The purpose of this is to add 1/2 qt of additional oil capacity to the engine, raising the oil refill capacity (with new filter) from 3.9 qts. to 4.4 qts.
Tuesday I ordered the new oil gauge/dipstick from the Toyota dealer, picked it up today (Wed), $20.18 retail.
While it is the new part number, and IS marked differently, for a higher oil level than the original stick out of my '04, it DOES NOT have the "identification mark" depicted on page 2 of the bulletin.
It looks like you can attach only one attachment per post on this board (I'm used to boards that allow seven to ten per post), and since I don't have a hosting service such as Photobucket, and its better if they stay on this board (cannot get deleted when accounts go stale on the hosting service) I'll open several posts to show all the pics I have.
I have annotated the pics so it should be pretty self explanatory.
