Engine — preparation for start-up after major repairs (Opel Omega A)

1. Make sure the battery is fully charged and that all lubricants, coolant and fuel are replenished.

2. Double check all joints and connections.

3. Remove the spark plugs and the negative (Number 1) wire from the ignition coil. Crank the engine until the oil pressure warning light goes out. The fuel system will also be bled during this step.

4. Connect the ignition coil wiring, install the spark plugs and wires. Start the engine.

5. Once the engine starts, keep it running at high idle speed only (no faster) and warm up to normal operating temperature.

6. When the engine is warming up, unusual smells and some smoke from hot parts may be felt. Check for water or oil leaks, which will be noticeable. Also check the exhaust pipe and manifold connections, as they do not always find their exact position until vibration has acted on them, and will need further tightening. This should be done with the engine stopped.

7. When warmed up to normal operating temperature, adjust the engine idle speed as described in Section 3.

8. Stop the engine, wait a few minutes to see if there is any lubricant or coolant leaking.

9. During the initial period of engine operation, the hydraulic valve lifters will be unusually noisy, but this noise should gradually disappear after a few kilometers.

10. After reaching operating temperature, stop the engine and tighten the cylinder head mounting bolts to the specified angle in the sequence shown in Figure 1.3. There is no need to re-tighten the bolts.

11. If many new internal components have been installed, it is a good idea to change the engine oil and oil filter after the first 1,000 km.
