Did BMW ever get a chance to look at the car or just Indy shops?

I haven't...I figured BMW would tell me that they have to replace all the aftermarket parts first before working on the boost leak. They always have to start fixing obviously not stock parts.

I replaced all those parts, but then I went to a catch can system. I'm concerned that the catchcan system may have messed up the valve somehow. I removed the catch cans but have silicon hose running to the crank case. I'd like to just replace it all again so it's oem hoses and parts again.
