Jumped time single overhead cam did valves mess up when jumped time

The torque specification for the rocker shafts on the 2001 Hyundai Accent with the 1.5L single overhead cam engine is 18-20 lb-ft. The proper torque sequence is as follows:

1. Tighten the bolts to 8 lb-ft in a crosswise pattern.
2. Increase the torque to 15 lb-ft, again in a crosswise pattern.
3. Finally, tighten the bolts to the full torque of 18-20 lb-ft, again in a crosswise pattern.

Make sure to use a torque wrench and follow the sequence carefully to ensure proper tightening and prevent damage.

it has engine damage most likely due to the broke timing belt its a interference engine and probably bend valves

Hello- Yes, you have to remove the timing belt in order to remove the water pump. If the belt was just placed back on the pulley without setting the timing marks, then the engine is out of time. There were two engine types that your Mazda could have been equiped with; a single overhead cam or a double overhead cam (you did not mention which). In any case, do not try to start the engine anymore, you could damage the valves due to piston to valve clearence caused by the engine to be out of time. Comment back with the engine type and/or if more assistance is needed.

There is no such thing as a dual overhead gasket or a single overhead gasket.... there is, however, the existance of a dual overhead 'cam' and a single overhead 'cam'...

Please restate your question

if it's a dual overhead cam then each head has two cams and two pully's, a single overhead cam engine has one cam and one pulley on each head. if the belt has more than 60,000 miles on it you should replace it. you need to find out if the engine is an interference engine or not to determine the level of damage caused if the belt has jumped or slipped. your overhead cam timing marks are usually on the cam faces and the backing plate behind the cam or sometimes there's two marks on the cam that you align with the surface of the head behind them. the first thing you need is a diagram of the belt routing and mark positions because timing marks are very important especially on an interference engine. starting or cranking an interference engine with the timing marks misaligned can bend all your valves or even punch holes in your pistons! so proper alignment is crucial, good luck.

oops ,bent valves

Unfortunately, your question is very vague and hard to understand.

16 or 32 cam?
Usually your engine will have twin cams, or single cam.
Overhead cam(s) or not. You could determine if your engine
is a 4 or a 6 cylinder, and then you will generally find out how
many valves the engine has.

If you are in a 4 cylinder car, you probably have 16 valves if you have a twin cam engine.
If you have a single cam, 4 cylinder engine, then you will usually have only 8 valves.

The only way that you could end up with 32 valves, is if you have a dual overhead cam, v-6 engine.
Each head will have two cams, and each cylinder will have 4 valves then.

I hope that this is what you were trying to ask. :)

Look at the 8th digit on the vin #
3 = Duel
P = Single

If you are sure that the engine is out of timing, better not try to start it until timing is fixed. Most overhead cam engines will bend or crack the valves/lifters if the timing chain has jumped a few teeth.

Pretty easy to tell even without taking the valve cover off.
If it is a dual cam, then the spark plugs are lined up right down the middle, between the 2 cams.
Which is optimal.
If it is a single cam, the plugs have to be off to one side, on an angle.
Which is not as good.
