Measure the pressure at idle speed at the warmed-up engine. This figure should be at least 0,08 MPa. Then swipe measurements when the vehicle is moving at a speed of 40 km/h, here the value should be about 0.2-0.25 MPa. Follow the pointer of pressure of oil, located on the instrument panel, if it shows that it is not correct, first check what oil you poured into the engine – whether the grade and quality.
Try replacing the sensor that indicates the pressure of the oil, it is often incorrect operation leads to a distortion of the data in the lubricating system of the engine that you see on the instrument panel. After replacing again check. If the pressure at the same low level, plug in the installation location of the indicator gauge control pressure gauge and use it to measure the pressure again.
Look at the pressure gauge. If it shows normal pressure, change the pressure gauge located on the dashboard. Buy a new one and install it.
Do a little pressure in the lubrication system of the engine can be due to clogged relief valve. So it needed cleaning. Gently remove it and rinse thoroughly. Not interfere with its adjustment, which guide after installing it on the engine. To do this, connect a test pressure gauge, and looking at his readings, adjust the valve.
The latest malfunction in which the pressure oil in the engines is negligible, could be a faulty oil pump that needs to be replaced. Also check strainer mosapramine, which may be dirty, then just clean it or buy a new one. Carefully inspect the liners connecting rod and main bearings that are on the crankshaft – excessive wear can also cause low pressure. After the replacement and cleaning of these sites, check readings, make sure that now with the oil all right, and the pressure at the proper level.
Advice 2 : How to increase the pressure in the engine
Insufficient pressure of oil in the engine – a serious chronic problem, difficult to eliminate and have critical consequences. The common cause is wear of bearings of the power unit, and especially the crank mechanism.
You will need
- - specialized oil pressure gauge
Primarily spend correct diagnosis of the fault and measuring oil pressure. The fact that the pressure sensors will be triggered when the pressure reached a critical level and it is too late to apply preventive measures. Sometimes the sensors are malfunctioning and should be checked regularly. Therefore, sensors believe with certain reservations.
Select and purchase the special tool to measure oil pressure, paying attention to the oil-petrol-resistant performance and an excellent range. Metering swipe through the threaded hole of the pressure sensor. A good instrument must have a complete set of adapters for all threaded connections. They are not cheap, like all professional equipment.
Technical characteristics of the engine determine the magnitude of the normal pressure of oil and the value of revolutions at which to perform measurements. If the rpm does not specify dimension spend idling at the operating temperature of the engine. If testing shows that when good parts of the lubrication system pressure oil close to the lower limit or below it, send the motor to overhaul.
If testing shows low pressure oil in the lower engine speed range, to increase to normal remove and check the regulator valve the oil pressure. At the lowered oil pressure in all ranges of operation of the motor first just try to fill it. If this does not help, remove the sump, clean the mesh of maslozavodska. Check the oil suction tube is damaged, replace.
If these measures do not increase the pressure to normal, check the oil pump. If it is defective or worn, replace. If all the parts of the lubrication system is in order, then, worn out bearings or engine bearings and requires substantial repairs. Wear liners indigenous or connecting rod journals requires a major overhaul. If they are not critical to normalize oil pressure engine handle the specialized protective and remedial preparation.
Applying additional additives to the oil, it is possible to achieve normalization of his blood pressure. Additive, creating additional film between the friction surfaces, often only create the illusion of a normal pressure in the lubrication system. When their excessive use decreasing lubrication of the crankshaft journals and bearings. This will lead to oil starvation and major repairs of the engine. Conclusion: do not get carried away with additives. This is a temporary measure that allows you to more safely operate the engine until it is repaired.
Advice 3 : How to raise oil pressure
What shows the sensor of pressure of oil, it is possible to understand how the car works correctly. Failures in the readings of the pressure sensor suggests that the machine appeared to malfunction. However, such disruption may have a few problems.
You will need
- control gauge;
- the sensor of pressure of oil;
- - the oil filter;
- - mineral oil;
- - the valves of the crankshaft.
Start the vehicle and drive some distance at speed 40 km/h At reduced pressure oil on the dash will light up a special sensor, which determines the normal performance.
Incorrect operation of the sensor of pressure of oil can cause you to see incorrect information on the engine oil system. So try first, replace the pressure sensor. After replacing measure whether his work standards, stated in the technical characteristics of the car.
The reason the pressure drops, the oil may be clogging the pressure reducing valve. In this case, it must be cleaned. Unscrew it, being careful not to damage, and rinse thoroughly. After installing the valve, adjust with a test pressure gauge.
Check to see if leaking under stuffing box gasket. This is a sign that the crankshaft is worn and must be replaced. If no leaks, but the gauge indicator shows a deviation, the reason lies in the deterioration or malfunction camshaft. Try to handle. Otherwise, the valves need to be replaced.
The reason for low pressure oil may be worn out filter. Replace the oil filter. Then check the quality of used oil. It is better to use mineral. Their thicker consistency will raise the pressure level to the required.
After replacement or adjustment of valves and gauges, be sure to check correctness of their work with a test gauge. At idle, the indicators should be at least 0,08 MPa.
Carefully read the information about the technical characteristics of your car. Design some machines it allows the blinking of the oil pressure sensor.
