Emissions System for BMW Z3 (1996-2002)

The factory rubber/plastic hoses become brittle and crack over time. Brittle and cracked hoses can cause multiple vacuum leaks that are impossible to repair without hose replacement. Vacuum leaks can cause many problems including rough running, missing, stalling at idle, and even a no-start condition.

The factory hoses offered through BMW are plastic and will yield the same results of becoming brittle and damaged over time. Our solution is a premium replacement that will outlast everyone of the OEM replacements. Our Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

CSL Vent Hose (11157833649) - Silicone Crankcase Vent hose is a direct replacement

Key benefits:

Lifetime replacement of the brittle OEM plastic crankcase breather hose that is susceptible to cracking overtime from constant heat cycling

Design:

Retains OEM hose end fittings to ensure proper seal

When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system  baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.

Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

Features:

• 6061-T6 billet machined body, anodized black for lasting protection and appearance
• Strategically positioned 4 chamber baffle system maximizes oil / air separation 
• Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
• Sealed with a pre-installed viton O-Ring
• Includes 2.5mm allen key to remove baffle plates for cleaning
• Engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can
• Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
• Optional use drain hole - drain kit included!
• Universal mounting kit

Our engineers at Turner sought out to solve the degrading issues that happens with the factory crankcase vent hose and found the best solution is a silicone replacement. Our Turner Silicone Crankcase Vent Hose can be used to replace the factory brittle hose to prevent vacuum leaks and lackluster performance. Simply take your factory crankcase vent hose and remove the ends; the factory ends can be installed on the new Silicone Vent Hose with the supplied clamps for a tight seal.

Rubber breather pipes in various BMW applications are susceptible to cracking. Over time, engine heat and weather conditions can weaken these hoses, leading to breaks or leaks. This results in significant vacuum leaks that can severely affect engine performance.

Moreover, BMW faces a problem with oil separators freezing in cold weather, particularly if the engine isn't adequately warmed up during driving. Typical signs include a howling noise and subsequent oil leaks.

This is the BMW crankcase return line that goes from the intake manifold to the top CCV connecting hose. We also offer a complete CCV repair kit
