1.9. Hydraulic compensators of gaps of valves of the engine of 1,6 l

 PERFORMANCE ORDER

  1. While the hydraulic compensator of gaps of valves is installed in a head of cylinders, press it with the maximum force in the place where the camshaft contacts with the gap compensator. If the compensator of gaps is serviceable, it will move down with great difficulty.
  1. If when pressing the compensator of gaps easily moves down, it is faulty and is subject to replacement. Fill the hydraulic compensator of gaps of valves with engine oil, you hold vertically and fingers of a hand squeeze it from two parties.

The main malfunctions of hydraulic compensators of gaps of valves, the reasons and methods of elimination are given in the table.

Malfunction
Possible reasons
Elimination method
• Temporary noise at start of the cold engine Normal phenomenon Noise disappears after warming up of engine oil and achievement of normal pressure
• Continuous noise after the engine was not started within 48 hours Oil from cameras of hydraulic compensators of gaps of valves flowed out and air got to them Noise will disappear in 15 min. operation of the engine when the bent shaft of the engine reaches the frequency of rotation of 2000-3000 min.-1


Do not increase the frequency of rotation of a bent shaft of the engine higher than 3000 min.-1 as it is possible to damage hydraulic compensators of gaps of valves.

• Continuous noise after launch of the engine and replacement of a head of cylinders There is not enough oil in oil channels of the engine
• Continuous noise after long launch of the engine a starter or by method of towage Oil from cameras of hydraulic compensators of gaps of valves flowed out and air got to them
• Continuous noise, after replacement of hydraulic compensators of gaps of valves
• Continuous noise, at an idling frequency after the movement at a high speed Level of engine oil too low or too high Check the level of engine oil
A large amount of air is dissolved in oil after the high frequency of rotation Check system of supply of oil
Deterioration in properties of engine oil Check quality of oil and, if necessary, replace it
• Noise continues more than 15 min. Low pressure in the lubrication system Check quality of oil and, if necessary, replace it
Hydraulic compensators of gaps of valves are faulty Remove a head of cylinders and, pressing hydraulic compensators of gaps of valves, check the size of their compression
