Today, I would like to first thank Mr. Yang's friends who have questions about the car side, and the first thing that comes to mind is solidity. See what a BMW needs to prepare after running about 200,000 kilometers?
The first is the valve four covers, and the oil leakage on the side of the valve four covers is basically caused by the aging and deformation of the valve four covers. Looking at this look, it seems that it has been replaced and replaced with a brand before, but it is not leaking or leaking oil, and it is a mess. Replace a set of original ones.
The second place where oil leaks is the oil, filter element holder and the last oil base. Although the gasket has been replaced, it still leaks oil, so it must be replaced with a Japanese one so that it is not prone to problems. When this is removed, you see that the rubber pads have shrunk, how can it be used? So this little money is not to be saved.
The third problem is that according to the owner's reaction water temperature, after inspection, not only the water pump has a fault code with a speed exceeding the tolerance range. 100% of the fault code is caused by the water pump.
The fourth problem is that there is jitter and vibration when the gear is engaged, and it is also the most recently replaced, and the rear axle inserter rubber sleeve looks like this.
The fifth problem is to find a more serious problem when removing the valve cover, that is, the chain guide is broken, and some of it has fallen into several inside, which is better than coincidental. If it is not in a unit period, it may cause more serious consequences. Look at what this plastic conduit looks like, is it crispy?
No matter what accessories are replaced with this cooling system, it must be suppressed and tested after replacement, which does not find water after pressure testing, and it is found that there is a leak in the water pipe above the cylinder head, and replace an aluminum Mickey Mouse connector on it, and the cost is only one-third of the original factory, and it is much more durable than the original factory, is it a good price?
If there is any problem with your BMW, you can talk about Lao Wu in the comment area, give you a quotation, and give you a reasonable price.
