Oil Catch Can?

[ifcho 0]

The 8v pumps quite a lot of oil through the breather on the cam cover (especially if having higher output pump), its not vapour, it is quite much oil that gets pumped there. There are early 8v engines without that breather (which should be returned to the low in the oil system (but not directly to the sump). Separate from that you have the breather system coming from the sump, which you should collect in the tank and empty somewhere else.
