How do you clean 240D oil/seperator

I am wondering if there is a way to take the vapor/oil seperator apart and clean it out...I got some blowby and the trap/seperaotr must be clogged because the drain pipe going into it weaps...Does anyone have any pics of one of these apart???

Thanks in advance!

I also saw this post in another thread, and it got me really curious? IF the seperator is plugged up the engine has to breath/vent pressure...could be pushing oil passed?

If there are vacuum problems and excessive blowby, then the vacuum lines and booster are the first places to look, especially if the engine starts and runs fine. For a quick test, disconnect the union on the pump hard line before the barbed fitting and plug it on the pump end. If your blowby decreases greatly, the issue is not an internal one.
