Hi Folks,

My Ford contour 99 model timing belt broke when driving. Its engine is 2.0L L4 DOHC.

I took it to mechanic he says its an interference engine and it has damaged the cylinder. He did the compression test in front of me and 2 of the cylinders leak 30% of the air.

I google this information online and found this engine is not an interference engine. I called the dealership they also say its not an interference engine.

Now before the timing belt broke the exhaust was loud and I wanted to take the vehicle to mechanic a week before the timing belt broke. Does this imply anything. Does this mean the cylinders are damaged or could it be something else.

I appreciate any suggestion.

Regards.

If it is not an interference engine, then the valves should not have been damaged by the bad timing belt. Was the compression test done after a new timing belt was installed?

https://www.2carpros.com/diagrams/ford/contour/1999

Valves sometimes leaks when carbon deposits fall onto their seats and with piston away from TDC, tapping the valves might cure the problem.

Can engine be started now?

Loud exhaust should have noting to do with the problem but if engine had poor performance and hesitation, there is a possibility the problem was there before the timing belt broke.

The timing belt is not yet installed and we can not start the engine. Waiting to know if it is worth spending any money on the this vehicle. First I need to know exactly if this is an interference engine. Is there any way to check if the engine is interference engine.

This engine is NOT an interference engine and to test compression, you need to have the timing belt installed.

If the timing belt was not installed, how was the compression tested?

I believe you need another opinion. The mechanic does not seem to know what he is doing.

Thanks for your response. For the compression test, he aligned the shafts and through the spark plug hole he feed the air and with the compression gauge he measured the leak. But the timing belt was not installed. I am curious to know how did you find the engine is not an interference engine. I will probably take it to some other mechanic I guess.

Thanks for your response. For Compression test mechanic aligned the shafts first for every cylinder and then used the compression gauge with one side showing the pressure applied to the engine through the spark plug hole and the other side the return pressure from the engine. But the timing belt was not installed. Not sure if this is right. I am also curious to know how did you find the engine is not an interference engine. I will consider your recommendation and take it to an other mechanic.

Our database ibndicates it is not an inteference engine. Technicians within the circle have encountered skipped tooth and broken belts and none have mentioned any problem with the valve trains.

So does anyone Know if an accurate Compression test can be taken without replacing the timing belt? With VCT, would just aligning the shafts be adequate?

That was not a compression test that he performed, it was a leak down test right? A compression test won't tell you what percentage of loss you have. And this motor is not an interference motor.

That is not how a compression test is performed. It must have been a leak down test, in which case you still need the belt to be installed.I would seek another opinion if I wee you.

I have changed the timing belt 3 times now, and they all keep shredding on the timing belt cover, I changed all the components the first time, I've gone through it thoroughly and can't see whats making the belt pull out and shred on the timing cover. I did take the crank shaft gear off for the timing belt and theres a washer, I can't remember is it suppose togo between the engine block and gear Or the gear first and then the washer? Please help! Thanks please tell me all possible causes

I believe it goes second. If that is the case, the pulley may be forward too far causing the belt to walk off. Also, you may want to use a straight edge to make sure the pulleys are even.

Let me know what you find.

Hi, I recently changed the timing belt. About six weeks later the belt needed changing again.I replaced it again, I decided to check belt condition. After removing the coverI found the belt had been wearing on the cover. The belt was drifting off the gears. What needs to be replaced?

No, if that is the original engine, it is NOT an interference engine.
