What's the Difference Between OM617 and OM606 Mercedes Benz Injectors?

 

The most common question about Mercedes Benz OM617 and OM606 injectors is which ones should I buy? The reality, however, is that there's no clear-cut answer that applies to everyone. Therefore, this article will explore the differences between the two types of injectors, so you can decide which one(s) are right for your Mercedes diesel vehicle or commercial truck application. But first, some background on each type of injector...

OMinjectors vs injectors

What is the difference between OEM injectors and aftermarket ones? The terms OMinjector, OMinjecotr, OM601-605 injector, OD356-393 & OM611-615 Injector are thrown around like they're all interchangeable. That's not necessarily true. OE (original equipment) and aftermarket parts aren't always an exact match.

How to choose the right injector for your car

When it comes to injectors, there are two different types you'll come across—the older but reliable OM617 injector and its more advanced successor, known as OM606. As a result, there's a lot of confusion regarding which type of injector is best for your car. Unfortunately, it's not quite that simple; both types have their advantages over one another.

How do om606 injectors and om617 injectors differ from each other

Many people wonder, How do om606 injectors and om617 injectors differ? These two engines have a few major differences. First, both of these diesel engines are in vehicles built by Mercedes-Benz. However, they aren't found in all vehicles that the manufacturer makes. The biggest difference is their cylinder displacement size: A 617 has a smaller motor than a 606, with five cylinders rather than six.

When to replace your Mercedes Benz injector

The original style om617 injector is designed to withstand a lot of stress. It can take years of use before they begin to break down, but it will be more apparent than you would like when they do. Common symptoms of a failing injection system are lack of power, black smoke from your exhaust, and difficulty starting your car. When these things start happening, it's time to check your injection system for damage.

How do you fix leaking om606 injectors or om617 injectors?

The first thing you must do is check your engine oil. If your engine has lost motor oil, you leak one of your seals or gaskets. If you find that your engine has lost motor oil and there are no signs of leaks visually, then your most likely culprit is a broken seal inside an injector nozzle or cylinder head. You can often hear or feel an audible tick from these leaks, but again because they are small, visual signs may not be obvious.
