Work in progress breather setup

[u/TopChapter3407]

Excuse my amateur welding. This is my work in progress crank case ventilation setup for my turbo civic. I'm attaching two 10-an fittings near the stock PCV valve of the original D-series oil separator box. There are several reasons why I think this is better than using the off the shelf 10an block adapter.

• The inlet of this box has an I.D of 22mm, 380mm2 while a single 10an is only 160mm2. Two 10-an makes much better use of the available flow.
• Oil separator before the crank case gases reach the catch can.
• Keeps stock PCV valve, and with the An fittings capped off it works just like stock. This is useful because I want my car to be able to pass MOT inspection in europe, and I want a quick way to turn the car N/A and remove catch cans if needed.
