Replacing the oilmaging caps, how to replace the oilmaging cap without removing the head of the cylinder block

Outlooking caps (that is, valve seals) perform a fairly important function in the gas distribution mechanism of the car. They remove excess lubricant from the valve rods in the process of their movement, and also do not allow foreign substances into the combustion chamber. If the oil slimming caps wear out, it is extremely important to replace them in a timely manner, in order to avoid increased oil consumption, as well as the appearance of Nagara on the mechanisms and parts of the vehicle. About this further in the article.

Masciling caps, device, principle of operation, purpose

The non-stop work of the mechanisms in the process of movement of the vehicle implies the presence of a sufficient amount of lubricant in the mechanism of gas distribution, which must mitigate the friction of parts, however, along with it, should not penetrate the combustion chamber. For this, it is necessary for the scale caps that remove excess oil when the valves are operated, and also serve as a flap, which prevents the ingress of the lubricant inside the chamber.

The oil surcharge caps consist of three components:

  1. The reinforced steel sleeve, serving the base of the cap and gives it strength.
  2. Rubber cap shooting oil surplus from valve rod.
  3. Spender spring, providing a dense adjoining of the rubber cap to the rod.

In contrast to the oil-saw caps of an old sample made from a sprocket, to date, the rubber part of the oil surcharge cap is produced from the secondary or acrylate rubber. The use of modern materials has significantly extended the life of these items, but still sometimes they may come into disrepair and demand replacement.

Occupal caps, signs of wear

An experienced auto owner may assume aging or wear of oil surcharge caps in the event of the following signs:

  1. Increase oil consumption.
  2. The appearance of nagar on the ignition candlelight.
  3. The appearance of blue or sizogo smoke from the exhaust pipe.

Noticing such alarming signs, the car enthusiast should inspect the gas distribution mechanism, the oil-free caps and valves, and if its speculation was justified, immediately replaced the damaged parts, without waiting for more serious consequences.

To the serious consequences of lubrication intake, combustion chamber include:

  1. Reducing the power of the power unit.
  2. Bad closing valves.
  3. Fall compression.
  4. The appearance of nagar in cylinders and pistons.
  5. Idling car starts to getting up.

Nagar on aggregates and vehicle mechanisms accelerates their wear, which can entail a premature major overhaul of the engine, so do not pull with the replacement of oil-challenged caps, if they wear out.

Replacing the oilmaging caps with their own hands without removing the head of the cylinders (step by step instruction)

The replacement of spoiled caps can be made or dismantling the head of the cylinder block, or without dismantling. As a rule, the replacement of the oil-free cap without disassembling the head is made when the wear of the elements was detected in a timely manner, and at the valves and pistons did not have time to form a decent nagar. Otherwise, you have to remove the GBC, clean the nap and customize the operation of the gas distribution mechanism.

removing the exhausted oiling cap

  1. First, remove the lid of the gas distribution mechanism.
  2. Next, exhibit distribution and crankshafts by tags. We put on the elements the appropriate marks so that after the repair does not arise difficulties with their exhibition. Record the location of dismantled nozzles and connectors.

  3. Removing the camshaft, it is necessary to loosen the tensioner of its drive.
  4. In case the drive is the chain, you need to unscrew the drive gear and remove it from the camshaft. It is advisable to remove the key from the shaft groove and remove it to not lose. If the drive belt, it is easier to dismantle the belt from the gear.

  5. Then we turn the fastening bed of the camshaft and remove it from the head. While the camshaft is removed, check it on cams and shekes.

  6. Remove the valve pushers - depending on the design, you need to dismiss the rocker or remove the glasses with hydrocomathers.

  7. Since the pistons of the first and fourth cylinders are already standing in the upper dead point, it is better to start a replacement from the edges, because it is necessary to dry out the valve so that he rests on something. In this case, this is the bottom of the piston.

  8. In some models of car, the intake manifold interferes so much that it is necessary to shorten the calcifier, as it is easier to do it, rather dismantle the collector.

  9. Take the dismissaler. His bracket, which is attached closer to the end of the lever, it is necessary to fix the bed on the fastening stiletto, and the one that is attached closer to the middle, you need to put the ring on a plate that covers the valve springs. Next with one hand click on the dismumbering lever to compress the valve springs and omitting the plate down in the rod, the second hand takes the tweezers and take off the crackers from the plate.

  10. We remove to the side of the silent, after which we remove the plate and both springs from the stock.
  11. Next you need to fix on the caps of the capture cramp. Having moved the ship to the puller rod up, you need to hit them along the top up - dismantling of the unsuccessful cap is made.

  12. While the valve is free, it is necessary to check the wear of its guide and rod. To do this, you need to take the top of the rod with your fingers and try to shake it. In case of insignificant wear, it will not be possible for you because the backlash will be absent.

installing a new oilmaging cap

  1. Remove the springs from the glands.
    img_7080_1
  2. We insert the gland and drip on the valve rod of the oil.
    img_7080_1
  3. After that, on the valve stem, we put a gland with a mandrel and shift it down at least before the direction of the guide. Then you do not hear the hammer on the mandrel than we press the gland on the landing place.

  4. Before assembly, do not forget to put on the springs on the hosted caps.

  5. Next, install the components of the valves and drummer the method used to dismantle the crackers.
    img_7080_1
  6. We repeat this sequence as much time as it is necessary.

  7. Collect disassembled nodes in reverse sequence. If the hydraulic components in your engine do not apply, adjust the valve.

Tips Profi: Do I need to use chemical additives to restore seals

As you know, in our time there are quite a few additives for the restoration of the seals. If you have a temptation to take advantage of them instead of replacing the cap, remember that the miracles in the work of the power unit does not happen. Stop natural wear item is impossible. Such additives are able to soften hardened rubber, which would seem to restore the properties of the glands. But, as experience shows, they or in no way affect the rubber, or soften it very much, from which the size of the working edge increases and the oil consumption increases significantly. So it is better to replace the oil-giving caps. The cost of this event will depend on the type of motor. However, you will know exactly what they perform their functions. Additives, alas, will not be able to guarantee such an effect. Therefore, you should not try such additives on your car.
