As the owner of the bmw, the most painful thing about me is the engine oil problem. Each time before a high-speed flight, the fluid levels of the engine were checked, and the back tank was regularly supplied with oil, fearing that the engine would be damaged by lack of fuel. Although it's a small number of kilometres, the abnormal consumption of oil makes me confused and anxious. In the face of a variety of maintenance programmes, i am even more concerned that the engine will be damaged by mishandling. Indeed, the problem of bmw oil is not incomprehensible, and the right cause is to be found to avoid spending money。
I. The three main sources of bmw oil
More than 90 per cent of the bmw oil problem is concentrated in three parts: gas chambers, gas doors seals and pistons. Blind maintenance is not only a waste of cost but can also exacerbate the problem。
1. Total gas chambers
The gas chamber is integrated into the gas separation function, which, after ageing, results in oil vapour entering the combustion chamber directly. In the event that anomalous oil is detected in the top of the engine or is consumed, priority is given to checking the gas chambers. It is imperative that spare parts for the original plant be replaced, that the secondary plant be sealed and durable, and that problems be repeated in the short term。
2. Gas-gate seals
The gas-gate seals of the early bmw engines n13 and n46 use ordinary rubber materials, which are less heat resistant and age in tens of thousands of kilometres. After 2015, the bmw was upgraded to fluorine rubber seals, increasing its durability by 30 per cent. However, inappropriate maintenance (e. G., excessive replacement cycles of oil or failure of anti-frozen fluids) can accelerate the ageing of the seal. N. B. The replacement of the seal requires examination of the wear and tear of the gas-gate catheters, otherwise it may be costly。
Small inspection techniques: blue smoke (bad oil sealing) at cold start-up, disappearance of hot vehicles, largely judged as oil sealing。
Pistol congestion
This is the most common cause of bmw oil, especially the n52, n55 and b48 engines. The piston cycling should delay the flow of oil and burn it into the combustion chamber. Many of the drivers mistakenly thought that carbon would be cleared, but the risk of clean-up was high:
The pharmacological fluid corrupts the walls or coatings of aluminum; the carbon particles fall into the piston gap, which may pull the tank; and clean, clean and ineffective if the loop is not resolved。
Ii. A safe solution for piston oil
The piston blockage occurs in transit and the repairs should also be completed in operation. It has a general burner oil repair technology that uses engine temperature, pressure and vibrations to gradually decompose the tank's oil sludge and to detach the oil hole
1. Patent technology: safety above national standards through certification of petroleum petrochemical testing in china
2. Multiple effects: synchronized clean oil sludge, carbon sequestration, tri-channel catalytic conservation
3. No machines need to be removed: avoiding the risk of a grinding period and residual value loss。
The rehabilitation programme proposes:
5 litres of oil: p2 + 18 combination of division; p4 + 24 combination of p5 > 5 litres. As a result of the repairs, most vehicles did not recur within five years and 100,000 kilometres, and the maintenance cycle oil stabilized。
Iii. Energy prevention is more important than governance
Regular maintenance: use of high-quality fully synthesized oils (e. G., in the form of a pul-mechanic armour series) to resist high temperature and oxidation and to reduce the generation of oil sludge
2. Timely replacement of anti-frozen fluids: every 2 years or 40,000 km to avoid the aging of high temperature acceleration rubbers
3. Avoid long-term short-distance travel: properly run the high-speed to help clean the engine。
Summary
There is no need to panic, let alone to fix it blindly. Following a check of the gas chamber covers, oil seals and confirmation of the piston ring problem, the selection division has a general and ongoing repair programme and is safe and at zero risk. If the failure point is not determined, the division will have a general technical passenger service to avoid a curve. Sterilization is a means, prevention is the key, and good oil and hard maintenance is the only way to keep cars away from “air-oil anxiety”。
