Alright folks,
I've been patiently waiting for time to pass and my car to accumulate miles after I installed the BSH OCC last summer. So far I've had the OCC installed for almost 10 months and over 10,000 miles. This includes one winter season here in Chicago.
This is the first time I removed/uninstalled it to check on the condition and the amount of the collected oil.
So without further due:
This is ALL the oil that the BSH OCC managed to collect over the entire period described above:
As you can see from the picture, the oil that was collected was barely enough to cover the bottom of this small plastic cup. I'd say this is about 2-3 fl. oz of oil collected.
Here is a video showing that the BSH OCC does a really poor job at collecting oil fumes. I apologize for the sound quality. I took this video with my cell phone.
The verdict: This OCC does a really poor job at collecting oil fumes. It is poorly engineered because it sits right above the hot turbo manifolds. Any condensed oil vapors will simply get heated up and evaporate back into the intake. Also, the condensating element inside is nothing more than a perforated aluminum rectangle suspended only halfway inside the cylinder.
