Well thank you once again Steven. Perhaps if you weren't so pre occupied with trying to come up with another clever rant, which incidentally it wasn't, you might actually manage to extract the point of this discussion. The OP didn't have a washer at the time and a couple of us actually said in simple terms that this wasn't the end of the world. You can quite safely reuse a washer. I don't think that anyone said never use a new washer or that using a new washer was a daft idea. Simply that not using a new one every time wouldn't be detrimental. Now following your advice, I have been out and checked every one of the five cars on my drive and not one of them is dripping. Not from the sump nor any the diffs, nor transfer boxes. There is a slight leak on one of the locker actuators though. So good job you mentioned it.
Why aren't the plugs leaking? Well because I do the job well and it may surprise you that some of them had new washers! But it wasn't me in the original thread who was attempting an oil change. It was a self confessed newbie who had on his first occasion omitted to buy a new washer. We were simply reassuring him that the world would not end without using one this time.
I don't run a commercial garage servicing peoples' cars. But if I came to you, I'd expect all renewable parts to be changed (5% added to bill under consumables). Thing is this isn't a commercial forum. It's mates chatting. The question isn't whether it's right to change it; it's whether it's necessary. Necessary as in vital. And the answer to that is - no.
"Super moderator hero' I have to say I like that. Has a certain ring to it. Have absolutely no idea how that would be relevant as I wasn't expressing a view as a moderator. If I had been, I'd simply have deleted your posts in super hero style. Shazam!
But we don't do that here as we're nice people who don't generally resort to childish name calling and such.
Have a very nice evening. May all your sump washers be new ones.
