broken timing belt,how much are the repairs?
5 Answers
Can't estimate with out knowing how much damage was done. On some cars with interference engines, the valves bend and a replacement head is needed. On some cars, the pistons are damaged and a replacement motor is installed. --- A used motor should be around $1250-$2000 installed. It could be more - that is a real rough number. --- Assess the damage and get real estimates from your local shops
The 2008 Mazda CX 7 Sport has a 4 cylinder 2.3L engine that has a timing chain. it's a Ford Duratec L3-VE or L3-DE...what happened exactly that made you think it broke? Are you confusing it with the serpentine drive belt?
And if so, if you do it yourself, inexpensive

DavidH25 - a similar thing happened to a car that I intend to buy 2007 Mazda CX7, the car is not staring now and it was left aside for 6/ 7 weeks. I was told the lady was driving the car on a highway and the car suddenly started slowing down and she managed to stop on the shoulder and had it towed to a mechanic shop that advised that it could be that the timing chain fell. I have read other posts mentioning that the damaged timing chain in the CX7 will also effect the VVT. is that tight? My main question is with the way the CX7 motor is designed what are the possibilities of this problem causing damages to the pistons or the valves. I was told the chain foul cause valve damage on some types of motors but could cause pistons damage on others. Thank you in advance...
CAR HAS BEEN RUNNING GREAT. WENT OUT TO START IT IT KICKED RIGHT OFF. ABOUT TWO MINUTES LATER IT STARTED TO MAKE THIS KNOCKING NOISE. I THOUGHT MAYBE A PIECE OF ICE WAS UNDER THE HOOD. ( I LIVE IN WYOMING AND WE JUST HAD12inces OF SNOW FALL ) ANYWAY I PUT IT IN REVERSE AND AS SOON AS I DID IT STARTED MISSING I THEN PUT IN PARK AND OT MISSED AGAIN AND SHUT OFF. I TRIED TO START IT BUT NO LUCK.
