BMW Cold Climate PCV Breather System Kit - 11617533400KT
Description
A comprehensive cold climate PCV kit for your M54B30 equipped BMW
This PCV kit features all of the cold climate version insulated hoses and valve. This system is standard on most vehicles sold in regions where it is significantly colder than normal. The idea of the insulation is to help prevent condensation inside the hoses from freezing and destroying the system inside out. BMW's breather systems have had this problem especially when the car is driven short distances in cold weather and is never allowed to reach operating temperature.
The plastic in these components deteriorates over time and eventually will crack or break. This will cause vacuum leaks and other detrimental issues which can cause engine damage and poor performance.
Note: This is approved for vehicles with Cold Climate Package. It can be installed on BMW's that don't have the cold climate package and this is often an upgrade over the standard system.
A PCV System, crankcase ventilation system or breather system is a system designed to release pressurized gasses from an engine in a controlled manner.
Breather System Kit Failure Symptoms- Illuminated oil pressure lamp. – Due to clogged oil suction strainer to oil pump or oil filter
- Illuminated Check Engine Lamp- Due to incorrect engine fuel trim level parameters
- Noise (whistling) – Noise due to high pressure in crankcase. This noise will stop if the oil filler cap is removed.
- Poor Drivability- Clogged crankcase ventilation can reduce the engine performance
- Uneven / Oscillating Idling- Caused by clogged crankcase ventilation
- Oil leak- From engine seals due to restricted crankcase ventilation
- Noise (knocking)- Low oil pressure can cause premature bearing wear and lead to internal engine component failure
- High oil consumption/noise from Turbo
- A damaged bearing or seal in the turbo due to lack of oil as a result of oil consumption.
