A breather is a valve used to remove gases from the engine crankcase. It contains an oil trap and a dust filter, so it needs to be cleaned periodically.
Instructions
Step 1
Find the breather. To do this, lift the hood and find a square box there, to which two pipes fit: one goes from the mono-injector, and the other from the air purification filter. It may be located differently in different machines, but the essence remains the same.
Step 2
Remove the head of the air purification filter, which is popularly called air. De-energize the car beforehand - turn off the ignition and disconnect the negative terminal from the storage battery. Next, remove the intake manifold, which is located under the air, and you will see the breather you need, which is most likely attached to two bolts.
Step 3
Detach it and remove the cover. You will see the oil bump in front of you, tightened on a hairpin. Unscrew the nut on the stud using a long head, but do not remove it, because it is fixed with a special ring to the crankcase and it is impossible to put it back in the blind without removing the pallet. Clean the tube with a wire rod. Check the breather cap, clean the pipe inlet brush. The brush is used to extinguish the flame that forms with poor compression.
Step 4
After cleaning, a breather check is necessary, which is elementary. Start the engine and carefully remove the oil filler plug, and plug the neck itself with your palm. You should feel that there is no pressure. Ask the assistant to press the gas pedal, bring the number of revolutions to 3-4 thousand and again check with the palm of your hand if there is no pressure. In this case, a little pressure may occur. If the breather is clogged and cleaning does not work, then check the rings - they are stuck.
Step 5
Check the compression, which shows the state of wear of the rings, cylinders. Before checking, be sure to warm up the engine and connect the compressor. If the measured value is insufficient, measures must be taken to eliminate the cause.
