So to protect our
MK7 Golf 1.8T project car, we have recently added one of own Clean Catch EK Oil Separators.
Why do I need a catch can?
With the direct injection motors, the valves have a tendency to develop carbon buildup on the back. This prevents the valves from closing all the way when they are supposed to be which leads to undesired running conditions, and hard starts. A catch can will help to prevent those deposits by collection oil vapor which then turns to liquid which can be easily emptied through various methods.
How many miles does it take to start seeing build up?
Well, glad you asked. We recently came across a post by
The Humble Mechanic who is a factory trained VW tech. He had a 1.8T TSI in his bay with only 11k miles This is how the valves looked:

IMPORTANT NOTE: Our Clean Catch retains the factory oil separator in all applications rather than replacing it, which means you have TWO levels of defense, rather than just relying solely on the can. Many people see ancillary machined pieces and mistake them for being better. This is not the case! Our kits are specifically designed to work in conjunction with what the original engineers developed, only our kit improves upon it.
Here's a look at the can installed in the MK7:
