A BMW MINIR56 in Chengdu drivers burned serious oil. At the same time, the vehicle was also accompanied by acceleration weakness and cold vehicle shake. After inspection, it was found that the ECU recorded a camshaft adjustment failure. After maintenance, the fault point was locked on the adjustment solenoid valve. The solenoid valve stuck causes inflexible adjustment, unstable idle speed and vehicle shake. Just replace it. Next, if you repair the oil burning, you will replace the valve oil seals with ease. Changing the oil seals can basically solve the problem of most of the oil burning, but for some cars, simply changing the oil seals cannot cure the problem. There are prerequisites.
The feedback from riders after the repair was good. There were no abnormalities for the time being.
It is this MINI that burns oil badly, has smelly exhaust gas, and is unstable at idle speed.
The computer diagnoses the fault record, and it is necessary to read the fault code before maintenance. Through the fault code, we can find some maintenance ideas.
It takes most of a day to complete the oil seal of the ventilation valve.
To replace the oil seal, you need to remove all accessories on the cylinder head.
Hydraulic tappet rocker arms and other parts are placed in an orderly manner for easy installation, and it is best not to place parts with tolerances in the wrong position.
Compared with old and new oil seals, the old oil seals have almost no elasticity due to carbonization, so they are prone to burning oil.
Changing the oil seal requires the use of some tools to easily replace the parts we need to replace.
After repairing this car, I found that the previous owner didn’t take much care of the car, at least it was not maintained very well. No matter how good the appearance is, but the inside is not good and it is not fun to drive. The MINI is for driving and playing. If you want to play, you have to have fun. Small changes are fun. What sports switches, paddles and so on.
The final step inside the machine after installing each part requires checking the timing, and timing is very important.
Bikers said that the idling speed is weak, shaking and accelerating. The fault point of this car is here. The solenoid valve is stuck, so just replace it. The same problem does not necessarily mean that the same part is broken.
Replace it with a new valve chamber cushion. Dana and Aier Bell are of good quality. Even if you don’t lack money, you can also buy original parts
Each bolt has a corresponding torque, and the bolt length, size, and strength are different.
There were no abnormalities in the test run, so the cabin was cleaned and the work was completed.
