I have a Chevy Spark 2008 800cc. I need the tappet settings please?

Does it have spark at the spark plug's ?

You need to take off the timing belt (or chain) cover and see why the one camshaft is not turning. Maybe the belt for that cam broke or the cam has seized from a bad cam bearing. One camshaft should be for the intake valves, the other cam is for the exhaust valves.

Make shore valve timing is correct compression test all cylinders same new spark plugs set ignition timing check ignition leads and vacuum hoses adjust tappets .make sure crank shaft on TDC cam shaft on number one cylinder valves close and cam pulley on marks belt tide fit distributor firing number one cylinder line up rotor and distributor cup lead to that .

Hi Robert, It would help to know what engine is in your vehicle? A rule of thumb way to set up the valve timing is as follows. Rotate the crank shaft until the crank shaft mark is about 90 degrees from TDC. This will protect the valves from damage when rotating the cams to align them. With the tappet cover removed rotate the cam shaft or shafts so that the number one cylinder is on compression (both inlet and exhaust valves fully closed) and the last cylinder in line on overlap, Look for adjacent timing marks on the cam gears and somewhere close to those look for the alignment marks (maybe notch marks, holes or indented match marks). (Some manufactures use the machined gasket surface where the tappet cover closes onto the cylinder head). Look closely for the static mark on the cylinder head and align the cam(s) to it or them. Once completed, set the crank at Top Dead Center and look carefully for a timing mark which aligns with the gear and set them. Fit the belt so the marks align when the tensioner bearing is released and presses the belt under load. (follow the manufactures recommended tightening instructions.) . (Remember never to crimp a timing belt, if it has been, throw it away and get another, even if it is new!) If the belt snapped and that is the reason for replacement, internal damage may have resulted inside the engine. A snapped belt may cause damage to the valves, the camshafts, the cam shaft caps and to the pistons. If the engine turns much faster than expected and sounds as if there is no compression, you have problems! (Those I've just mentioned. I hope not for your sake. best of luck Regards John

my books show it as a interference engine in which case valve damage is most likely to occur
however if that was the case , it would be having a miss from the start and would not run 2 weeks before something happened
if a valve spring breaks there could be valve piston contact but it is doubtful if that would destroy the engine but again breaking valve springs is rather rare on diesel engines
the engine would not just quit but would rattle and bang it's head off then develope a big noisy miss from a hole in the piston
so I suspect a timing belt problem from when they removed/replaced the head after the glo-plug fix or a crank/cam shaft position sensor or wires ( possible faulty connections for the cam shaft)
I would suggest finding an accredited service center for a proper diagnosis and quote for engine repairs

Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.

you will need to open the engine up if you can not turn the cam fully. something has been bent or broken or else it will turn. by breaking your timing belt was it shredded? if so you do have internal damage

this is a interferance engine and the valves are bent the head needs reoplaced

Hello momma_green: My name is Roger and I will help you. The 2005 Chevy Aveo 1.6 engine is a interference motor. That means if the timing belt breaks.The valves will be bent. I have one in my shop now that the belt broke on it. Bent all 16 valves and damaged all 4 pistons. This is not a forgiving motor. I wish I could tell you good news but I cant. Should you need further help please just ask. Please rate the answer you received. Thank You for using Fix Ya. Roger

It may be one tooth off. That all it takes. One tooth on the belt of the crank or cam. The computer gets it's spark pulse from a sensor on the crankshaft. If it gets the pulse a fraction of a second to late or too early it won't time correctly. Check it out one more time. Hope this helps. Good luck and thanks for using FIX-YA.
