Thanks for the link. The more I read the more I want to do this mod. My X consumes oil and smells like burned oil on the driver's side of the engine. I suspect something has broken in the CCV. An oil smell this bad coming from the VC gasket would be showing up somewhere around the perimeter of the VC to head interface, and I just don't see it.

This car is my son's daily driver and he cannot be stranded at school during the winter with no transport - I already experienced this with a busted expansion tank that was about $600 to fix at the stealership. I'm thinking this is more of a preventive maintenance move than anything!

As far as I'm concerned - X5 community to the rescue!
