When Honda models rhyme (Stream) vehicles, model JHMRN3, 2002 model year, the cumulative traveling 190,000 km.
Symptom: the engine is cold (in the morning) does not start.
Troubleshooting: The car is the first time I was dragged to plant maintenance.
Test found that the SVDI VAG engine is indeed difficult to start, but the starter is operating normally. First, check with HDS, trouble-free code. Then check the ignition system, disconnect the ignition coil wire side of the three-pin connector cable, turn the ignition switch, measure the voltage of the power supply terminals for the battery voltage is normal. Then remove an ignition coil, spark plug mounted on the standby flashover test, spark plug arcing normal operation of the starter, then remove the spark plug to check the car, found four spark plugs have been soaked in petrol head, when it replaced the 4 only the spark plugs, and then test found that the engine can be started immediately with the machine, check with HDS, no abnormalities, the car factory.
On the third day they can not start the car engine, drag to plant dismantling and found gasoline spark plug has been flooded wet, so regular checks. Measurement of cylinder pressure, were about 1.1 MPa, normal. After cummins insite measuring the fuel system pressure is 320 kPa, the pressure to keep the flame 30 min at about 150 kPa, fuel system pressure is normal.
Check the engine with the HDS data stream, also found no abnormal data. Remove the injector testing, each injector fuel injection quantity and atomization well without fouling and leakage phenomenon. Because when the spark plug engine can be started with the drying machine, indicating that the car has an engine start conditions, so the car will be parked in the shop and so the next morning to check again.
The next morning before starting the engine remove the spark plug first observed no petrol head attached to ktag observe the interior of the cylinder through the spark plug mounting hole, with a strong flashlight visible liquid piston crown seems to have the presence of a thin wire with a fixed period of approximately 20mm long White touches top of the piston to obtain the top of the liquid. From the point of view of the liquid sample is not gasoline, antifreeze should be to check the remaining three cylinder piston top, but also have the presence of liquid, thus analysis of phenomena, suspected cylinder head gasket is damaged, but the owners reflect the engine temperature has been normal, check the tank and found antifreeze less about 1.5 L, add enough liquid to cool the machine after starting the engine, can be seen from the mouth of a small amount of added liquid bubbles emerge, accelerating the bubble increases, thus conclude that indeed cylinder head gasket is damaged.
Decided to replace the cylinder head gasket. Remove the cylinder head inspection, the cylinder Transponder Chip head flatness error in 0.15 mm or less, you can continue to use. After replacing the cylinder head gasket test, the engine start-time success. The next morning and then start the test, the engine smoothly with one-time machine, the failure to completely eliminate.
