Do the valves hit the pistons when the timing chain skips on a 1998 pontiac 2.2liter?

no, if they did the valve would rocket out of the engine.
Reply to This nonsense^ YES the valves are controlled by cams, which are controlled by your main crank! When the chain jumps and the cams become misaligned with the cylinder the piston will come up and hit the valve(s). Your cam will push the valves down while piston is coming up making contact with each other ad either bending your valve(s) or breaking them, thus losing compression!!

Why do engines blow when timing belts break?
The timing belt is what keeps the valves from moving in synch with the pistons. If the timing belt snaps or cogs over the pistons are likely to collide with the valves smashing them both.
Whats the problem Peugeot 106 no oil in the engine and the pistons bent all the exhaust valves changed the 4 valves and the pistons are still hitting the exhaust valves and the valve timing is right?
your timing can not be right
Is a 1999 Daewoo leganza a zero clearance engine?
YES THE VALVES WILL HIT THE PISTONS IF TIMING BELT JUMPS OR BRAKES YES THE VALVES WILL HIT THE PISTONS IF TIMING BELT JUMPS OR BRAKES
300zx Nissan broken timing belt damage engine?
ANSWER YES, The valves will hit the top of pistons and either the valves will bend or the pistons will be destroyed.......
Why does car turn over then stops like its jammed just had new timing belt?
If a new timing belt was installed but the valve timing does not correspond with the pistons ie: the valves opening as the pistons reaching top dead centre ,,then it will be jamming.. bending valves and possibly damaging pistons.. when fitting a new timing belt or chain you have to be very careful of cam/valve position in respect of the pistons
What happens if a 1995 Honda Civic ex timing belts breaks?
Usually if the timing belt breaks you have to replace the head or the bent valves. Sometimes the damage can be much worse and the entire engine can be wiped out. When the timing belt breaks, your cams and valves stop moving but the pistons don't. The pistons will smash against the stopped valves and bent them and on some occasions can break pistons as well.
What can a broken timing chain damage?
On an interference engine it can damage the valves, heads, and pistons.
What type of engine wont let valves collide with pistons when timing IS OFF?
Noninterference
What is a interference engine?
an engine where, in the event that the timing is off or if the timing belt breaks, the pistons can collide with the valves and actually do damage.
What can be damaged when a timing belt breaks?
The valves can hit the tops of the pistons damaging or breaking either.
Will an engine seize from jumped timing?
It could if the valves made contact with the pistons in an interference engine.
What if the crank to cam timing gears are off?
The engine will not run, possibly damaging valves and pistons.
