BMW X5 PCV Valves & Hoses

Replacement of a Positive Ventilation Crankcase valve/hose assembly on a 2014 BMW X5 Xdrive50i (F15 / N63) 4.4L Twin Turbo. These hose assemblies become very brittle over time due to engine heat exposure. If Your vehicle is older and has never had them replaced, now may be the time. Just a tip; if they are original, simply touching them to see if they are okay, may cause them to break. Proceed with caution.
