Timing belts are essential, but unless specifically stated otherwise, there is no need to replace them frequently.

Timing chains, in my opinion, can endure twice as many miles as your automobile now has. or perhaps more. 150 to 200 miles.
You may alter the chain tensioner on the N54. It just screws in from the engine’s side. driver’s side of the front. And works like a hydraulic cylinder applying pressure to the chain guide rail. Oil passageways can clog up since they are quite small.
To achieve it, the coolant tank has to be removed. In addition, just screw the new one in and tighten it to specifications, and you’re done. NEVER do that while starting the engine.
What you have for an engine determines. Timing chain kits for the N20 2L engine in the 18i, 20i, and 28i are quite flimsy.
Mine stopped working in February after 70k miles. After spending several hours doing research, I took the engine off and fixed it myself because I have some basic mechanical expertise.
I spent around PS900 on parts purchased directly from BMW and online timing tools.
Do BMWs use timing chains or belts?
So what distinguishes a timing chain from a timing belt? Both a timing chain and belt perform the same basic function. These mechanisms are created to maintain the relative position of the valves opening and closing to the position of the piston as the engine is running, regardless of whether you drive a Porsche, Mercedes Benz, or BMW with an internal timing chain, or an Audi or Volkswagen with an external timing belt. When a valve is opened at the incorrect time, it may come into contact with the piston and cause a catastrophic engine failure.
The piston will raise (building compression) and the valves will open precisely, allowing air and fuel to enter the combustion chamber and exhaust to depart in less than one thousandth of a second in an engine with perfectly timed ignition. When valves open or close prematurely or lately due to a timing issue, the piston will be driven into the valve, most frequently bending the valve and possibly punching a hole in the piston crown, rendering the engine worthless. These fixes could cost as little as $4,000 to $5,000 or, depending on the engine, much more.
An internal timing chain is used by brands including Porsche, BMW, and Mercedes-Benz. These chains are stronger and less prone to break on their own. The same outcome is more frequently experienced when other chain-holding components, including chain tensioners and chain guides, fail. Check engine lights and a rattling sound, which is typically heard while starting an engine, are early warning indicators of a breakdown.
Initially using timing chains, Audi and Volkswagen switched to an external timing belt in the 1980s, 1990s, and the majority of the 2000s (now returning to chain drive systems). The timing belt is simpler to inspect and replace than the timing chain. Timing belt replacement often costs between $700 and $900, which is significantly less than timing chain replacement. On most models, this cost also includes the water pump. The external timing belt’s drawback is that, like all belts, it eventually wears out and needs to be replaced. Timing belts should typically be changed every 80,000 miles, or every five years. Each time they are serviced or at least once a year, these should be visually inspected.

Are new BMW timing chains required?
Almost all of the engine models made by BMW use timing chains. It is advised to replace your timing chain before it breaks since internal engine damage could result in very expensive repair costs if you wait. These timing chains typically last nine years or 90,000 kilometers.
Which model year BMW timing chain issues?
The BMW 1-Series, 3-Series, and 5-Series vehicles manufactured between 2007 and 2009 have seen multiple instances of complete engine failure in the past year, according to Watchdog. The engine came to a complete stop as a result of the timing chains snapping, which was the cause of the problem.

