Hi all I have a auq leon and imbin the process of getting a custom made oil catch tank. im getting an alluminium adapter made up to replace the main oil breather outlet from the engine, But I have to decide what width I want the pipe to be that goes to the oil catch tank since the outlet and inlet on the oil catch tank can be made to my specification. And I have noticed on some posts and threads that people go up to 19mm but there is no reason why they do this. I would like all the pipes to be the right size. Any ideas. I have the option of a 15mm and silicone or braided hose to match for the oil catch tank. Its all getting made buy a rally preperation specialist here in donegal.
