I just bought a 2005 Toyota Tundra w/ the V6 engine and 140k miles. I noticed seepage at my valve cover gaskets, and some oil on my ignition coils when I went to change the plugs. So I took everything apart to change the valve cover gaskets, spark plug tube seals, upper intake manifold gasket, etc. I discovered my lower intake had a build up of sludge and oil around the upper intake gasket. Is this abnormal buildup? Is it a sign of bigger issues like worn piston rings? While I still have everything apart I’d like to address the issue.
