So today me and a buddy got into a debate on the crush washer on our frs
And he said it mattered which way the crush washer faces when you put it on the drain plug and I said it doesn't matter .
He says that the flat side has to rest in the drain plug and the curved part goes to the pan
When I did the oil change it came with the curved part sitting on the drain plug and the flat one on the pan. So I put it back like that .
What do you guys think about this subject?
