hi all, this is the crap that was in my catch tank , i use the modified open loop breather system ..karl sent me a drawing when i bought my oil separater on what pipes should be blocked off and were it all goes with this system the cvh breathes so much better, all the oil you see in this pic..



is what normally ends up in the bottom of your metering head
but mine is now clean as a whistle
also all the breather pipes or bigger..
