Look at the photos above. See the gray cap with the "H"? That's the high pressure fitting for the A/C system. The oil tube is just to the right of that. There will be a black plastic cover over the engine with a V6 emblem, but if you look down at the corner on the passenger side you can see it.

Thank you, June Bug. I'm off to check out the '07. Thanks again.

Does anyone have a comparison pic showing the "old" defective design vs the "new" vvti oil line (still with the rubber section) that was used under the Limited Service Campaign (LSC)?

I've heard the rubber hose used is different (I'm wondering if there are visible markings on the hose), and I've also heard that the clamps that hold the hose onto the metal pipe portions were redesigned. I just would like to see with my own eyes.

Also, has anyone experienced their limited service campaign replacement vvti oil line fail?

I have an 07 that has the limited service campaign revised part, still with rubber section. Just debating if I should go the all metal route...

You would seem to be in a good position to post a picture or two of the revised pipe with the rubber section. When you do that, people will be able to contrast the pictures with the ones that have already been posted.

This was reported by Vee6er:

And KMonster posted this picture. The new rubber line has a yellow stripe:

Thanks to those that replied.

I haven't had time to check mine, but here is what I found:

Oil pressure hose failed - Page 4 - Club Lexus Forums

See post #51 at the link above. Good pic of the defective oil line. Visually the rubber looks fatigued (bulgy) and the clamp is cutting into the rubber.

That poster notes that the defective rubber is denoted by "AT OIL ACM" markings, while the LSC replacement is denoted by markings on the rubber showing "KK20 OIL ACM FKM".

I'll have to see what mine says...

Owner liked your Idea Junebug and wrote letter. Thanks

The owner needs to write a proper LETTER, and send it USPS mail with return receipt requested to the dealership's OWNER and/or GENERAL MANAGER. Also send a copy to TOYOTA also with return receipt. This will be noticed, fall into the right hands and be passed around to others. Keep the letter short and sweet, to the point, no more than 1 page if you can, and a brief mention of the possible involvement of an attorney won't hurt. We have the notice in writing that the repair should be covered up to March 2013 and lawyers just LOVE it when you have it in writing.

I sure am glad mine came with the metal oil line!
The letter you suggested can now be found on

as footnote [C] but without her name or address and with the last four VIN digits X'd out.

That's a nicely written letter! Hopefully it will get the attention of the right person.

I can deal with my current ECM flash issues rather than this crap any day.

I was interested to know the technical explanation behind the VVTi oil line failure. Here is an excerpt from Toyota Canada's response:

"Toyota has determined that on affected vehicles, the rubber portion of the engine oil supply hose for the VVT-I actuator on the cylinder head may develop a small crack due to the use of improper rubber material. These cracks can develop inside the oil hose from exposure to small amounts of corrosive components in positive crankcase ventilation (PCV) gases. If the vehicle is continuously operated in this condition, the crack in the hose may expand as a result of the oil pressure and engine oil may leak from the oil hose which can eventually cause damage to the vehicles engine."

I don't see why the new and properly designed hose (using the proper rubber) would give any problems. I agree, the metal hose is probably a fool proof solution, but having said that, there are many rubber hoses used in all makes and models of vehicles on the road today without issue. In this particular instance, some Toyota engineer/supplier/ or whomever spec'd the wrong type of rubber for the job....leading to a costly mistake.
