What is the effect of leaking valve chamber cover pad?
Valve chamber cover replacement precautions:
First, be sure to use the original valve chamber cover
Replacing the original valve chamber cover will solve the problem. The original Peugeot Citroen valve chamber was made by Mega, and this is its part number. There are a lot of parallel goods on the market, and 95% of the quality is very water, if you do not have a reliable channel procurement, the probability of buying a parallel valve room cover is as high as 95%. Once you get a horizontal valve cover, there is a large probability that it is not good to use, and there are many safety hazards, such as the engine idling for an hour, the valve cover is not leaking, the engine climbs a steep slope, and the accelerator is pressed, when the negative pressure is large, the oil will leak out from the valve cover pad. When the engine oil in the cabin is more serious, it flows to the exhaust manifold below, and it is easy to cause an engine fire under the high temperature of more than 400 degrees in the exhaust manifold, and the potential safety hazards are great. Some people replace the aluminum alloy cover, the aluminum alloy cover is not the original factory is not good to use, because when the valve is installed, the plastic is tense, the aluminum alloy is not a little tension, and the phenomenon of oil leakage will occur for a period of time. Of course, the original factory is aluminum alloy, we must change the original aluminum alloy lid, the original factory is plastic, we must change the original plastic lid.
Second, how to identify the original valve chamber cover
It is very difficult to distinguish only by looking at the valve chamber cover. First, look at the internal situation of the valve chamber cover that has been aged and damaged: the red spot of the valve chamber cover that has been removed has been damaged and fallen off, resulting in serious oil burning. Look at the two new valve chamber covers how to distinguish between good and bad, the easiest way to compare the glue at the seams, the glue at the brand parts, and the seams at the original factory Meijia. The glue seams of brand parts are rough, visible to the naked eye, and the glue of the original parts is very uniform and neat. The glue at the seal under the oil cap is also very different from the glue on the left of the brand part and the glue on the right of the original valve chamber cover. So if you want to change, just change the original parts. Third, the replacement of 1.6T valve chamber cover precautions Many riders have encountered the valve chamber cover oil leakage or valve aging in the valve chamber cover burning oil problems. After the replacement did not solve the problem, in fact, it is three reasons, remember the following three points, replace the valve chamber cover does not detente. First, the original valve chamber cover, which is an essential element; The second point, after opening the valve chamber cover, the cooling time should be enough, the third point, according to the standard torque, in order to install the screws, as long as the above three points, can be a good solution to the problem, the valve chamber cover problem is not a design defect.
Fourth, we pay most attention to the negative pressure value
The negative pressure of 1.6T engine is relatively unfamiliar to many people, and we will provide this value to you today to facilitate the inspection of oil burning in the future. First of all, there is a tool to test the negative pressure value, after the hot car, detect the negative pressure value, insert one end of the hose into the filling port of the oil gauge, and set the other end as mbar unit, you can start to test. 1.6T normal value around 35 there is a slight change, if less than 25 will obviously begin to consume oil, at this time the use of traditional methods to open the oil cap pull out the oil gauge is not observed, almost can be close to 3000-4000 kilometers a liter of oil consumption. If it is lower than 12, there will be obvious abnormal oil consumption, and the consumption of a liter of oil for several hundred kilometers or one thousand kilometers is commonplace. Especially when the initial valve chamber cover is aging, the oil consumption in low speed driving in the city is not obvious, and the oil consumption in high speed driving will be obvious.