All of the moving components of an engine that cooperate to propel a car forward are connected by the timing chain. They must all function flawlessly together.
The N47 engine has a secret timing chain link at the back that engineers claim is a component of the engine that is meant to endure the lifetime of the vehicle and is thus never maintained.
However, if the timing chain malfunctions, a catastrophic engine failure might occur suddenly.
It’s difficult to correct. Drivers must at the absolute least replace the chain, but it’s more likely that a completely new engine, which may cost anywhere from PS500 and PS8,000, needs to be installed.
In 2011, Dan Greenwood purchased a pre-owned BMW 3-Series 320D. Despite having traveled almost 100,000 kilometers, it had a complete service history. The BMW name and the knowledge of the car’s past offered him assurance that he was making a reliable purchase.
The engine abruptly shut off while he and his young girls were traveling in slow traffic. He was informed that he would require a complete engine rebuild that would cost more than PS2,000 after being transported to a local mechanic where they looked at his car.
The automobile is no longer under warranty because it is five years old, so Mr. Greenwood said, “I was just surprised. I was looking at something that would cost thousands of pounds from what appeared like a simple mistake.”
How much does a BMW timing belt replacement cost?
Belts don’t cost a much by themselves. Since many pieces must be removed in order to reach the belt, labor is where the true expense lies. Your best chance is to shop about and compare prices, but be prepared to pay anything between $409 and $919. (including parts and labor)
How long is the lifespan of a BMW timing belt?
Although they can last up to 100,000 miles, it’s always a good idea to change them before that. The engine’s valves, pistons, and other internal components may suffer severe damage as a result of belt failure.
Which BMW engines experience timing chain problems?
severe issues with BMW engines BMW engines have experienced a variety of problems, including a timing chain issue. Some models of the BMW 320d 2.0 Diesel, 520D 2.0 Diesel, and X5 330D 3.0 Diesel have been known to experience these problems.
How many miles is a timing chain for a BMW good for?
The second is the 4-cylinder, normally aspirated and turbocharged petrol N12, N14, and later N16, N18 engine that was installed in the MINI Cooper and S models from 2006 to 2016.
Often, if the timing is allowed to jump too late, the exhaust valves will flex. Therefore, if the engine rattles after starting from cold, it is preferable to replace.
Due to damaged valve stem seals that allow engine oil to vacuum bypass into the cylinders, these engines are also vulnerable to excessive engine oil consumption. It is advised to replace the valve stem seals when the engine is disassembled to replace the timing chain. This will spare labor for this separate repair down the road. We have a unique tool that makes it possible to repair the valve stem seals without taking the cylinder head off.
The drive belt for the alternator may occasionally be cracked or worn out from aging. While this is being removed, it is advised that you replace it.
In some circumstances, we demand a labor deposit to reserve a timing chain replacement (often roughly 50% of the entire repair cost). This is because there have been so many appointments in the past that were cancelled or missed.
How can I tell if my BMW’s timing chain is damaged?
As the timing chain ages and becomes increasingly worn, its symptoms frequently appear gradually. Therefore, you generally won’t have a significant acute symptom until the chain is just close to fail completely. Instead, think about how your car is operating right now and attempt to remember how it was operating a few months ago. Small issues can be a sign that the chain will eventually fail completely.
Here are some signs that your timing chain may be failing:
- Rough idling: Start the engine of your car and drive away. The timing chain may be wearing out if it is shaking or vibrating more than usual. Of course, there are other issues that could result in harsh idling, but it’s always worthwhile to investigate the issue since it usually gets worse over time.
- Unusual noises: You might hear your engine rattle, not just when it’s idle but also at other times. The timing chain may be loose and banging against something else if the sound is unchanging and coarse.
- The timing chain will eventually wear down because of metal particles in the lubricant. Metal shavings may begin to emit when it reaches the end of its useful life. If that happens, it will go into your engine oil, which can lead to other issues. However, metal shavings can be produced by any part of your vehicle that is deteriorating, so it’s important to look into the issue before replacing the chain.
- Engine problems: If your BMW won’t start, the chai may be damaged and not supplying enough pressure to start the engine. If the chain snaps while you are driving, the timing chain may have snapped at that same instant. If this occurs, your car may suffer extra damage from the belt issue or the piston damage.
- Engine misfires: Your engine may misfire before the chain has completely snapped. The crankshaft and cam are connected by a chain. The chain can cause the car to skip a gear on the crankshaft or camshaft if it is overstretched. This will put further strain on it, and eventually it will break.
- the check engine light is on The check engine light could, of course, indicate a wide range of issues with your BMW. However, there is a chance that the timing chain has failed or is soon to fail.
It is advised to bring your BMW in if you experience any of these symptoms so that a mechanic can examine your timing chain and any other potential issues.
What occurs if the BMW timing chain snaps?
An engine with a broken timing chain will either not start or fail while being driven. The engine won’t start if the belt is already broken since there won’t be adequate compression. The pistons will sustain damage by coming into touch with the valves if it breaks or leaps while being driven. The actual valves will flex, possibly ruining the engine.
