The 
MAN 51018105237 oil filler pipe is a vital component of the engine lubrication system. It directs oil into the engine crankcase, ensuring proper lubrication of engine components. This pipe is designed for use in MAN engines and is manufactured to exacting standards in Germany. Measuring 41 x 47 x 75 mm, this oil filler pipe provides a secure and reliable connection, contributing to optimal engine performance and longevity through consistent oil delivery and minimizing the risk of leaks or contamination.
Key Features & Benefits
This part is pretty straightforward. It's basically the tube you pour your engine oil into. It guides the oil down into the engine's oil pan, keeping everything lubricated. It also usually has a cap on top to keep dirt and debris from falling in. It’s not complex, but it needs to be solid.
Think of it as the entry point for lifeblood to your engine. Without it, you can’t properly maintain oil levels. It connects directly to the valve cover area, where you access it when you do an oil change. It isn’t something you interact with constantly, but it’s essential when you do need to add oil.
Symptoms, Risks & Replacements
It’s vital because if this pipe cracks or breaks, oil can leak out. You’ll notice if that happens, of course—you’ll see oil on the engine, and your oil pressure light will probably come on. A leak can quickly lead to major engine damage because oil is critical for reducing friction. Plus, if it's badly cracked, it can allow dirt and other contaminants to get into your engine, which is even worse. It’s one of those parts that isn’t expensive to replace, but can save you a lot of money in the long run if you catch a problem early. You can find these pretty easily at places like Fixparts Online, and they’re usually a pretty simple DIY job if you’re comfortable doing basic engine bay work.
