Your right about taking care of the sponsors. Thanks for posting this, I know this is in my future on my wife R57 and my R58
Same for me. She'll need this done eventually and I may just get done to be ahead of any issue. I think I'll take off the front end too like he did.
On my R56 I went ahead and replaced mine before it started to fail. The DT complete kit is great because it has new gaskets for the oil heat exchanger as well as everything needed for the oil feed lines.
