Do catch cans "brands" matter should I fit one? GR/GU 2002 Y61 3.0 Di

Sounds interesting. Especially when I spent most of the afternoon cleaning the throttle body. It was absolutely awful, seems that's never been cleaned before. Full of carbon and soot. The reward was I now have a like new throttle body. Also cleaned what was obvious and could see on the intake. It was nearly blocked.

So I guess this is all somehow related to the fact there was no catch can fitted here. The one I'm talking about above costs 120 euros including vat. That's roughly AUD 200. It's got a drain pipe bit that normally goes back to the sump. But I'll just clip a good length of hose and put a tap in the end for easy drain.

You might want to spend another day or two removing the intake manifold and giving that a clean if your throttle body was bad. No catch can and a functioning EGR valve is the root of all evil in a diesel motor. Get a catch can that works, ie one with an actual filter, and block the EGR.
