Engines make power by burning fuel, and this is limited by the amount of air or rather oxygen that can be drawn into each cylinder. Some engines have a single inlet valve and a single exhaust valve. This would be a 2 valve per cylinder engine. So your average 4 cylinder car would have 8 valves. Some cars are 16v or 16 valves! The reason for this is that 4 smaller valves have lots of advantages over a pair of bigger ones! The main one as far as we are concerned is that a 16valve engine or rather a 4 valve per cylinder engine flows more air and makes more power than a 2 valve per cylinder one can.
the valve will need to be replaced if it indeed hit the piston . good if the valve did not puncture a hole in the piston.. but if a rocker arm is broke, count your blessings.. repair cost is just minimal.. check the push rod, i would definitely replace the lifter on that cylinder,... come to think,, why is the lifter stuck? bad oil? wrong viscosity oil? dirty engine? wrong engine temperature? if this question is not answered, expect more or similar engine problem in the future.. good luck
There are several things that could be wrong with the valve. It could be bent or the valve head broken off. It is no big deal to pull off the valve cover and take a look. The problem should be obvious. It is possible that if the valve head broke off or if the valve is stuck open because a broken spring or other reason, that the piston have be damaged or perforated by the valve. This will require a major overhaul.
