Wasn't sure which forum this question best belongs in, so trying here in Engines.
I currently have a breather can which collects the gas venting from my valve covers. It's right next to the gearbox at the back of the car and I'd like to add a vent line from my gearbox as well. The gearbox currently has a breather cap but mist sprays all over the gearbox, so I want to run a line to a can.
The question is, should I use a separate breather can for the trans, or would it be OK to weld on another bung onto the existing can? It's simpler, cheaper, and a weight savings to boot. The only potential downside I could think of is engine gases somehow making their way into the trans case, but I don't know if there'd ever be enough pressure from the engine gasses to force air back through the trans line, especially considering there is a big mesh breather on top!
