MOST LIKELY IT NEEDS TO BE TENSIONED PROPERLY OR, THE TENSIONER IS FAULTY.ALSO OVER TIME THE BELTS STRECHES AND NEEDS REPLACEMENT.
try changing both timing gears
most snapped timing belts will in most cases cause engine damage,the only exception would be a freewheeling engine were valve to piston contact would be minimal an interference type engine would cause damage.
The ignition timing on Contour engines is controlled by the computer, and is not adjustable. However, if you're talking about the 4-cylinder 2.0 liter, it uses a timing belt for the cams, and if it is worn and slips a tooth, it would cause some real problems. (The 2.5 liter V6 isn't subject to this, as it uses a timing chain for the cams.)
According to Gates ( they make timing belts etc. ) the 2.0 L - DOHC - 4 cylinder engine in a 1997 Ford Contour is NOT an interference engine - so the answer would be NO
No. A worn timing chain or belt would cause timing to jump.
I don't have a Contour, but if it has a distributor, then you use a timing light and simply twist the distributor cap to change the timing. If it has coil packs, then it's all done electronically, and you can't adjust it. If your timing is still off, you have a sensor somewhere feeding the ECU bad info. ====================================================== All of the Contour engines' ignition timing is controlled by the computer, and is not adjustable. If there were any sort of problem in this area, the computer would turn on the "Check Engine" light and store an error code.
I'm not a mechanic / technician but I would say ( no ) According to the Gates website ( they make timing belts etcetera ) the 2.0 liter four cylinder engine in a 1995 Ford Contour ( IS NOT AN INTERFERENCE ENGINE )
have you checked the fuses?
Your timing chain may be worn to the point it is jumping a tooth and thus changing the timing. If you can hear the chain that is a good sign it is worn. I would inspect the timing chain.
my best opinion is the timing belt has become loose after re doing the timing so many times. this means a new timing belt is needed
The only reason the timing would have jumped is if the belt has lost some teeth which it will do right before it breaks. The timing belt should be replaced before the car is driven or the motor started again. If the belt breaks while the engine is running, it can cause major damage to the head and possibly the block.
Why would a timing belt jump time and cause damage to the cylinder heads ?
