How Do Lifter Ticking Issues Affect Your BMW?

Posted on July 24, 2019 by smikyautomowp

BMWs are exceptional vehicles that offer outstanding performance while being safe and dependable. But just like all other vehicles, they have their own unique issues. BMWs that are equipped with the N52 engine are known to experience the dreaded lifter ticking issue. This problem is a major concern for drivers, and it is something that you should be aware of if your BMW has the N52 engine. In this article, we will discuss the lifter ticking issue and also where to go for help.

What is the N52 engine?

The N52 engine was a technological advancement that was ahead of its time. However, even though it was highly rated by drivers and car enthusiasts alike, it began to show signs of engineering and design defects shortly after it was released.

After driving their cars for a period of time, BMW drivers began to notice that their engine would become noisy under certain circumstances. The annoying ticking and rattling sounds were most prevalent in vehicles that had over 50,000 miles and during short drives around town in colder weather.

This issue didn’t only happen to drivers that didn’t take proper care of their vehicles. Even vehicles that were very well-kept experienced the rattling and ticking noises. This was extremely concerning for owners who took exceptional care of their BMWs.

What causes the ticking noise?

It wasn’t until recently that the N52 engine ticking noise was diagnosed, even though the issues were widespread and well-documented. After much investigation and diagnostics, the problem was narrowed down as the hydraulic valve lifter.

The hydraulic valve lifter is made up of 4 different parts, the body, check ball mechanism, plunger and socket. Its main function is creating the necessary space needed for other parts to expand and contract in the engine.

Symptoms of a Malfunctioning Hydraulic Valve Lifter

The main symptom of a faulty hydraulic valve lifter is the frustrating ticking noise. The noise is caused by the lack of adequate lubrication and happens more often when the temperatures outside are low.

There are other issues that can cause ticking and rattling noises. However, in BMWs that were manufactured between 2004 and 2015, the hydraulic valve lifter was the common source of the problem.

Possible Solutions

For a short period of time, BMW offered a remedy that included replacing the existing cylinder heads with a newer model. This was supposed to help take care of the lubrication problem, but in the end, it was in most cases, unsuccessful. Some repair shops were able to find a temporary solution that involved using a lighter weight oil.

Is it safe to drive your BMW with the lifter ticking issue?

There are no known issues that are attributed to the N52 lifter tick issue. Although you can continue to drive your BMW, it is not recommended. The noising drivers hear could come from a number of other engine problems, not just the lifter ticking issue. It is recommended that you have the symptom diagnosed by a trusted BMW specialist.
