Maintenance on the gf's Hyundai Elantra. I changed the oil and filter. All was well until I noticed a slow oil drip the next day. Got under it with flashlight. The leak is coming from the drain plug (bolt). Absolutely dry above the plug, and even above the pan. Dry under the new filter. But a nice fat drop hanging off the plug. It has a crush washer. I reused the existing crush washer. Hmmm. Maybe the crush washer has to be brand new each oil change? Most cars I change oil on don't even have crush washers, but if they do, I just reuse them, and they don't start leaking. Hmmm...
John: Yes, new crush washers are a good thing. Or, you can install one of these:
