    So it seems I have a very slow oil leak around the valve cover gasket...149k miles...2006 just for reference. I also noticed my power steeri g fluid pump seems to have a bit of a leak somewhere....and than the valve assembly that goes into the exhaust manifold seems to be leaking something around the hose....any ideas?20171106_162548.jpg 20171106_162548.jpg 20171106_162554.jpg 20171106_162548.jpg 20171106_162554.jpg 20171106_162554.jpg 20171106_162551.jpg

    Too few to list.
    My advice before anything is replaced is that you clean out the engine. I usually clean the engine once a year. With a clean engine, you can pin point where a leak is coming from instead of guessing what to replace.

    Well fortunately Valve Cover gaskets are pretty easy to see if they are leaking or not. The only thing I plan on doing before I replace mine is giving the engine a good scrubbing. I am going to mix some dawn dish soap with water in a spray bottle...Ill tape plastic around all the electric stuff...spray everything down with it, hose it off, then get to work.

    My 2006 2.7 is doing the same thing although not nearly as bad as yours. At this point it's just a few seeping areas, dark spots, on the valve cover.

    I am curious to see how much oil is pooled up inside the cylinder head in the spark plug recesses. It may just be leaking around the perimeter but could also be leaking from the inner areas that are harder to see without removing the intake.
