I am building a car using a 2wd engine which will be mildly tuned. I don't really have room in the engine bay to run a separate breather tank like the ones you get in the kits available. I am looking at building a new breather box that looks very similar to the the original kidney box. It would sit in the same location, have a return to the sump and a small breather air filter on the top.

Are there any reason why this wouldn't work ?

Thanks in advance
