Oiling System for BMW E46 M3 S54 (1999-2005)

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!)

VTT is happy to introduce the first and only available plug and play crankcase breather kits for ALL BMW applications that use the two-prong oil tab style oil fill caps. With this breather simply remove your oil cap, install the breather, and instantly free up horsepower, improve turbo draining, remove crankcase pressure, all while adding a cool look to your engine bay.

Can be used by itself with the stock PCV system to eliminate crankcase pressure, or with any number of PCV setups for the ultimate in crankcase pressure relieve 

Made from 6061-T6 Aircraft aluminum anodized black for a long-lasting finish, 4 stainless steel baffles for complete oil control, a PTFE one way check ball, a high-quality filter, and clamp all work together to keep crankcase pressure where it belongs, out of your crankcase.

This breather will fit:
 ALL BMW's with the two-prong style oil fill cap including but not limited to N54, N55, S55, S54

NOTE: NOT ALL THE MODELS LISTED HAVE THE SAME HOOD CLEARANCE, WE CANNOT SAY WHICH MODELS WILL HAVE CLEARANCE ISSUES, AND WHICH WILL NOT AS WE HAVE NOT TEST IT ON ALL MODELS. IF YOU ARE ORDERING THE BREATHER FOR ANYTHING OTHER THAN AN N54 TEST CLOSE YOUR HOOD CAREFULLY TO ENSURE CLEARANCE IF IT DOES NOT FIT LET US KNOW, AND WE WILL GET YOU A REFUND ONCE THE BREATHER IS RETURNED.

MODEL LIST OF REPORTED CLEARANCE ISSUES: N55 E/F 3 SERIES

Upgrade your BMW's oil pressure sensor setup with the Oil Distribution/Sending Block. This versatile block is designed to mount in the stock oil pressure sensor location on the oil filter housing or in the original location on the engine block. It allows the use of up to two aftermarket sending units (not included) along with the factory sensor, providing accurate pressure and temperature measurements. Engineered for reliability and cleanliness, it ensures a reliable setup for your BMW's oil pressure monitoring needs.

• Mounts in stock oil pressure sensor location for easy installation
• Allows use of up to two aftermarket sending units in addition to the factory sensor
• Incorporates factory sending unit for utilizing the factory oil pressure light
• Threaded for one M12x1.5 port and two 1/8th NPT ports for versatility
• Includes banjo bolt and crush washers for secure installation
• Compatible with various BMW engines including M20, M42, M50, M52, M54, N52, N54, S50, S52, S54, S65, M10, S14, and M30

Elevate your custom installation with the ECS -10AN O-Ring Boss fitting, a crucial component that connects your ECS Tuning Catch Can to a 3/4" ID hose. This fitting simplifies your plumbing setup, ensuring a seamless solution.

Featuring a pre-installed Viton O-ring, this fitting is engineered for excellence, providing a leak-proof seal that resists the effects of oil and fuel exposure, guaranteeing long-term durability.

The 3/4" nipple is thoughtfully designed with barbs to secure hose position effectively, minimizing the risk of hose disconnection. Keep in mind that clamps and hoses are available for separate purchase. These fittings are sold individually, with most installations requiring a pair of them.

Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned.  Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case.  Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits in the intake manifold, intake ports, and on the back of intake valves.  All will eventually lead to poor performance and reduced fuel economy, and the presence of this oil mist in the intake charge may even increase the risk of engine-damaging detonation. 

With forced induction, track use, and/or extended high RPM usage, these symptoms increase as the factory PCV system is overwhelmed, and a catch can becomes a must for your E46 M3. This kit is a direct fit making this an easy reversal if desired as well as maintaining a clean appearance by utilizing the open "smuggler's compartment" on the passenger side of the engine bay.

ECS engineers developed a catch can that utilizes a strategically designed 4 chamber baffle plate system engineered to create multiple changes in the direction of airflow to cause oil droplets to fall out of suspension, maximizing the efficiency of the PCV air/oil separation.  A dipstick is integrated into the cap so you can monitor the oil level, and the can is easily serviced.  At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil.  The ECS Oil Catch Can is CNC machined from billet 6061-T6 aluminum and with a stealthy black anodized finish for lasting durability and appearance, and includes everything needed for an OEM-like fully reversible installation.  

The ECS Oil Catch Can is made from aluminum and with a stealthy black anodized finish. The location is key as heat will evaporate the oil and send too much vapor back into the engine (where cooler air will turn it back into fluid). The ECS OCC also has a factory-like appearance. Having a kit designed specifically for your E46 M3 makes for a clean looking setup that any skill level mechanic can install. 

Note: Since the crankcase vent system is considered part of the overall emissions system, installing this may be a violation of local, state, and federal laws. While exemptions are made for track/race and off-road use, check with your local state inspection facility on using this in street-driven vehicles.

Modern emission regulations require a closed PCV/Breather system for cleaner operation. However, inefficient oil particle capture can lead to excessive oil vapor ingestion, causing carbon buildup, reduced performance, and fuel economy. ECS Tuning's updated ECS Baffled Oil Catch Can, now with an easy-to-empty 1/4" drain fitting, is engineered to collect toxic blow-by gases, minimize carbon deposits, and reduce oil contamination within engine oil. Recirculating oil vapor ensures emissions compliance without venting to the atmosphere.
