G.A.S. BMW M54 CCV System Replacement Kit

 

German Auto Solutions has finished development of a long term replacement solution to the infamous BMW M54 CCV (Crankcase Controlled Ventilation) system. This system is notorious for a variety of failures, the most common of which are oil sludge induced clogging, cold weather freeze up and vacuum regulator failure.

A clogged CCV or a CCV with a failed vacuum regulator can result in increased oil consumption resulting in reduced spark plug, O2 sensor and catalytic convertor life. Excessive oil consumption can also result in reduce power and fuel economy due to retarded ignition timing caused by carbon deposit induced pre-ignition. Failure of the CCV vacuum regulator could result in oil being sucked up from the oil pan into the intake manifold resulting in increased oil consumption or even hydro-lock, a condition that can easily destroy an engine.

The stock CCV unit is located underneath the intake manifold and is very difficult to access for replacement. Replacing the CCV can be an entire day job and cost up to $320.00 depending on how much of the system you replace. The worst thing about replacing the stock CCV unit with another OEM unit, is that you will probably need to replace it again several more times during the life of your BMW. We have heard of BMW owners replacing their CCV as many as three times in three years.

The problem is a combination of the OEM design coupled with the location and non-serviceability of the CCV unit. As your BMW gets older it generates more blow by gasses which carry more oil through the CCV system. The oil that separates out of the blow by gasses in the CCV unit, tend to thicken into a thick gooey sludge (especially in cold weather) that clogs up the oil return path to, and through the dip stick tube and back to the oil pan. Once the system clogs, it's no longer able to remove oil from the blowby gases and keep the engine crankcase at the required constant vacuum level.

The German Auto Solutions CCV system will mount on top of the stock oil filter housing and will replace the factory oil filter cap. Once installed, the bottom section of the unit remains in place and acts as a mounting platform for the oil separator and vacuum regulator. All that is required is the removal of three 6mm Allen screws to change your oil filter and service the CCV unit. The oil separator comes off as a separate unit and will be easy to inspect and clean during a routine oil change.

Since the oil separator sits directly on top of the oil filter and is bathed in engine oil, the entire CCV unit runs at engine temperature which will eliminate any of the freezing failures of the factory BMW unit. The G.A.S. CCV also eliminates all the failure prone factory plastic hoses with an aluminum manifold and replaces the factory rubber oil drain back hose with a higher quality hose that should last the life of the vehicle. The kit will also come with a long flexible brush to clean the inside of the drain back back hose and a complete set of spare o-ring seals. Our latest revision now includes a unique "secondary" oil recovery section that allows it to recover more oil from the blowby gases then a brand new BMW CCV. Like all German Auto Solutions products this CCV replacement system will be of the highest quality and manufactured 100% here in the USA.

All components of the G.A.S. CCV assembly will be serviceable and have replacement parts readily available. The pictures on the left show our revision-8 CAD models. This product has been almost three years in development, including wet and dry flow bench testing along with extensive in vehicle testing.

The German Auto Solutions CCV System has now been in the field in customer vehicles for 6-12 months. So far all reported feedback has been very positive. 100% of customers gave the kit a rating of 8-10 in every category. All customers said that they would purchase the kit again, all said that they were experiencing equal or lower oil consumption compared to before the kit was installed, and all said that the install was fairly easy and straight forward. The second production run of G.A.S. CCV Kits will begin in September 2018.
