Hard to tell for sure from the video, but it appears you have a significant
leak at the banjo for the oil supply line to
the rockershaft (0:12-0:15 on the second video clip). At high RPM that could
be significant. Otherwise the oil
movement doesn't appear excessive to me (at least at idle).
Sometimes, it's hard to get a good seal around the banjo. I believe the
washers should be copper, yours might be
aluminum. Also, the rockershaft pedestal that the supply line feeds can get
cross-threaded by the banjo bolt, causing
lack of seal.
