Ford Focus zx3, it tends to have a very rough idle, sputtering and stalling. I have replaced the fuel filter, spark plugs, spark cables, pcv valve and my ignition coil. But even after all of that my car still sputters, stalls and has a rough idle. . . . I don't know what to do, being a college student out of my home state of michigan. I have taken it to auto zone and had it hooked up to the code reader and the attendant said everything was fine. . . This is my last straw. .
