Re-use of the copper washer on the oil pan plug should not pose any problem. Just DON'T OVER TIGHTEN it - get it nice and snug but if you go at it like the Incredible Hulk then you'll strip it and you'll need a new oil pan.



There are many things I want to do to my CD - a new oil pan ain't one of 'em.

I wouldn't reuse the copper washer ad infinitum, but reusing it once shouldn't be a problem.

One thing I love about these cars is that I am able to reach under there to drain out the oil without even jacking up the car, which promotes frequent oil changes.
