Hi valeriecoronalopez73,
There are 2 places that can cause engine oil leakages into the plug holes.
1. Valve cover plug seals. You can replace by removing the valve cover.
2. Cam carrier O ring seal. You need to remove the cam carrier to replace. This would normally have more oil in cylinder #3 as there is a pressure passage within the O ring seals.
