I have a 2003 1.4 zetec fiesta. When the engine revs reach about 3000 rpm it makes a loud rattling sound which goes at about 4500rpm. Now the car will not start and sounds very different when turning over. Cam belt has not snapped. Any ideas?
You could have just dislodged some carbon that has stuck in the valves causing lack of compression. You far best let someone look at it. Your local Dealer is in Dunston there phone number is 01914607464
