Will a piston burn a hole in as a result of a binding exhaust valve?

A hole in piston is caused by extreme heat! most likely cause is coolant being introduced into the cylinder during combustion from a leaking head gasket,faulty intake manifold gasket or a defective cylinder head!

What is the Difference between inlet valve and exhaust valve?
the difference is that the inlet valve takes air (oxygen) from surrounding in order to combution of fuel which result in blast by air fuel mixture and piston rotates while the exhaust gases removed from the exhaust valve.again the inlet valve opens first before blast and exhaust valve opens afterward
Exhaust valve smaller or bigger than intake valve in a turbo charged engine?
the exhaust valve will always be smaller as the piston is forcing the combusted gases out. The intake valves have to be bigger as the piston is only drawing the mixture in through sucktion.
How would oil get into exhaust system?
Worn piston rings, bad valve seals,
Why we open the inlet valve on the exhaust stroke and the exhaust valve on power stroke?
While there may be some overlap of valve opening timing, generally speaking, the exhaust valve opens after the power stroke, and the intake valve opens after the exhaust stroke. Recap... We start the combustion cycle of a standard 4-stroke engine with the intake stroke, the intake valve is open and the vacuum created by the downward movement of the piston draws in the air/fuel mixture from the intake manifold. The intake valve closes as the piston rounds bottom dead center and the compression stroke begins on the upward movement of the piston. At or near the top of the compression stroke, the spark plug fires (both valves are closed at this point) and begins the downward power stroke. As the piston rounds bottom dead center again, the exhaust valve opens to allow the piston to push out the exhaust gasses during the upward exhaust stroke. As the piston gets to the top, the exhaust valve closes and the intake valve opens to start the process over again.
What if valve on a engine is not flush?
you could break the valve on intake or exhaust stroke top of piston could hit it
What causes your 350 Chevy to not have compression on number piston?
Type your answer here... Burnt intake or exhaust valve, hole in piston, broken piston rings, bad head gasket, valve spring broken.
How does an engine exhaust valve get bent?
the valve bent because the piston hit it, due to a weak valve spring or over revving the engine
What can cause exhaust to come out the sides of your egr valve?
Worn piston rings and or clogged EGR system and or failed EGR valve
Steam engine piston valve?
Yes, steam engines do have pistons and valves. The piston valve is shaped like a piston hence its name. It used to control the flow of live (boiler) steam into the cylinder and the flow of exhaust steam out of the cylinder.
What would cause excessive exhaust fumes from car when started?
valve guides or valve guide seals or piston rings. in colder weather?
Describe the position of the intake and exhaust valves during most of the power stage in four-cycle gas engine?
All right. Well, let's start from the end of the exhaust cycle (piston is up). The intake valve opens as the piston goes down, sucking in the fuel/air mixture. The valve closes when the piston reaches the bottom. As the piston makes its way back up, it compresses the mixture and near the top the spark plug ignites the mixture. This explosion sends the piston shooting down again and as it comes back up, the exhaust valve opens and the piston shoves waste gasses out of the engine. Then that valve closes and the cycle starts all over again.
What could white smoke coming from the exhaust manifold mean?
Couple things. 1- worn valve seals letting oil in the combustion chamber. 2- worn piston rings -same result. You probably have a cracked head on the exhaust port.
