Has anyone heard anything about a new design system for the CCV that German Auto Solutions is trying to develop? I came across this last night, but there is no date on the announcement on their website, so I don't know if this is something that has been on their back burner for awhile:

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.

I just dropped my e53 off at the indy shop (Autohaus Merkle) to get a new cold weather CCV kit and valve cover gasket installed, but I would have definitely rather have had an improved design. Not sure how much difference a little insulation on the cold weather package will make. I considered doing this job myself and the VCG wouldn't have been too tough, but it looked like the CCV would have taken me forever and a lot of frustration, and I can't afford to have the car down too long.
