ok got myself into a bit of trouble 2 nights ago when i drove my alfa 145qv through a huge puddle. i know i was stupid drivin through it but it was dark and it was raining really hard so visability was terrible. the puddle didn't look to deep but it was so deep that even the lights where covered. towed the car home and its been drying inside the garage with a fan blowing on the engin bay. everything lookes dry but when start the car it makes a terrrible noise like a tak tak tak. sounds as if a belt has slipped and is hitting against something as it spins round (it increases as i accelarate.) but i cant see any belts that are loose. anyone know what is causing this to happen? my brother decided to check the spark plugs and pulled one of those long leads for the tspark plugs out and now it won go back in. any special way of putting these back?
