Your going to have to replace the timing belt.Then...Get a socket on the bolt that holds the pully onfor the belts (AC, Power Steering, Alternator) and manually turn the engine over a couple times, if it gets hard to turn over at any point you still have compression, if its effortless expect valve damage.
When a timing belt breaks, it may damage your valves or pistons, due to piston and valve contacted. The best way to confirm damage, is to replace with timing belt, reset the engine and perform a compression check, typical psi should be around 170-200 psi on each cylinder.
The 1990 Stanza could have damage, depending on which engine is in the vehicle. Check to see which engine you have, and if it is listed as an interference engine. If it is the interference type, then the valves are probably bent and destroyed.
You can do a cylinder leakage test to check for bent valves.You can do a cylinder leakage test to check for bent valves.
It will do some internal damage ie bent valves being the main one. Hi I'm just half we through taken a head of a megane 1.4 coupe that had timing belt snapped. It will also cause damage to pistons as well, the amount of damage will be on how fast you was going when it let go but it will have cause damage though. If it has bent valves you may need to check the valve guides as well.
Timing marks are not lined up correctly.
Maybe it is-check your timing. Also check for exhaust leaks.
A rubber timing belt may be replaced due to age or due to condition. If a belt breaks while driving, it will result in instant stopping of the motor, frequently with damage to the valves/pistons. Replacing an old or worn belt in a timely manner is MUCH cheaper than the results of NOT replacing one. Check the price of a belt, and the price of a wrecker and engine rebuild.
i HAVE A 98 AND THE BELT BROKE TWICE AND DID NO DAMAGE TO THE ENGINE. The first time I was on freeway doing 75 and it broke. I have a '97 Contour and had no damage to the engine when my timing belt broke. Make sure you check your pulleys to ensure that the bearings are good. Mine were not and had to replace them.
It's highly likely that the valves and piston have touched, as with most modern 16v engines. I'd replace the timing belt, then try turning it over by hand, if that works see if it will start. It is however unlikely to start, so it will then require the cylinder head removing to replace the damaged valves. Check everything in the timing belt area; tensioner, idler, water pump etc, as damage or failure of any of these could have caused the timing belt to break
If you are worried about bent valves DON'T That year engine will not bend the valves when the timing chain goes bad.
Maybe, it depends on if your engine is an interference engine.
It sounds like the engine timing. The sound is coming from your engine valves. They're not in synch with the rest of your engine. It could also be that the valves are worn out. I'd check the timing first, then the seating on the valves.
