Hi
I have a 2001 XKR and I want to change the rocker cover breather hose (bank 2 USA driver side) now I think the part number is AJ8 4880 am I correct?

Looks like it goes from the rocker cover under the inter-cooler then clips onto the bottom of the throttle body elbow then into the heat shield and around under the coolant expansion tank where it connects to a steel pipe that goes down into the wheels arch and to the purge value.

I assume the best method to replace is to remove the throttle body and use a coat hanger wire pushed into the old one and tapped at the rocker cover end. Then withdraw the old one at the same time pushing the coat hanger wire. Re-install the reverse that should allow the pipe to follow the old path via the coat hanger wire.

Thanks
Simon
