have 07 mercury grand marquis , removed intake for replacement , noticed oil in spark plug holes and decided needs valve cover gasket replacement , drivers side was an easy removal with intake removed , passenger side however is a different story .Removed wiring harness and placed in valley , have removed all bolts on passenger valve cover but left bottom access being blocked by evap , Considering removal of passenger and drivers side motor mounts and raising motor to gain access to last bolt ,is this the best avenue ? Do not want to remove evap or any of that stuff
