Oil Drain Plug Gasket installation

    Is there a way to install this WRONGLY? The one side is flat with a
    groove in the middle and the other side is semi-circular. Which side
    goes into the oil pan hole and which side fits against the drain plug
    head?

  2. The groove in the middle should go "out" as you place it on the drain plug -
    it will eventually be the side that goes against the oil pan. That is one
    of those "crush-able" o-rings, and that groove is what provides the seal.

    Key is to ALWAYS make sure you replace these crushable o-rings with every
    oil change. After they have been deformed that first time, if you try to
    re-use it, it will leak.

    Hope this helps.

  3. Better yet, replace the plug with a Fram or Fumoto drain valve and
    eliminate the need to replace the crush washers. They also eliminate the
    need to handle oily drain plugs.

    I've wondered how these work. Haven't really ever heard anyone who actually
    used one over a period of time make a comment about them. How long have you
    had yours in Brian? How many oil changes has it gone through?

    You should tell that to the original "crushable" o-ring under my 01
    Santa Fe.

    13 oil changes later, no leaks at the drain plug. I wish I could say
    that for the valve cover (leaking at gasket) that the idiot "Hyundai
    Certified" mechanic removed...

    IMHO, if you're destroying those rings on every usage (at least the
    brass/copper ones like the factory used) you really need to lay off the
    drain plug torque - its not a lugnut.

  6. You have me laughing at that, because often I have accused "fast oil change"
    mechanics of using the occasion to tighten the drain plug to do their
    chin-up exercises - it is unbelievable how tight that drain plug is when
    anybody other than me does the oil change.

    Usually I only use two or three fingers on the wrench.

    But still, if I forget to change that O-ring (which I have done twice), they
    have leaked.

    But the dealer gives me a whole bag-full for nothing, so it is no big deal
    for me to change them.

    Thanx for the info.

    My Hyundai 1996 Accent has over 213,000 miles on it. I just changed the oil
    in it today, and on my wife's 1993 Impreza with over 230,000 albeit rusting
    miles on it. Both cars use/take the same generic NAPA shrink wrapped
    filter. Both cars still have the original so-called crushable washer. Now,
    let's see which car makes it to over 300,000 miles first?

  8. I installed a Fram valve at the first oil change, so after the change
    last weekend I guess I've done a total of five with it in place over the
    2+ years I've had the car. Zero problems.

  9. I never changed the washer on my '94 Excel, either. If it was
    "crushable", it never crushed. ;-)

    Is the drain plug different on the V-6 vs. the I-4?

    I re-used the washer on my 4 cylinder Sonata as I didn't have one for
    the first oil change. No leak at all. I bought a bag with the case of
    filters I ordered online, but I don't see any problem re-using them a
    few times. The washer on my Chevy truck is the OEM washer and has been
    through 18 changes now.
