If your timing belt is broken you have most probably damaged a few valves, if this is the case the head has to come off to replace the valves, usually when the head is taken off you get the head or heads serviced, that way you know all is well with the head.
I am not up to date with Porshe repairs but I would say that it will not be cheap.

2002 Mazda timing belt busted cames are not aligned how to align them to get back time


First off, we need to know the model Mazda you are referring to and the engine size installed. Also, many of these engines are known as interference engines. That means is the timing belt breaks and the cams get out of sync with the crankshaft, valves can and will be bent or broken, resulting in additional repair parts and costs.

Is kia optima V6 engine a non-interference engine


The engine is an interference engine. IF you have broken the timing belt, you are in for some serious repair costs. Depending on the amount of damage, a replacement engine may be cheaper than repairs.

Whats the cost to repair the timing belt on a Kia Magentis 55 plate


The cost if the timing belt part and labor will float around the 500.00 mark if it was routine maintenance service. Seeing how this is an interference engine, damage to head, valves and/or pistons may have occurred at which point cost will be contingent upon the severity if the damage. Price may be around the 1200.00 mark give or take. At this point it would be a good idea to weight your options.

I have a 2003 Saturn vue with 138,000 miles. the machanic says the cam shafts are not turning and the timing belt is broken . How expensive is this to do, can I do it myself ?


First you need to find out if the engine is an interference engine or free running. If an interference engine, it means the valves will interfere with the pistons if they become out of time--like when a timing belt breaks. this means the valves will hit the pistons and vice versa. Usually the valves are bent and the cylinder head must be removed to get to the bent valves and replace them. If the engine is free running, the valves and pistons will miss each other if they become untimed. So all that is needed in this case is a new timing belt. Much, much easier and less costly than removing the cylinder head.

To find out if your engine is free running or interference, check out this website:

scroll down and look for the interference check.

Timing belt broke...was told i need new engine..is this right?


The 2.4L four has a belt and is not an interference engine according to the Gates timing belt application chart for your vehicle (check it out on Gates.com.) The 2.7L V-6 doesn't show that it needs a belt--so it has either a timing chain and gears or just gears. If the belt broke on the 2.4L four, you should be able to put on a new belt and go. The engine should not be damaged.

If the timing chain on the V-6 broke then engine damage may have occurred. Chain engines are sometimes not listed as interference because breaking a chain is so rare. The damage would probably be bent valves and damaged piston tops. The labor involved in repairing all that might cost more than just getting a rebuilt engine and putting it in.

I'm currently interested in a 1996 volvo 960; without having much volvo knowledge, what do you suggest I investigate and or what type of repairs are common after 140000 miles on the car


Does the current owner of the vehicle have well kept service records? If he does, ask him if the timing belt was changed on this car. And ask him to show you the service records. The timing belt should have already been replaced, but if not, you will need to replace it immediately. Along with water pump, seals, and balance shaft belt. If the vehicle has an interference motor, and the timing belt breaks going down the road, it has the potential to ruin the motor. The timing belt on a Volvo is not for the beginner, and most shops will not even touch it. Tech will need special tools to lock down the cams, or risk even bigger issues. Also, do a visual inspection, paying close attention to the undercarriage, looking for oil leaks. Volvo's are great cars, but the routine maintenance can be costly.

Broken Timing Belt -1999 Daewoo Lanos


Well, broken timing belt causes valves to break, valves can be changed but if your mechanic wants to change whole engine then you have to change a mechanic. I had broken timing belts on few cars and never needed to change whole engine. Unless second hand engine is cheaper then new valves for it.
