Replacement of oil seals valves VAZ-2110 (8 valves) with their own hands: features of the work

If the engine started to "eat" the oil, then it doesdoes not mean that it's time to carry out major repairs. It is possible that the replacement of the VAZ-2110 valve seals is required. 8 valves in the gas distribution system, there are special oil-reflectors on them. They do not allow lubrication to get into the combustion chambers on the legs of the valves. And when oil seals are destroyed, oil begins to seep into the cylinders.

What are seals?

Made of rubber elements and necessary forIn order to remove oil from the legs of the valves. Moreover, rubber has high strength, is capable of withstanding high temperatures.

  5. Unscrew the two nuts with which the cover covering the camshaft is fixed.
  6. Install the distribution and crankshaft pulleys along the marks.
  7. Secure the camshaft pulley by inserting a piece of pipe into the slot. It is necessary that it is put on the stud in the cylinder head.
  8. Release the bolt that secures the camshaft pulley, using the spanner on the 17.

That's all, now the entire valve mechanism in front ofeyes. In the event that the work is carried out on the carburetor engine, it will be necessary to remove the pump (fuel) and the ignition distributor. Similarly, work is also being done to replace the guide valves.
