Ok I must be stupid because I keep reading about the crush washer on the oil drain plug but I’m having issues. Mine has a washer on it near the bolt head but the inside diameter of the washer won’t allow it to slide past the fat part where the o ring is in order to remove it. I bought a new washer when I bought the oil filter and it will slide past the o ring but then I would have 2 washers on there and I’m afraid the o ring would then be too far “in”. Are there supposed to be 2 washers there? The parts diagram doesn’t show 2. What am I missing?
