Unknown oil Leak from bottom of Engine
Hi,
I just started to observe some oil drops whenever i park my car after a drive of at least 15mins. I have problems finding out where the oil is leaking from and need your expertise.
I'm worried that i may to incur huge amounts of money to solve this problem after reading that some RX300 has gaskets issues after 50K miles. Worst of all is that there is no more warranty on the car.
Attached is a photo indicating the points that i noted drops of oil.
Pls advise.

Welcome to the Club.
There's two possibilities, the transmission or the engine. You'll have to confirm if it's engine oil (darker color, smells more burnt) or transmission oil (red color, somewhat sweet smell) by checking the drops that are coming out.
In the case of the transmission, that could be a transmission pump seal, like I had to deal with back here, https://www.clublexus.com/forums/sho...d.php?t=320390
or the usual culprit, the rear main seal, which we talked about a bit here, https://www.clublexus.com/forums/sho...d.php?t=389741

I suspect my prob will be the Rear main seal and the liquid that seeps out is darker in colour some what like over used cooking oil(no smell noted) but when it hits the heated pipings, it smells of burnt oil. It's now on a very slow drip and i realised it started to drip more after i did an oil change. I read in the thread that different grades of oil may prevent seepage?
But it does seem in both pictures that the oil would appear at roughly the same areas?
NExt question is do you know roughly how much it will cost me to get it replaced at the shops? As i don't have the tool and know how to ensure i don't make matters worst by DIY.

First start by cleaning ... make sure that you are not aggressive and make things worse.
The problem is that oil travels and as you drive the leak may be a foot or more away from where it drips.
With the grime gone, you can trace the leak.
Fix:
Some times it is better to live with a small issue instead of striving for a "full fix". The fix on an old engine can stress out a good part and potentially snowball.

Sounds like the rear main......My 2001 had the rear main seal leak after being stored in Arizona through the long /hot summer....
I am not sure if the heat/storage had anything to do with it.....
I had Power Toyota in Phoenix do it for about $800...
Good Luck

Hey there Jcjr,
I got pepboys to do an initial look to see where the leak is from and they guess it from the Rear main seal but ain't sure. Secondly, i'm hit with a potential leaky transmission as well! Sucks to be me...
Just got a quotation from LExus, the rear main seal will cost me 1.7K. But the good thing is that they will warranty it for a yr. So at least there's a peace of mind.
Where is power toyota's shop? Do they warranty the part after repairs?

P.S. If the trans. leak is the convertor seal that is easy to change when they have the trans. out for access to the rear main seal. The seal is cheap and the labor shouldn't be more than $20.-$30. I always suggest replacing the TC seal when you replace the rear main seal even if the TC seal isn't leaking. It's just so cheap to do it then.

Code58, How many hours of actual work did it take you?
Can you write a DIY?
Keep in mind, the labor charges are $100+/hr.

Hey Roox Jr....
I had mine done in the Toyota dealership in Tempe.....Ray Road auto complex....
I had it done in 2006.....and they were part of the "Power" dealers around the valley...
I know the economy has hurt the Power dealers .....
I would get a quote from the closest Toyota dealership to you....
They usually warrant the work for 1 year....the Toyota hourly rate is lower then Lexus.....The job is ALL labor...
I will use Toyota for my timing belt when the time comes...
Good Luck!!

Rear main leak on 2000 RX300 AWD
Any tip on how to R&R the rear engine main seal? I've done lots of work, restore, rebuilt engines on BMW but not familair with the AWD removal. I am familiar with FWD trans removal. Thanks.
