Pull the sensor connector off and check it for oil passthrough, it sometimes happens and can/will "wick" through the harness. I've only seen it happen personally on VW cars but the Porsche sensor is very similar/the same. I pull mine off each time I change to oil to make sure it's fine......

With yours actually having said you were out I would certainly at least check that if not also do a check of sensor resistance etc.

 

Have a 12 lawd with 272k miles and does not lose a drop over 5k miles. Seems like questions need to be answered. How much oil is used over how many miles? Is there a puddle of oil where car is stored? Can you see any leaks?
Some people here have vehicles that eat oil so depending on how much, may be normal.

 

This is just not true. There are many well documented cases of oil usage with this engine at high mileage that are unrelated to the valve spring recall.

 

I’m aware of those documented issues. But to say that it isn’t related to the valve spring recall goes against the clear warning that even Lexus gave to dealers about the oil consumption that could develop later in life if not done correctly. Proving it will be difficult but the warning is there nonetheless. The way to tell is if there is an internal oil leak from the FIPG seal between the camshaft housing and the cylinder head. Also those few documented cases of oil consumption are from the earlier years of the 460 (07-09) when the recall was more prevalent, not the later years of the 460.

 

Just because Lexus gave that warning for that particular repair does not mean all instances of oil use are linked to that repair. Multiple things can cause oil use. Correlation does not imply causation.

 

You gave specific advice and clearly claimed these engines don't burn oil under any other circumstance. You're wrong and dispensing bad advice. When you refuse to admit you were wrong with your advice, it hurts the forum and in particular new members who are looking for help. Suggest you think twice before defending incorrect advice if you want other members to respect your opinions.

 

Exactly…well said. We don’t need rose colored glasses here, it doesn’t help anybody. We need real and honest advice driven by experience. That’s what benefits people.

 

Okay....,and you can visually check that. Mine had the recall done and it's not leaking from there. It was burning it from the rings

 

did Lexus cover the repair?

 

Huh? I don't understand what they were supposed to cover, the recall was obviously covered by them.

 

I’m curious about your rings being covered as well

 

I've never even had the valve covers off on my 460 but I've had lots of other Toyota engines apart and can't see how this could be the the source of an internal oil leak. The cam housing/sub assy is under the valve covers bolted to the head, how would oil get into the cylinders...assuming the valve seals are good and the head isn't severely cracked?

 

Oh, I just fixed that issue myself.

 

But no, Lexus would not cover any repair for oil usage on a car that old, nor should they.
