Question about 2006 Hyundai Accent
I put on a new timing belt and got everthing to TDC but ow it is runing rough and thereis a knock in the motor. is there a way to tell if i have damaged rod(s)or damaged valve(s)with out tearing it apart first?
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

Use a compression tester to see if the cylinders build compression. If the do, probable rod issue, if they don't then it is valves. For the record, Hyundais would bend valves if the T-belt failed. That is why it was a 60k recommended replacement.

With regrets, Not likely, pull the vlave cover and observe the height of the valves, if it is bent it should be not quite as tall as the rest.

hi from uk to retime cambelt is as follows = the crank cog has a mark which lines up with corresponding mark on front of engine block mark is approx 12-30 o/clock this is TDC No 1 the the cam cog has a small drilled hole in one of the webs just below the cog teeth ? this hole has to be at 12-o/clock position and then using a small mirror if you look through this hole you will see a vertical notch on the front of block this is theTDC mark for cam you then fit belt anticlockwise from c/shaft to cam then round tensioner then release tensionor to tension belt and then lock it up torque both bolts 20 - 27Nm rotate engine manually 4 complete turns clockwise then recheck marks ok /re align ? then re assemble crank pully bolt torque is 140 -150 Nm may i just inform you? that your engine is what is known as interferance that is to say in event of c/belt failure there is more than likely valves to piston contact however this can also occure too if miss timed belt fitted and engine has tried to start ? a compression test on cylinders will confirm if this has happened or not ? hope this helps

Hard to say. Depends on how fast the engine was running when it broke. Sounds like pretty fast from the belt getting mangled, right? You can put a new belt on and see if the engine will turn. If not, you know you've at least got some bent valves that are not seating. You can also loosen all of the rockers to see if that will let the engine turn--then you wouldn't have to buy a new belt before deciding whether or not to fix the motor.

SOURCE: Timing belt broke at about
change the timing belt remuve spark plugs give wet and dry compration on cylinders start the engine by slowly exalaraiting to 2500 rpm ef not noise you are ok good engine has to run with 1/2 of the cylinders.
