E60 S85 M5 PCV Valve Replacement 

During one of the previous videos, when the M5 was being aligned, we discovered a leak around the rear main seal area. However, this isn’t always caused by the rear main seal, so we had to trace the source. The video demonstrates where the leak was originating from and provides instructions on how to replace the PCV valves.

This video illustrates where the leak was coming from and how to replace the PCV valves. 

One day, hopefully, I will be able to drive the M5 without having to work on it 🙂
