11151708801 BMW HOSE

This hose really does one main thing – it vents crankcase pressure. Basically, when your engine runs, some combustion gases get past the piston rings. It’s normal, happens in any engine. This hose provides a pathway for those gases to escape, preventing pressure build – up inside the engine. It also carries oil mist away from those gases. It connects different parts of your engine’s ventilation system, typically from the valve cover to the intake manifold or air cleaner. Think of it as a little pathway, making sure everything breathes properly. It’s a small part, but it's connected to some bigger stuff, so a failing hose can affect how smoothly your engine runs. If this hose fails, that crankcase pressure builds up. That can lead to oil leaks, because the pressure has to go somewhere. It can also push oil past your valve seals, leading to burning oil and blue smoke from your exhaust. You’ll notice if it gets really bad – likely oil all over the engine, or a noticeable burning smell. It’s a relatively cheap part to replace, and avoiding bigger issues down the road is always smart. You can often find a good replacement on sites like Fixparts Online. It’s definitely one of those things where a little preventative maintenance goes a long way.
