There has been a fair amount of conversations regarding Oil catch cans on direct injected motors on the FocusST site. Realizing that our little Fiesta ST has not been out that long i am wondering if it could also benefit from one. There are plenty of horrific pictures of valves caked with cruddy deposits that makes me feel it could not hurt. There are also pictures of what people catch when they do install catch cans. Has anyone added one to their car yet or have any thoughts on the subject. They seem like they are not that expensive and easy to install. Thoughts?
