My Yaris is a 2010 Hatchback. I've done my own oil changes. Back in April (2024) I noticed the crush washers I had just purchased from the local Toyota dealership were these " blue felt looking aluminum" type. Did an oil change yesterday on both my Yaris and 07 FJ. Both blue type crush washers had to be removed with a putty knife; they were stuck on the oil pan. Before April 2024 I recall the crush washers were a dark color, possibly black?. Also, I noticed both drain bolts had lost torque/ tauntness......never occurred when using the "darker ones" of the past. Anyone know if the darker ones can be bought thru dealership?, if so, part number please. TIA
