y'all are killin' me here......
Like others here, I bet I've changed crush-washers on oil-pans maybe a dozen times in my lifetime... and that's invariably been because I LOST IT IN THE DRAINED OIL.
I've reused literally hundreds of them.
Now, a crush-washer-under-pressure, like on a banjo-bolt or other similar installation, yeah, I'm MUCH more finicky about those. Many years ago, I bought an assortment and stuck it on the shelf. I Literally have a lifetime supply of crush-washers on the shelf, but I still reuse the crush-washer on the oil-pan.... until it gets lost.
And can we stop being disgusted with each other?
There are so many things dividing our society these days, let's not let crush-washers be one of them. Let's save that disgust for politics and face-masks.
