2003 Kia Carnival V6 traveling 80,000 kilometers, Last week driving on the road, suddenly turn off then couldn't start no longer. So took it to a mechanic.
First, He used the code reader, plug into the engine system checks and trouble-free. Could not beat the experience of the car that the fuel pump circuit failure, He removed the air flow meter, carburetor cleaner sprayed into the intake manifold, open the ignition key to start but no start signs, open the ignition key detection tubing pulseless dynamic, to prove any abnormal oil pump and its circuit. If the oil line is no problem, start checking the high tension ignition circuit, off the high-voltage detection ignition circuit problem, see a high-pressure fire properly, there is no problem since the oil line circuit? The next step is to check the timing and cylinder pressure. Remove the spark plug detection cylinder pressure, cylinder pressure are normal. 1.3-cylinder air pressure is less than 3KP. 5 cylinder also only 5KP around, due to the V-type engine 2 4.6. Cylinder spark plug location inconvenience disassembly, there is no check.
Accordingly, it is possible to determine cylinder head gasket leak. Because the the car engine uses wet cylinder liner, cylinder pad temperature difference and differential pressure has the old section of the cylinder pad technology, but relevant, easily washed out, as I've encountered, similarities between the cylinder and the cylinder when the piston up the compression, the gas mixture will enter the adjacent cylinder, as well as the failure of the engine can not be launched.
Remove the cylinder head, see the cylinder pad determine washed out, put on an improved gasket assembled test cylinder pressure normal are about 10KP start the vehicle, all normal. At this point, the vehicle repair is completed.
