- on C-engine (1.4 l) gases are vented from the cylinder head through a calibrated port and T-piece directly into the intake manifold and into the suction funnel or injection system.
- on F-engines (1.7-/1.8 L 16-valve and diesel) The gases are removed by a closed exhaust system through an oil separator in the engine housing. Depending on the degree of vacuum, the gases enter the cylinders through the air filter or directly through the intake manifold. Additionally, the venting system on the F-engine is connected to the tank vent.
Cleaning the engine ventilation system
1. Disassemble the intake mufflers and check if the intake port of the vent hose is dirty.
2. Dismantle the hoses and clean with gasoline; replace if necessary.
3. Depending on the type of motor, disassemble the adapter in the motor housing and clean it of dirt.
4. Depending on the type of engine, clean the oil separator and dry it thoroughly before installation.
5. If the channels of the oil separator are dirty, replace it.
Note. Recommendation: If the engine emits oil vapors with the vent hose removed or the oil filler cap removed, this means that the pistons and cylinders are badly worn.
If the engine ventilation ducts are heavily soiled and the inserts (arrows on the left figure) and oil separator (drawing on the right) clogged with oil residue, this will adversely affect the condition of the engine. Do not attempt to clear the calibrated through holes of the conductive inserts with a drill. This can lead to a violation of the ventilation of the engine. Despite the different device, the principle of operation of ventilation on all engines is similar.
