Replaced mine just before the holidays for the same reason, very common sadly however not a major problem to sort out. If you can fit a plenum spacer, you can replace the valve covers. Never done it before and taking my time took 2 hours to remove everything, an hour sadly to clean up all the old sealant as way too much had been used from a previous repair and another 2 hours to build back up. Having done it now, without the clean up job would say 3hrs start to finish.
Things to be mindful of, the rubber hose that links the 2 valve covers is known for splitting. Be sure to use a bit of gasket maker in the front corners as per the manufacturers pdf. Make sure of course the valve cover gasket stays in place during fitment.
Difficulty 2/5
