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 🙂

E60 S85 M5 VANOS solenoid bleeding and replacement 

After replacing the rod bearings on the V10, you have to bleed the VANOS solenoids. In my case, this resulted in the solenoids failing the test, so they had to be replaced.

The video covers bleeding the solenoids with ISTA and highlights how to replace them. It’s actually a pretty straightforward job. I was trying to get away with not draining the coolant system. I almost succeeded until a couple of little pesky Torx screws on the right side of the engine became a pain, and I didn’t want to strip them.

The M5 is getting closer to being complete… until something else fails! 😀

E60 Rear Upper Control Arm Replacement DIY

If you have been following for a while, you will know that this is the last piece of the puzzle when it comes to getting the suspension on this fantastic V10 M5 sorted. The upper rear arms had failing ball joints and needed to be replaced. In the channel update video last week I went through the difference between the 06 arms and later models (you always need to check yours). 

As it turned out, the repair was not as straight forward as expected! The car has spent some time in the “salt belt”, causing some of the threads to be badly corroded. After trying several methods, I finally settled on using a big pair of vice grips to complete the job.
