This is my first Direct Injection engine and ive heard the stories of intake valve carbon build up for years. Since I got a brand new engine I would like to try and avoid ever having to deal with that so im thinking of buying an oil catch can. However I have no experience with oil catch cans. They seem simple enough to install, how often do you need to empty them? Whats a good price to pay for one? Ive seen some as low as 20 dollars as others as high as 400 dollars. If anyone has installed one already, got any pictures or where or how you mounted it in the engine bay?
