This verification was done right after installation. I used a BMW gasket, not the one they supplied, but I wasn't smart enough to reuse the original BMW bolts. Most of the screws they supply have irregular threads and are poorly cleaned - I got them cheap. I ripped off part of a thread in my head before I figured it out. The big problem is that you can't tighten them properly. If you use their bolts, tighten them to specification a few times or reuse old bolts. Note their propellers use a different washing system but appear to work the same as BMWs.
