Oil venting and circulation continues to be a problem on BMW engines and now even more so on the turbocharged N54 and N55 engines. The existing stock system does a very poor job of separating fluid and vapor and this leads to an oily film or even small pools of oil throughout the turbos and intake. We're seeing a lot more 135 and 335 cars with drivability and performance issues because oil has sneaked by the ring seals and is coating the intake piping, intercooler, intake valves, and other critical areas. The problem is worsened with higher boost levels. Oil is excellent for lubricating moving parts but terrible when it gets into the combustion chamber, effectively lowering the octane rating and reducing performance. Our own shop has gone the extra step and offers media blasting of the intake valves to strip away the oily buildup we have seen.
Our shop also strongly recommends an oil catch can be installed in the line for the crankcase vent. The oil catch can traps oil as it leaves the valve cover and holds it in a canister. Whatever minimal vapors are left over in the oil is then vented back through the canister and into the intake where it is safe to be burned up in the engine or recirculated back through the system again. This is the way the system was designed! At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil. A dipstick is integrated into the cap so you can monitor the oil level. Installing one of these will avoid costly repairs in the future and help maintain your boost and performance. It's one of the smartest modifications you can make because it demonstrates a well-thought out tuning strategy and care for the condition of your engine.
The ECS Oil Catch Can is made from aluminum and with a stealthy black anodized finish. Multiple brackets are available so you're not limited on where to mount it. 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.
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.

Pro-GUARD D2 Oil Filters are the next generation in oil filter technology. Pro-GUARD D2 Oil Filters deliver increased flow and efficiency that are demanded from performance gas applications. This cartridge style filter comes with a built-in seal for a hassle free installation.
The factory E9X oil filter housing cap is made of plastic which, by nature of the material, dissipates heat poorly and is prone to failure over repeated heat cycles. By contrast to the OEM unit, our cap is constructed from 6061-T6 aircraft-grade aluminum which promises two functional benefits: greater longevity and cooler running throughout its life cycle.
So too will the oil itself benefit: By getting your oil up to temperature quickly, but tangentially evacuating excess heat, the aluminum oil filter housing cap will help your fluid operate within its working range while effectively preventing thermal breakdown.
Each cap has been meticulously manufactured on a DMG Mori 5-Axis with specially sourced tooling to achieve some of the cap's intricate details. Anodized, the housing cap’s details are happily preserved but offer up a valuable way for an enthusiast to express their individuality. Four colors are available at launch to maximize choice: Ferrari Red, Royal Blue, Hard Coat Clear, and Hard Coat Black.
Appropriately, our latest livery box echoes a Gulf theme—echoing our motorsport intent and ties to the culture that has inspired us to create from the beginning.

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 and carbon buildup 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 oil mist can in the intake charge even increase the risk of engine damaging detonation.
With direct injected engines this problem becomes more prevalent, and the N54 in your 135i or 335i is no exception. We're seeing a lot of N54 powered cars with drivability and performance issues due to significant carbon buildup in the intake ports and backs of intake valves. The “factory fix” is a walnut blasting service that commonly needs performed every 30,000 to 70,000 miles. Don't be part of this statistic! Our shop recommends an oil catch can be installed in-line in the PCV system to help reduce the build-up of performance robbing deposits and greatly reduce the need for costly walnut blasting service and related repairs in the future.
The ECS Engineers were able to get more effective results compared to the competition by routing all blow by gasses through the high-load PCV circuit to ensure the catch can is functioning under all engine operating conditions. The catch can 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. Having a kit designed specifically for your E8X 135i or E9X 335i makes for a clean looking setup that any skill level mechanic can install.
