If you are retrofitting a new DISA you can skip this step and keep the new O-ring in stock for a future failure.

What! More possible failures!!! I thought this was to cure all that. LOL Seriously, I hadn't realized this was for the only for the 530 style of Disa valve. Is the 525 version so different? Aren't they both M54 engines only varied by perhaps stroke or bore size? Cost anyway?

Forgot, great instructions but with the product you created and the detail involved why would anyone be surprise.
