So you think that an OCC doesn't do anything?

I will agree that the Oil Catch Can will not eliminate the carbon buildup, or need to clean.  In our area (I'm in Clarence), in the cold season, my OCC catches a bunch of water, and some oil/foamy crap.  I decided to collect and measure it.  With the cold December we had, I get between 6-8 oz of fluid every week.  I filled this 59 oz Orange Juice bottle since October 19 of this year.  The dark stuff on top smells like oil, but is low viscosity (like 3 in 1 oil, a little heavier than WD-40).  The necking of the bottle makes it look more dramatic than it really is, but at least 3/4 of the fluid is water.

Here is some info about my car:  08 MCSa, 83k miles, 15k per year, 20 miles driven each way to work, daily driver.  Passenger PCV port is blocked, BSH OCC.

If nothing else, I don't mind not running this water through the engine.

Have fun,

Mike

I also see a lot of water in mine during winter and it gets very annoying to empty it every week and I don't even drive much. Contemplating to remove it as well and just do carbon buildup cleaning when time comes. Mine made it to 62k before it needed it. I removed my passenger pcv block already. My car never felt right with it, especially when I pushed the car during autocross.

I wanted to buy this product at some point, but it looks like he doesn't sell it anymore. Seems like an easy method, but there a lot of posts saying sea foam won't work either.

Seafoam is just a stop gap measure. In the end, you end up needing the walnut shell cleaning.  I did the seafoam routine for years and was amazed at how bad the valves were when I did blast the valves.  Big difference in how the car runs after you do blast it - lots more air flow.
