Hi guys.
Today we made plugs ​​from 7075 aluminum to cancel balance shaft oil channels.
My mechanic ,how to detect oil channel, the video below explains how to cancel these channels.I will also add subtitles english version as soon as possible.
Balancing shaft oil will increase oil pressure by canceling channels.

And thanks mmephis for helping
