    Default DIY: Valve Cover Gasket and Valve O-Rings

    This is for a 2002 Elantra GLS but the procedures should be similar for other model years.

    My valve cover gasket has started to leak and with 107k miles on the car I figured it didn't hurt to replace it and keep things looking the least filthy as possible.

    Tools required:

    10 mm deep socket
    14 mm deep socket
    Socket extension
    Mallet and block of wood
    Clean shop rags
    Clean place to work
    Flat bladed screw driver
    Pliers
    Sharpie
    Acetone

    Caution!
    **Before disconnecting battery, if you have an anti-theft radio make sure you have the code for it!
    **Make sure the engine is completely cool before this procedure.

    1. Disconnect Battery

    2. Remove accelerator cable from the back edge of the valve cover.



    3. Loosen the bolts and remove the spark plug cover.

    4. Using pliers loosen the hose clamps for the breather hose and PCV hose located on the back side of the valve cover and next to the right accelerator cable mount.





    5. Slide both hoses off the outlet stems and let hang.

    6. Remove the 4 bolts holding on the top timing belt cover and the cover too.





    7. Remove the 13 bolts for the valve cover.







    8. Using a sharpie, mark the spark plug wire assignment for each wire and pull out the wires and place them to the side of the engine.



    9. Pull off the valve cover. Make sure you've loosened and removed all bolts first. If the valve cover is stuck, take a mallet and a block of wood and hit the sides of the cover to get it loose. It's also a good idea to keep the exposed engine covered if the car is outside while you work on it.

    10. With the cover placed on the workbench, carefully remove any debris on the cover mating surface. Be absolutely sure not to scratch the metal surface and not get any debris into the engine. When the debris has been cleaned off, wipe the surface down with acetone so it's oil free. The reason is because any residue could cause an improper seal and oil leak. In the picture note the residue on the mating surface after I removed the cover. I cleaned it all the way around not just where the lines are. Also clean the mating surface of the cover itself once the gasket has been removed. I'm not sure if acetone on the plastic cover is safe since some plastics are reactive to acetone.





    11. There are several items to replace on the valve cover. The gasket runs along the outside and all the way around. There are also 4 seals. You can also see the PCV valve and breather outlet more clearly. The PCV valve will also be replaced.





    12. To remove the spark plug seals, take a flat bladed screw driver and mallet and place the valve cover on your work surface, on a cloth and tap out each one by placing the driver blade along the edge marked here. There is a metal band inside each seal so they cannot be pulled out.



    13. Pull out the cover gasket and replace with the new one.

    14. Remove the sponge from around the PCV valve.



    15. Using a 14mm deep socket, remove the PCV valve and replace with the new one. Put the sponge back over the new valve.
    **NOTE** My PCV valve has never been replaced with 107k miles on the car. It may not have needed it yet but it's a $5 part and since the cover was going to be off it was one of those things I thought is just common sense to do.





    16. Place the rebuilt valve cover over the engine and reassemble in the opposite order everything was removed. When tightening the valve cover bolts, start in the middle of the cover and loosen gradually in a cross-cross pattern outward. Tightening torque is between 72 - 84 inch-pounds or 6 - 7 ft.-lb.

    Should work now. I didn't realize the album was created and made "unlisted". I changed it to "public" so it should be all better.

    Nice write-up, but: you don't want people to laugh at you, so... 2 things:

    1- Those are the spark plug seals
    2- They are seals or gaskets, not o-rings

    I may update this later with pics in the thread but for now it's just the links since it's faster. The links all appear the same but they are not. The forum just truncates the URLs since they are too long.

    Seals noted. Thanks.

    ^ There is only 1 ONE link, to one picture. Granted, I can surf through the pics, and smart enough to figure it out. Others may not be so inclined.

    If this is to be a DIY, then it needs to be done right. At least put links under each numbered section, to each individual pic.

    I will have to figure out what is wrong. There are links under just about every number already.

    Mine went around the same time. Was thinking about making a DIY, but Autozone gave me the wrong gasket and I was pissed.

    I didn't really see any need for it but the Haynes manual called for it so I figured it wouldn't hurt anything.

    Links fixed. Not sure why Google's Picassa wasn't working properly. Also, having trouble getting the pics to load in directly to the thread so the links will unfortunately have to do for the time being. Anyone have any ideas why the forum is dropping the "[IMG]...[/IMG]" tags off and just giving a URL?

    Sorry it's been so long to fix this. I have had some other things that just took greater precedent this weekend.

    you do realize that the plug wires are labeled at the coil right? no need to mark up the vavle cover.

    all in all a good write up!!

    ^ My thoughts exactly, not to mention, ALL 4 spark plug wires are different lengths, and can ideally only go to 1 particular spark plug hole.

    Additionally, there is no reason to remove the wires from the coil packs, but if someone did do that, it's still easy to figure out.

    Thanks all for the compliments. No idea why Google's Picassa was such a problem. It really shouldn't be that hard to link to. I guess I could see all the links and pics because I'm the album owner so I wouldn't have never known.

    Regarding the markings, it all sits under the plastic cover so it's not visible unless the cover is removed. Also easy enough to remove if I had a need to. I guess it's just engraved in my head to always mark before removing from previous older vehicles.

    And while I'm sure someone noticed the temperature bar in my screenshot and wondered where I live, I have to say after looking at the engine pics of XDs in climates of snow and lots of rain, I'm glad I have no rust...just dust and dirt from LA suburbian desert. =)

    wow looks alot easier than the honda accord i had, there was oil in the plug tubes and not only did you have to replace those and the valve cover gasket but you also had to loosen off the bolts on the rocker assembly and lift it out to replace O rings underneath the rocker assembly. went smoothly though so i have high hopes for this. wasnt too fun to remove that plastic/aluminum engine cover to discover oil on the engine around the valve cover when changing the alternator
