There are 5 screws in the breather covers. From the driver's point of view; Left side has 3 screws, right side has 2 screws.
Here's my post on when I did mine: LINK - Breather covers and valve covers. There are a lot of detailed pictures with descriptions in the post. Hopefully it helps.
BTW, don't use a metal wire brush to remove the old RTV. The breather covers are magnesium alloy. Once you break the coating on them, any water will make them decay.
Gasoline works well to remove the old silicone.
