Is the valvetronic servo you are referring to the big silver soda cans on each side of the valve cover? So to uninstall, unwind it, but to install, mash it down and cinch it with the 4 bolts?

I also have a front oil leak just moist all over in front an below the driver valve cover, but have lots of tailpipe smoke at idle-related you think?
