Petrol engine models
2. Remove the spark plugs. On models with a distributor, disable the ignition system by disconnecting the ignition HT coil lead from the distributor cap, and earthing it on the cylinder block. Use a jumper lead or similar wire to make a good connection. On models with a static (distributorless) ignition system, disable the ignition system by disconnecting the LT wiring connector from the ignition HT coil, referring to Chapter 5B for further information.
3. Turn the engine on the starter until the oil pressure warning light goes out. Refit the spark plugs and reconnect the spark plug (HT) leads, referring to Chapter 1A for further information. Reconnect any HT leads or wiring which was disconnected in paragraph 2.
Diesel engine models
4. Disconnect the wiring from the stop solenoid on the injection pump (see Chapter 4D), then turn the engine on the starter motor until the oil pressure warning light goes out Reconnect the wire to the stop solenoid.
5. Prime the fuel system as described in Chapter 4D.
6. Fuliy depress the accelerator pedal, turn the ignition key to position "M", and wait for the preheating warning light to go out.
All models
7. Start the engine, noting that this may take a little longer than usual, due to the fuel system components having been disturbed.
8. While the engine is idling, check for fuel, water and oil leaks. Don't be alarmed if there are some odd smells and smoke from parts getting hot and burning off oil deposits.
9. Assuming all is well, keep the engine idling until hot water is felt circulating through the top hose, then switch off the engine.
10. Check the ignition timing (petrol engines) or injection pump timing (diesel engines), and the idle speed settings (as appropriate), then switch the engine off.

11. After a few minutes, recheck the oil and coolant levels as described in "Weekly checks", and top-up as necessary.
12. If they were tightened as described, there is no need to re-tighten the cylinder head bolts once the engine has first run after reassembly.
13. If new pistons, rings or crankshaft bearings have been fitted, the engine must be treated as new, and run-in for the first 500 miles (800 km). Do not operate the engine at full-throttle, or allow it to labour at low engine speeds in any gear. It is recommended that the oil and filter be changed at the end of this period.
