I am changing my oil today (2010 IS350 - 24k miles) I will take a look and see if there is any oil residue.

110k No oil leak. As i remember, my cousin (whose work for Lexus of Westminster) told me that i should check for oil leak when i take my car in for Valve spring recall.

I did have a rear-seal problem at one point where oil was leaking a bit after the Cold-Startup knocking recall was performed, but the dealer fixed it and been good ever since. The leak was very minor and really didn't have any performance issues other than the horrible smell when the oil was burning on the manifold.

Yes, Today my 2007 350 ES was diagnosed with and oil leak coming from the timing chain cover.
I have seen 2 separate mechanics and it is currently at a Lexus dealer for a repair to the tune of $3000. This car has only 56,000 miles on it. I really think Lexus should be responsible for this repair. fargosrpb

Why ? Your 7 or almost 8 year old car with very low mileage, have gaskets that do deteriorates over time. All manufacturers will have leaks over time.

Lexus master technician here.

I've seen a handful of IS 250 and 350 engines leaking oil from the timing cover. It's not nearly as common as the ES350 is, but it still happens occasionally. This seems to be an issue for the 2006 and 2007 IS vehicles, and not so much on the later years.

Glad to see that my '06 IS350 not had such oil leaks; those timing cover seals are expensive (labor) to fix.

I have RX 350 2007 with 87 K miles with recently diagnosed timing cover leak.
Lexus washes their hands off and I am stuck with a $3600 repair for timing cover oil leak.
Toyota dealer quoted 2600. Better than Lexus but still hell of a bill for an oil leak.
Poor craftmen's ship on Lexus side. I expect some leak on higher mileage vehicle but not $3600 to fix it.
I was also hoping they would cover some part of this repair as there was a TSB issued for this defect the same year as the mfg. year of my RX

07 IS350 51K, no leaks so far.

No offense to anyone who has had an oil leak just want to clarify one little thing. Anytime you have two pieces of metal or material with a seal in between them there will be a chance of a leak. We have a complex system of oil and cooling system on board of every modern vehicle. It does suck that it happens but it's just a part of life. Be glad you own a reliable vehicle and the engine or transmission is not known to grenade at a moments notice like vehicles of the past.

As for the astronomical price to fix this issue.... Buy OEM parts and take it to an independent shop or get a long block and do the work yourself.

For all mechanical related engine parts pay extra for OEM. The build quality of these parts are typically far superior than aftermarket parts. For typical consumables like windshield wiper blades go aftermarket as they can be just as good or in some cases better.
