The Timing chain may or may not slip with a missing tooth on the crankshaft. But i think the car would probably run. May be pretty noisy too.
If you have immobilizer in your car, sure it will prevent your from starting.
its not straight
no it will not unless the engine was extremely over heated destroying the compression
Was this car running before? It sounds like maybe the crankshaft is broken or maybe a rod came loose and is causing a bind when it cranks.
The crankshaft pulley has broken causing the outer ring to slide forward into the fan assy. replace your crankshaft pulley and all will be well
Toad the Wet Sprocket told you it's broken.
Piston seized to cylinder wall Broken Crankshaft
One of the symptoms of a broken timing belt is the engine when turned over with the starter will speed up and slow down in a rythmic pattern. Some of the cylinders have valves that are stuck open, so when the starter hits that part the engine will turn over faster, then slower, then faster etc. Also, you can tell if the timing belt is broken by flashing a light into the oil filler oil while somebody is starting the starter. If the valve train isn't moving then the timing belt is broken. Some belts don't break, they just get the teeth sheared off at the crankshaft sprocket. So they would look all right , but really weren't.
Crankshaft pulley turns with the crank, if it won't turn at all, something internally is broken.
Broken timing belt?
Usually, part of it will still be attached to the crankshaft. Sometimes, it will be in the oil pan.
No, but it can be replaced. I would recommend taking to a professional.
