| Description of the problem | I was driving on the freeway when my car started driving rough. It made some loud clicking sounds and started to misfire and stutter. The next day i took it to the mechanic and he said the oil was empty, but i had just had the car in for service a few months earlier and there was no problem. The check engine and oil lights didn't illuminate. He did an oil change and tune up. The car continued to ride rough. I took it back to the mechanic a few days later and the oil was low again. There was no oil leak. He checked everything again and said it appeared the spark plugs were failing. Two weeks later i had the same problem again. I added oil. I took it to another mechanic (i was out of town). He cleaned the spark plugs. Four days later the car started acting really horrible, making loud clanking noise and stuttering. I added oil again and took it back to my original mechanic. He treated the oil and asked me to come back in a week so he could monitor the problem. The car drove smooth and without any problem then one week later, while driving to the mechanic the car made loud clanking noise and a cloud of white smoke came from the car. I had it towed to the mechanic. He is looking to replace my engine. In all this the indicator lights never came on (oil or check engine). |
