Show me your breather box

Hay, one of the reasons that I favor adding the valve cover fittings, AN-8 or larger, is because there are four push rod tubes per side of engine. I'm sure you are aware of the extra diameter in each push rod tube. These are direct portals, 8 in total for blow-by to exit.

I see your tubing at the original blow-by/oil filler housing location is larger than stock. You would have actually had to remove some of the original Volkswagen blow/by pieces in order for your application to be installed. This cannot be understood as if it were stock.

I think that we are all on the same page, (same understanding) whatever way that you address this. Understanding this problem and dealing with the blow-by, must be addressed if not oil leaks will occur.take care.
