BMW Engine Parts for BMW E46 M3 S54 (1999-2005)

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.

Turner Silicone Crankcase Vent Hose replaces the following part #'s:

CSL Vent Hose (11157833649) - Silicone Crankcase Vent hose is a direct replacement
Non-CSL Vent Hose(11157831311) - Silicone hose will make a "U" bend with direct fitment and can also be trimmed for your own preferable fit.

- Key benefits:

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

Turner logo forward facing when hood is open
Retains OEM hose end fittings to ensure proper seal and reduce cost
“Black” 3 ply reinforced silicone w/ “White” Turner logo
includes 2 German style 430 stainless worm-drive clamps for installation
- Special care instructions:

Do not overtighten hose clamps, hand tight is recommended.
Carefully cut the OEM plastic casing from both plastic fittings for reuse

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 hole can be used 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 (valve and hose sold separately, watch for our model specific drain kits!)

A combination of billet fittings and AN lines for an upgraded and serviceable crankcase vent hose. Attaches between the oil separator and the CSL air box.

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.

We have created a full motorsport style solution with our CSL Crankcase made from machined 6061 billet aluminum with AN style fittings and nylon fiber braided lines. This is a fully serviceable replacement that will outlast every one of the OEM replacements. Our AN crankcase line can be used to replace the factory brittle hose to ensure your S54 is free from vacuum leaks and performing properly.

Unlock the full potential of your S54’s valvetrain with our High Performance Cam Followers/Rocker Arms, built for precision, durability, and reliability in high-revving performance engines.

Crafted from forged chromoly steel and finished with a diamond-like carbon coating, these cam followers are engineered to deliver exceptional strength, reduced friction, and outstanding wear resistance, ideal for demanding street or track use. Each unit is precision-ground for consistent clearances and smooth, stable valvetrain motion at all RPMs. Despite heavy-duty construction, our design retains the same weight as the factory rocker arm, preserving OE valvetrain geometry and balance while offering superior longevity and performance.

Rocker arms wear in conjunction with the camshafts, meaning the two must be replaced simultaneously. Aftermarket and performance camshaft options (Schrick, CAT-Cams, etc.) are typically ground from softer blanks and, as a result, cannot be used with factory rocker arms. We tested our performance cam followers with aftermarket camshafts to validate compatibility, ensuring smooth, reliable, and safe operation under demanding conditions.

Features:

Forged chromoly construction for maximum strength and durability Diamond-like carbon-coated surface reduces friction, extends service life, and permits compatibility with aftermarket and performance camshaft options Precision-ground tolerances ensure consistent and quiet operation OEM weight match maintains valvetrain balance and reliability Superior wear resistance for performance and endurance applications NOTE: Rocker arms are wear items and must be replaced alongside a new set of camshafts, regardless of profile or manufacturer. Installing a new set of rocker arms onto a used set of camshafts is NOT recommended.
