The first start of the engine after capital repairs

At the first start of the engine after its capital repairs it is necessary to have near at hand the fire extinguisher.


 PERFORMANCE ORDER

  1. After the engine is installed in the car, check levels of motive oil and a cooler.
  2. At the removed spark plugs and the ignition which is temporarily put out of action (The section Check of Compression Pressure in cylinders) turn the engine for rise in pressure of the oil confirmed by indications of the measuring instrument or switching off of a control lamp.
  3. Establish spark plugs, connect to them candle wires and put into operation system of ignition (The section Check of Compression Pressure in cylinders).
  4. Start the engine. Some time for rise in pressure in a power supply system can be required, however start should not cause special difficulties.

In case of cottons in the carburetor or the case of a throttle, double-check installations of gas distribution and a corner of an advancing of ignition.

  1. After start of the engine it is necessary to wait for warming up it up to the normal working temperature. Do not allow increase in frequency of rotation of the engine above turns of bystry idling until are pumped over and silently hydraulic pushers (about five minutes) will not begin to work.
  2. While the engine is warmed, carefully check it for existence of signs of leak of fuel, oil and cooler. If in the course of capital repairs the new camshaft and pushers were installed, the engine has to work on single turns not less than 15 minutes (you monitor indications of the measuring instrument of temperature - it is necessary for extra earnings of cams and pushers.
  3. Kill the engine and repeat checks of levels of oil and a cooler.
  4. Go on the car to the area with weak traffic and disperse it at completely open butterfly valve from the speed of 50 km/h (30 miles/hour) to the speed of 80 km/h (50 miles/h), then again dump speed to 50 km/h, having closed the gate (having dumped gas). Repeat the procedure 10 - 12 times. It will provide shrinkage of piston rings and correct to their extra earnings to walls of cylinders. Again make sure of lack of leak of oil and a cooler.
  5. The first 800 km (500 miles) of a run as often as possible check the level of motive oil and try not to accelerate the car to high speeds. The moderate consumption of oil at a running in of the engine is the normal phenomenon.
  6. After about 3200 km (2000 miles) of a run replace motive oil and an oil filter.
  7. The following several hundreds of kilometers/miles operate the car in the usual mode. Do not try to spare the engine, but also do not overload it.
  8. Later 3200 km (2000 miles) of a run replace motive oil and an oil filter again and you can consider the engine rolled.
