Car was at Toyota dealer yesterday for oil change, they noted theres a lot of engine oil leaking and was soaked all over the engine- they couldnt see where it was coming from. I already knew there were leaks but not like this. Valve cover gaskets were replaced 2 weeks ago.
They power washed the engine did the oil change and put fluorescent dye in the oil and said come back in 500 miles to see where its leaking.
Car has 252K miles yes its gonna be leaking oil--Im thinking oil pan seal, front seal, rear seal, will see. Im worried about cost to repair but will have to suck it up pay it-- its still too expensive to get a new car right now with high prices and interest rates!!
From my experience the first oil leaks that occur on the 2IS350 usually are rear main, and valve covers. In your case, obviously not rear main. On my 224k mile 350 the valve covers are fine but rear main is just barely wet. At 250k miles id be surprised if it wasn't leaking oil.
Can I make a suggestion?
Start ONE thread of the cars history and add new issues as the issues grow. As in, update the main post with the current issue, and as it grows, add a link to post #1 with the new issue. It will help you and us. Honestly!
Will you get as many hits, i doubt it but its mostly the vetrans supporting you.
UPDATE: Toyota dealer re-examined oil leaks--mostly coming from metal oil feed tubes--not the tubes but the gaskets/washers. I got the washers will go to an independent shop for repair, dealer charges too much.
I would also take some time to pressure wash and brake cleaner wash all the oil off all over the place. That way you can always look and see when there is a problem and likely where its coming from.

UPDATE: When I got the oil change last week I did notice they overfilled the oil, it was a bit above the max level on the stick. Oil capacity is 6.6 qts I brought them 7 qts of Supertech 5W30 they put it all in.
That could be exacerbating the oil leaks out the seals.
I've seen those crush washer/banjo bolt leaks in the past mentioned on the forum here. I guess it's one of those things that can occur over time. Good thing is that it is probably the cheapest oil fix to be found. LOL! Maybe not the easiest to diagnosis or reach...but cheapest.
Sidenote worth mentioning...after my 2IS reached 150k miles, I began oil changes using high-mileage full syn Mobil 1 in hopes that my minor leaky VC, spark plug tubes, and front cover would be helped. Guess what...100% sealed by JUST the first oil change. The high-mileage oils (at least with Mobil 1 here) with their detergents to soften up the rubber seals are no joke! Something to keep in mind if you've not started using the high-mileage blend yet.

Mobil High mileage oil does wonders. My 15 IS350 was burning oil at high RPM and has reduced since using M1 High Mileage extended performance.

Funny thing I had recently decided to try the high milage oil. Since both my vehicles are 110K + miles now. Not that I ever noticed any burn off. Which I never really checked. Also I've switched to QuakerState awhile back. I've pretty much used all major brands. Just change your oil regularly, and call it a day. Next go will be the high milage QS version.

If you also switch from synthetic oil to conventional, it will also start leaking in the valve cover.

The burning oil is when the oil get dirty, it makes the oil ring sticky and get it stuck where it lose the purpose of it. I use Gumout multi tune up additive once I see that I have to add more oil and also to clean any gunk in the engine, also I use Motor flush when I change the oil. Follow the direction and never rev the engine. Don’t follow the 10k miles with those extended oil, it get’s too dirty. It’s better to stay 6k maximum with synthethic in oil change schedule.
UPDATE--yesterday had the front engine oil tubes crush washers replaced no more leaking! Now just need to power wash off the leftover oil stains/drips!
