Getting oil out of breather. 6BTA 330. Replaced turbo. Still getting oil. Ran another vent line. No oil. So it looks like the breather tube is plugged somewhere. Any ideas of how to clean the tube? Anything in the crankcase?

Here’s two links that are a MUST read with full understanding. And let’s see some pics of your setup including the full install and the current CCV system and your “temporary other vent line”
