Question about 2000 Hyundai Accent
Posted by Anonymous on
Have someone get their ear down near the head mating surface while the engine is being turned over, and see if they can hear air whooshing through a gap or something.
Verify that the cam is turning.
Remove all the spark plugs, seal off one of the holes with a thumb, and see if there is any compression at all while cranking. If there is sucking and pressure on every stroke, the valves are not operating at all.
Turn the engint to top dead center on the No. 1 cylinder. Remove the valve cover(s).
Using the firing order, find the cylinder that is exactly opposite the No 1 in the sequence. As you move the engine back and forth past TDC and back, either the No 1 or its counterpart is transitioning between the exhaust stroke and the intake stroke. On one or the other you will see the ehaust valve just finish closing and the intake just starting to open as you cross TDC. If that is not the case, the cam is not timed properly, and compression can be realy affected by that.
With no compression at all it really seems that the problem is something common to all of the cylinders...
If the cam is operating properly, and at the right time, then perhaps something is holding the valves from closing all the way.
If the engine was moved through TDC or BDC or both without the cam turning, or with it mistimed; or if the engine was at TDC or BDC and the cam was turned, it is possible that the valve heads were bent from contact with the piston(s).
