VVT Oil Line - 2GR-FE Bank2 -what about Bank1 ?

[wtruck]

I want to replace the oil pipe (line) on bank1 of my 2007 RX350 because it also has a rubber hose that is prone to failure. (see attached 15771M)

I've been trying to identify the correct part (part#), Toyota/Lexus have a replacement part that is all steel and no rubber elbow. 

When I look at Lexus Parts sites I find (3) different part numbers

1. 15771-31010
2. 15707-31011
3. 15707-31012

Toyota list part number....

1. 15772-31030

I've attempted to order the Toyota part number online from a couple of different site, but, they won't allow me to order the part.  They require a VIN # and then say the part number doesn't match the VIN #.

I.E. https://parts.lexus.com/p/Lexus__/Engine-Oil-Cooler-Line/62915783/1577231030.html

 

So today I drove to a Lexus dealership.  They told me the correct part number that I need is....

1. 15707-31030

...and, this part cost  $96.68

The Toyota part is $33.50  (15772-31030)

Does anyone know if there is a difference between these 2 parts?  Other than the dollar amount of $63.18 ?????

I have to wonder why the part numbers are different.

2007 RX350 (FWD) - Lexus dealership told me the correct part number that I need is.... 15707-31030.....their part is $97 and Toyota part is $33.50 (15772-31030) The difference between these 2 parts?    $63.18

Found this post with still images and torque specs that was very helpful....

Fairly involved repair....

1. remove upper motor mount
2. drain hydraulic power steering reservoir & remove return line
3. remove cover for the bank1 VVTI oil line
4. passenger wheel off and remove inner wheel well cover (need to remove driver wheel too)
5. remove serpentine belt (and good time to replace)
6. remove power steering pump the most cumbersome

• 2 bolts
• high pressure line (probably want to replace this crush washer/s also Part no 44327-30030)
• disconnect sway bar links (both sides left/right)

When you're looking at the power steering pump you have to swivel and push (force) the pump UP and to the your LEFT.   The 2 bolts have to be removed completely, the top bolt passes thru a dog-ear clip that the pump has to lift up and out, then you can remove the high pressure line.

I found this video helpful for understanding steering pump removal, this gentleman had broken the dog-ear off the block of his motor.....

I have the same issue with my 2007 ES350.  What part numbers did you use? 

One thing I noticed is the Toyota part number fits the 2008 ES350....weird that the 2007 is different.
