What is good compression on a 2006 hyundai accent
i am guessin you have the 1.6l engine. from what i recall a few months back while reading through a service manual, the ideal compression ratio should be about 190psi, with a minimum ratio of 170psi. the difference in the cylinders should not exceed 20psi. based on the results you have given, i think you have a serious problem. i would recommend you try a "wet' compression test. that would atleast give an indication of whether or not the piston rings are worn out as well.
to answer your second question, the 1.6l has a total of 16 valves, four per cylinder, 2 exhaust and 2 intake.

The timing belt broke in my daughtrs 2006 hyundai accent. How or can i tell if i need new valves and or rods it doeshave a knck in it now and wnt stay idling very long when i start it
if you have damaged rods or valves in your engine, there would be almost no chance that the engine would run or even start. it is quite possible that you did not get your timing right when changing the belt. in most cases, getting the pulley to piston 1 TDC does not always guarantee that the engine timing is correct.
my advice is to recheck the timing of the engine, as well as Ignition timing (which is also controlled by the positioning of the crank pulley) before condemning any internal mechanical failure.
to answer your question, there is no written way of knowing whether your rods or valves are damaged without taking apart the engine and inspecting for damage. however, damaged internal components will always leave a trail.
you can try draining the engine oil and checking the oil for any metal filings. you can also take out the oil sump to check for any pieces of broken metal in the sump.
hope that helps
