|G.A.S. BMW M54 CCV System Replacement|
German Auto Solutions is in the process of developing 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 is oil sludge induced clogging.
A clogged CCV will cause excessive 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.
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-servicablity 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 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 the blow by gasses and keep the engine crankcase at the required constant vacuum level.
The lack of blow by gas evacuation promotes quicker engine oil contamination, and the lack of crankcase vacuum reduces piston oil ring sealing which causes the excessive oil consumption.
The German Auto Solutions CCV system will be priced similar to a complete OEM system, be relocated to an easy to access area of the engine, be easily serviceable to clean the oil separator unit, and have replacement parts readily availably. The pictures on the left shown our revision-3 CAD models. Changes have been made to allow easier fitment of the unit into the space required, reduction in the number of machining operations to control cost and increase quality, as well as changes to increase structural integrity and enhanced cosmetic appearance.

Now that things have settled down a little bit, we are again starting to focus some resources to this long awaited product. We will start machining some beta prototypes in the near future. Keep checking back for updates.
