surely this is connected up all wrong?? does the return to the sump not need to be at the bottom and the breather connections at the middle /top ??

Doesnt the standard kidney breather not vent outwards and not inwards. Ie the pipe running from the bottom of the tank to the kidney is gonna cause a blockage, no?

The one i have label sump, is plumbed into the hole which is usually block off under the exhaust manifold near the rear.

The seperator tank doesnt look like a decent one to start with. Any ideas...

Heres i picture of the tank.
