I've actually got one of those floating around, but not sure if the openings will be enough? Don't want to cause an internal pressure issue. Planning on getting walnut blasting done and putting one of these on beforehand. |

It looks like any other. I cut the original hose in the middle, spliced new hose to reach to and from the can, insulated the hose just like the original with foam pipe wrap. I just checked the can dipstick, I have some oil in it, not enough to be a worry, but I only drive on average 20 miles a week in winter.

Wasn't the catch can used to stop crank case vapor oil mixing with exhaust gases creating the carbon? Unless the n26 has an egr? |

The catch can is between the crankcase and PCV, to keep oil in both liquid and vapor form from reaching the intake manifold and intake valves, where it can cause carbon deposits. Detergent in the fuel can't clean those deposits with direct injection, as the fuel doesn't pass through the intake manifold or over the intake valves.

Catch can works only in boost mode
When not in boost (below some preset RPM), oil vapor and blow-by gasses are routed directly into intake trough passages integrated in the cylinder head cover. This is taken from N20 Technical manual, page 20 |
