    • As noted in the introduction there are two styles of oil caps. One of the cars used in the creation of this guide has the old style metal oil cap. Therefore, two fuel cap seals will be used; one for the fuel cap, and one for the oil cap. These are pictured.

    • The other car used has the new style plastic cap. In this case, you'll need one fuel cap seal, and one plastic oil cap seal.

    • Remove the first cap that is leaking. In this picture, it is the fuel cap.

    • Using a flat blade screwdriver, gently lift the old seal out. In the case of the old black fuel seal pictured, it was very brittle; it had become about as flexible as plastic instead of rubber.

    • Install the new seal, stretching it around the two metal tabs that extend out of the center of the cap.

    • Repeat with the next cap, in this case the metal oil cap. That seal was still fairly soft, and was not leaking on this car, but was replaced as preventative maintenance.

    • Alternatively, replace the seal on your new style plastic oil filler cap.

    • This seal is thinner, and a bit harder to remove. Gently pull it out with needle nose pliers being careful not to damage the cap.

    • Just like the seal on the fuel cap previously pictured, this seal is somewhat hardened and has a permanent groove in it. Replacing it with a new seal will likely stop the oil staining no the valve cover around it.

결론

Once the seals are replaced simply re-install the caps. After driving, check for any leaks and try to re-seat the seals if there are any.

I replaced my fuel filler cap sal with the blue nitrile? seal and it does seal. But!!! when t was time to refuel (approx 2 wks) the cap was extremely hard to break loose. Much too hard for my wife to open. So I applied some silicone grease. That helped but only one cycle worth. Seems diesel fuel dissolves the grease. So I'm back to replacing the $18 blue gasket with a regular gasket.
