    So what is a good way to fix this? I am losing oil from the drain plug.. IS it usually the plastic washer that needs to be replaced?

    When I changed the oil last, the bolt got snug, but not TIGHT. I was afraid to keep turning it b/c I thought it might strip. And I have a really bad habit of overtightening bolts..Then a couple days later I saw a small puddle on the floor and it turned out to be oil and its coming from the drain plug..

    If it isnt the washer, and it turns out to be the threads, can I use some thread sealant on it?I really dont want ot have to replace the pan, especially now that I am almost done and its almost road-worthy..

    I dont see why I couldnt use thread sealant b/c you use it in other places on the motor, but just wanted to double check. If I use it and it still leaks, then I know the threads are no good and the pan has to come off..

    Just replace the plastic washer and you should be good. It would be difficult to strip the threads on the oil drain plug. no need to put anything on the threads.

    I have never liked the hard plastic oil plug drain gaskets, the copper crush work good if the area around the plug is flat, but I usually use the soft fabric type (Honda's use them iirc), replace every 4 or 5 oil changes, no leaks.

    I just replaced my oil pan drain plug. It wasnt no really bad leak, just enough to notice it. No leak now, easy fixes are always good.

    I love it when fixes are easy. Couple of years ago a friend brings over an older Toyota Carolla. Says he thinks the motor is blown. Says it's missing real bad. He just put plugs, points, etc. I asked him when the was the last time the plug wires were changed. He said never. I said lets wait till it gets dark.

    He fires it up and it looks like the Fourth of July all over the place. Plug wires arcing all over. We head out to the Checker and get a new set. 20 minutes later the thing is purring. He says I'll be right back. 10 minutes later a case of Heiniken Bottles

    Your Chevrolet dealer's parts counter should still sell a replacement drain plug washer. This will be a steel ring with a rubber center. I replaced mine 5 or 6 years ago with no leaks to this date. Just snug it down enough with your wrench with just a little tug, not alot of force needed. :)
