Too much oil
I've researched online about methods to extract some oil after a recent overfill. So removed the dipstick and inserted a 1/4 inch vinyl tube into the opening. No problem and it reached what felt like the bottom, but nothing would siphon out, just air. Multiple attempts to make the vinyl tube go further, with no success. When removing the vinyl tube and measuring the length that it travelled down the dipstick tube into the pan, it measures exactly to the high level mark against the dipstick. So two things. One, I do not appear to have an overfill, even though the dipstick sometimes shows oil above the high level mark. Two, there must be a block somewhere in the system that prevents the vinyl tube from going all the way down into the oil pan. Oil cannot be extracted from the pan this way, at least not below the high level mark of the dipstick. Does this make sense?

When you remove the tube, is there oil on the bottom end? Like when you plug the top of a straw from a glass of liquid with your thumb plugging the top.
How far above the upper line is the oil level? You can be up to a quart overfilled with no problems. If you think you are way over, drain some out.

How far over the full line is it after the car sits overnight and you check it in the morning? 5/8" over the full line means you have 0.4 quarts too much oil. This is common. The official crankcase capacity is 6.4 quarts but in a regular ten minute oil change, about 0.4 quarts is left in the top of the engine and takes several hours to drain out. Probably 90% of these engines in Toyota and Lexus vehicles are running over the full mark. The dipstick will register exactly on full if the engine is started after an oil change ....... but if you take the car home and check the oil the next morning, it will be well over the full line.

The 1/4 inch tube you are using may be too wide and catches on something, probably the little dent from the o-ring. Other than the oil level high on dip stick, why do you think it's overfilled? Did you put in 7 qts? A shop uses a pump that measure how much oil they put into an engine, so they are not likely to overfill. I may have some 1/4 hose lying about, I can see if it goes into the oil pan tomorrow.

I just decided to remove enough oil to indicate the level is between the low and high marks, when this experiment started. At this point, I don't think I have too much oil. I think it's right on the money or slightly over.
Let me know what you think about it if you get to try it.
Thanks again.

Have you considered taking it to a shop? I know that you want to save money, but blowing your engine would cost even more.
Alternatively, you can clean your oil pan, drain the oil into the pan, then use 1qt containers to fill it back again.
