My drain plug is leaking a bit and I found two different types of washers, one is plastic/rubber and the other is copper. Does anyone find one of those working better than the other?

Oil drain plug washer types

I like the ones that are copper with an inner rubber seal.

what he said.copper with rubber seal.it seems like i break the plasric/rubber ones too easily.most dont have a seperate seal.there is usually just rubber at the end of the bolt that squishes when you hit the pan.just tighten the plug into the hole till its tight.i really like those best.
Anyone got any part numbers for good washers? Noticed my teflon (or whatever it is) seal that was new with the motor isn't holding up to the oil changes.

Technically you should be changing the washer everytime you remove the plug (no one ever does though).
I kind of figured the same thing. Washer has obviously taken a "set", but this is the first one I've seen that actually leaks like this. Even took some fine sandpaper to the pan (making sure to keep it out of the pan of course) and made sure nothing was interfering with the seal.
Can you just ask at a parts place for this washer, or find it in the "help" section? And are they going to have a "good" one?

Any parts store carries the drain plug washer. They probably have several different types to choose from as well.
If I can find them, do you reuse the copper/rubber ones, or replace every time? Curious if I can expect any longevity out of them, or just chalk the expense up to routine maintenance?
I assume this is what you are talking about:

Link only takes you to the website. I personally reuse the gaskets until i discover a leak then i change it unless i see a problem with it once it's removed.
I still have a leaky problem too but it seem like I need to get a new pan to completely fix the problem so I just got a new rubber coated washer and gooped it with RTV and it solved the problem for now.

When I went to fix mine, I discovered the plug wasn't as tight as I thought. 
I got spare washers for next time though.

NAPA part # 704-1953 is a metal gasket, with a rubber center.
I went to the GM dealer and they sold me a metal washer with a rubber piece in the middle. It cost 3-4 bucks. I should have gotten a part number.
The plug currently has the original washer that came with the 78. It was plastic and has become very cracked. It actually does not leak. But I think it make just break apart at any time being that it is so brittle and cracked.

Another way to fix that problem is to install a valve in place of the drain plug. They used to sell a cool one that actually had a control cable attached.
You could just pull over a pan, pull a knob in the dash and drain your oil without ever getting under your truck.
I never had the guts to put one of those on. I always figured someone would pull the knob to see what it did.
But they still make the manual ones.

Here is another place that sells them. This outfit also sells a hose clamp that acts as a backup safety.

While the clip might make you feel better, it looks like too much aggravation to me.
And, here on another forum, are some pictures of an installation.

Just something to consider.

I would use caution with any thing that reduced the diamter of the hole for oil to exit.
