Valve to piston, no. The interference is valve to valve.
yes, valve to piston interference is likely to occur if belt fails
It depends if it is an interference engine or not. If it is an interference engine there will be engine damage. Most likely bent valves or a busted piston. If it is a non-interference engine then nothing will happen except the engine will not run.
According to my research on the Gates timing belt website, the engine is an interference engine. The belt should be changed every 60,000 miles (100,000 km). If the belt has broke, normally a valve has been bent and a piston could be damaged. There is not enough clearance between the piston and valve to allow for them to work out of time with each other.
By interference, if you are referring to the valves. The 1.8 liter is a non interference engine. If the timing belt brakes, then the valves do not interfere with the piston. They do not try and occupy the same space. The 1.9 liter engine is an interference engine. If the timing belt breaks then the valves will occupy the same space as the piston and they will hit each other.
If you give the yr/make/model/engine, could let you know... But if you want to find out your self. You need to turn piston 1 to TDC and depending on the engine, undo the valve spring keeper and measure how far the valve drops until in hits the piston. Subtract .050 of an inch and if it is less than the max valve lift you have an interference engine.
Yes, they are an interference motor. the intake valve will hit the piston at full lift and tdc.
It refers to an engine where the area occupied by the valves when they are open is occupied by the piston when the valves are closed. If the timing belt lets go while the engine is running the piston will smash the open valves doing loads of damage.
The Opel Astra 2.0 16v engine is an interference and non interference. This is one of them most important aspects that any potential buyer should check. Interference engines rely using timing gears while a non interference engine has a piston that does not go anywhere with open valves.
No, this is not an interference engine.
The volume between the engine head and piston when the piston is in the head dead center piston R - is expressed in cubic inches

Depends on if the engine is an interference engine or not, and how fast it shut down when the belt broke. Interference in this case means that valve and piston reach can overlap, which very often means that when they fall out of synch they smash into each other. If it's a non-interference engine it's no worries.
