Oily residue on the left rear spark plug area-Written by rudyg1937 on 10/12/2010 at 01:19 amIf it starts above the plug hole it is probably a cam seal leaking. A common,
not critical, problem.
Another possibility is it is not oil but is antifreeze from a leaking o-ring on
the water pipes in the heads.
