The Nissan CG13DE engine, which was installed in the Micra (March) and other compact cars, is quite reliable and easy to maintain, but over time it can develop some problems. Here are the main ones:

1. Timing chain wear:

Over time, the timing chain can stretch, which leads to changes in valve timing and can cause misfires, loss of engine power and even valve damage if the chain jumps a few teeth.

2. Oil leaks:

Over time, oil leaks can occur through seals or gaskets (for example, the valve cover gasket, crankshaft seals and camshaft seals). This can lead to low oil levels and, if not monitored, engine damage due to lack of lubrication.

3. Engine overheating:

Problems with the cooling system, such as a faulty thermostat, clogged radiator or a failing water pump, can cause the engine to overheat. This can cause warped cylinder heads and damage to the cylinder head gasket.

4. Clogged Fuel Injection System:

Fuel injectors can become clogged, causing uneven fuel delivery to the cylinders. This causes loss of power, rough engine operation, and increased fuel consumption.

5. Sensor Failures:

Sensors such as the crankshaft position sensor, mass air flow (MAF) sensor, and oxygen sensor can fail over time. This can cause engine misfires and starting problems.

6. Excessive Oil Consumption:

Some CG13DE engines may experience increased oil consumption, which can be due to worn piston rings or valve guides. This can result in blue smoke from the exhaust and reduced compression.

7. Incorrect Ignition System Operation:

Spark plugs and ignition coils can fail, causing misfires, rough running, and loss of power. Replacing spark plugs regularly can help prevent this problem.
