Replaceing an Aveo Valve Cover Gasket – December 2010

With around 75,000 miles, I started getting some excessive oil around the valve cover base. I had a full blown oil leak where the valve cover protects the spark plug galleys from getting any oil in them. This made for a couple of oily plugs which does not work out to well for performance. The install went pretty straight forward, while I was in there, I also removed the Exhaust Manifold and did some minor gasket match porting on the head and exhaust manifold.

The minor port work I did had some surprising results. There is a “test turn” which I would normally take around 65 as that’s all the car could really muster. After the porting, I am through third, into fourth and find myself lifting as 75 is a little too fast for this turn.

    Thank you for the slide show. I rather enjoyed the tunes. I thought this job was about this straight forward, but I still lack all tools and a certain amount of skill in tightening the valve cover down evenly. If I can find a local shade tree mechanic to install the valve cover – what is fair in time or cost by job?

    Hi,

    Thank you for the reply. I’m not sure what the book time is on this, but figure about an hour or two job.

    This might sound stupid but how did you port out the exhaust manifold? I enjoyed the slideshow.  It gives me a better idea of what to do before I start.

       I have an electric die grinder which combined with some porting bits allowed me to clean up the exhaust manifold ports a little bit. For the head, I shoved some paper towels in there and used a drill with different grinding stones followed by various grits of sand paper.

    Thank you for this! Helped me a lot since I had to do this too at 90k. Bad gaskets at factory?

      Glad I was able to help you out. As for lasting 90k, that’s pretty good. it’s a valve cover gasket, they aren’t exactly known for lasting a long time, even on “better made” cars like Toyotas and such.
