2007 BMW 335i N54 Crankcase Vent Hose Replacement

I'm replacing the crankcase vent hose on a 2007 BMW 335i with the N54 engine. If you're chasing a brittle breather connection or need to get familiar with the hose routing, this video stays focused on that piece of the crankcase-ventilation system.

What you’ll see in this one

BMW vent hoses often get discussed alongside PCV repairs, but the hoses and internal valve system are not the same component. Check the exact routing for your N54.

A closer look at this job

The N54 crankcase breather hose is the subject of this 2007 BMW 335i project. The hose is part of the engine's crankcase-ventilation plumbing and is commonly searched as a PCV hose, CCV hose or breather line. Those names overlap, but may describe different components on other engines. Watch to identify the hose location and replacement work, and compare the routing and connectors with your particular N54 installation. This recording does not establish the cause of every crankcase-pressure or vacuum complaint.
