If the pistons are bad it should be smoking a bright blue color out of the exhaust. Are if a piston skirt is broken it should be knocking all the time. If there is a whole burnt in the piston you will not have any compression on that cylinder. Most of the time pistons just don't go bad.
well if the pistons wont go 'up or down' it wont be taking in any fuel, wont compress it and then wont react with the spark .... car is going nowhere
The Detroit Pistons
your cam-shafts could be broken pistons could be bad or you could be driveing a ford
it get rusted
Pistons are a major part of the engine and if one goes bad there ain't no fixing a piston, replacement is necessary.
they dont work
It changes the TIMING.
if you know if their bad you can report them
The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.The compression stroke is not part of the engine. It is what happens when the pistons are on the upward with closed valves.See link below.
The pistons stop going up and down.
It comes from the gasoline. the gas is injected to the pistons where a small explosion happens and driving the piston up, all the pistons work together to turn the drive shaft thus making the car go. that is the very simplified version.
