I am finishing up resealing my 1HD-T. When I was cleaning the dipstick tube (or Gauge Guide as Toyota calls it), both the o-ring and the double edge ring above it were dry and cracking. I removed both and can only find a part number for the bottom o-ring anywhere online. The double edge ring seems to only come already ON the tube? Which also seems to be NA. I find it hard to believe that the tube seal is not available on its own. Am I missing something? Does anyone have a workaround for this?
