    I'm posting this for those who may have the same problem and want to fix it.

    My ride in 97 Explorer 4.0 ohv. . was burning some oil, slowly more and more, about a quart every 3000 miles or so. I only noticed a puff of blue on start up sometimes and figured (was hoping) the valve stem seals were going bad. (Also was getting more and more pinging under load).
    Two months ago I decided I'd change them out, Now two months later, about a 1000 miles and a couple cans of gumout, the dip stick still reads full and the pinging is almost totally gone.
    Also the engine runs so much better.Took me two days to do the job.

    I'm posting some picks of the engine and tools if any one considers doing this job.
    Tools needed, compressor and the plug hole adapter not pictured, spring compressor,and I bought a cheap (valve stem seal puller and installer) but not really needed, pliers and a socket will work.

    (Notice how worn the old seal to the left is) ^^^^
    (And the seals on the right)

    Also.
    You need a compressor and these attachments...Also start it at top dead center, I put my truck in 2nd gear with the e brake on, 5th would have been even better.Use a strong pen magnet or even some twizzers and make sure when you take off the valve spring retainer or (keeper's) there's some back pressure there, so that the valve does not fall into the cylinder. If you've never done this before watch a few youtube videos and read up on it .

    Thanks for posting with pictures!!!

    This works on many engines. I have done this on a half a dozen FE engines and a couple of 385 engines. Once put back together, like you said, the engine is good and will improve over time as well since the old oil is being burned. Running an engine cylinder cleaner helps as well.

    Since this is a mostly labor repair with valve cover gaskets, a do it your selfer spends almost nothing and makes a significant improvement on engine oil consumption and over all engine performance.

    True truck runs so much better now.With vehicles that are 20+ years old you have to know and learn how to work on them.The cost bringing them to a garage is greater than what the vehicles worth.

    Delayed maintenance is the down fall of many engines. Even with poor oil and a poor filter that is changed frequently most engines have a far better survival rate.
