LEFT A STOP LIGHT AND CAR HESITATED SO I GAVE IT A LITTLE MORE GAS. THEN THERE WAS LOUD METAL TO METAL NOISE FROM ENGINE AND AN EXPLOSION WITH WHITE SMOKE. ABLE TO GET INTO A PARKING LOT AND OPENED THE HOOD TO A SMALL FIRE. FOUND THAT THERE WAS A HOLE IN BACK OF ENGINE AND CRACKED THE FRONT. IN THE OIL PAN WAS THE ATTACHMENT ARM FROM THE CRANK IN MANY PIECES. THERE IS A RECALL WITH HYUNDAI BUT KIA SAYS IT IS NOT RELATED TO THIS ENGINE WHEN THERE IS AN ARTICLE STATING THE ENGINE DID GET PLACED IN THE KIA OPTIMA. I HAD JUST UNDER 100K MILES AND AN OIL CHANGE JUST 2 WEEKS PRIOR DUE TO LOW OIL PRESSURE. THIS WAS DONE AT A KIA DEALER AND THEY SAID THERE IS NOTHING WRONG BUT CHANGED THE OIL AT $70 DOLLARS AND SENT ME ON MY WAY. WHERE DO I GO FROM HERE? SEE PICTURE OF PARTS ATTACHED.
