07 Es 350 Timing Chain Cover Oil Leak

Recommended Posts

I have a 07 ES with about 46k miles. I noticed a small amount of oil on the garage floor. I monitored the leak over several weeks. It would amount to about a teaspoon or two over several days. Looked under the car, was not the oil filter or oil pan drain bolt. Leak appeared to be just behind the oil pan.

Took it to the Lexus dealer. They called the next day and said they needed a extra day or two. That made me a little nervous. They actually kept it for about four business days.

The leak was at the backside of the gasket for the timing chain cover. Apparently, during assembly, the guy that was supposed to seal the timing chain cover was not having a good day. When I got the car home, I started to read the service ticket. The parts required included: oil pan plug, sealant, oil filter, 7 qts oil, gasket, coolant, O-ring, another gasket, brake fluid and transmission fluid. Upon inquiry, I learned that they had to remove the engine and transmission out of the car to make the repair. They dropped it down to remove the engine. Fortunately, my Lexus dealer service department has an excellent reputation. The TSB covering the repair is EG010-07. Had the engine been out of warranty, the repair would have cost about $2200.

I'm sure glad I didn't ignor a very small oil leak.

I also had the oil hose failure a couple of years ago. They fixed that as well.

I had my ES 350 spring a very sudden bad leak, lost 2 quarts of oil over a 3 mile trip home. Oil and filter change confirm no problems with the filter, pan, or pan bolt. The leak appears to be coming from the front of the timing cover housing, only happens when the vehicle is running..I assume this means a catastrophic failure of the oil hose (dealer recall item) rather than a timing cover gasket. Am I right here? My car has 56K on it so I assume I am likely SOL, even though it is a specified recall item.

Can anyone comment further on similar experiences? Will Lexus pay for the tow if it is a hose? What about the whole repair?

Only a phone call to the nearest Lexus dealer will get you the answers you seek. However, given that 1) the engine falls under the extended drivetrain warranty, and 2) there's a TSB on this type of failure, you may be in luck! Let us know how this adventure turns out.

Interesting to see this subject timing cover leak etc. My 07 CPO ES350 is now at dealer for same problem. Thank goodness they honor the warranty. They advised me Friday they'd have to remove the engine to fix it. Imagine the labor on that one. Anyway, gave me a loaner till possibly this Wed.

Sure hope it goes back to together with no "new" problems created.

Mine is in the shop now and being told this is the issue-- I'm just over 70k and had the extended warranty -- they are trying to get an exception -- fingers crossed as from info here and research online it won't be cheap if I have to front this cost myself. From anyone that has had to pay out of pocket for this repair, what did it run you???

I took my ES 350 (122.5K mi) to the dealer yesterday. They quoted me $2,525 to do this repair.

My 2007 ES 350 has a timing chain cover sealant leak. With 60,000, it is out of warranty. Obviously, this is a factory defect on this model. Lexus will only give me $500 toward an almost $3,000 repair. OUCH!

My 07 es350, ~75k miles, was just quoted $5k for the repair by a Lexus dealership in redwood city, ca. Had the repair increased that much in a year?

I had the same problem last year at 66k. I had bought the vehicle in 2010 as a lease return with the extended 3 year warranty. Of course, it was about a year over the warranty, but well under the 100k mileage. After extended conversations with Lexus in Torrence, Ca. they agreed to pay for the labor which came to about $2,500 and I paid the parts of about $500. Of course they found other things wrong, mainly cv boot on one side which cost me another $450.

Since this repair is of a known defect in the silicon sealant of the timing chain cover at the time of manufacture, I would go to the mat with Torrance for them to pick up the labor, especially since you are under the 100k mileage part of the warranty. Then, you should be able to handle the parts, whatever that cost is. My $3,000 was at an agreed upon price between Torrance and the dealer, so there may have been some cost sharing there, as opposed to being straight "retail!"

Good lick!

Thanks for the help! The dealership says the warranty for this issue is 6yrs or 60k miles, both of which I exceed. They did however revise their price to $3900 and it includes a rear engine seal. They also said they would replace the valve cover gasket and only charge me for the parts. The next time I talk to them I'll see if they can make a case for me with Lexus corporate to pay for a portion of the repair like your case. Thanks again.

Good for you!. Just be sure that if the dealer does not support you (as mine did not!), you still should go to Torrance and make your case and don't take no for an answer.

I just heard from my dealership that I need this repair done on my 2008 ES350 (135K miles).  Quoted cost was around $3,000 and I'm unsure of the right decision.  Other than this issue and the fact that it will need new shocks badly  it seems to be in good working order and my plan was to keep it for at least a few more years.  I'm hesitant to put $3,000 into an 8 year old vehicle but at the same time, if it would give me a few more years, it might be worth it.  Has anyone had this done and if so, how did the car run afterwards?

The timing chain cover oil leak was the result of a manufacturing defect in the adhesive that attached it to the engine. This is well documented. If I were you, I would fight like hell with Lexus (not the dealer) to reimburse you for the repair. Most of the repair is labor and there is some room in the rates. Also, they found a problem with one of the CV boots and had to replace it, costing me about $450.  I did this thinking I would hold onto the car for a few more years. The car ran fine after the repair. But, later when the other CV boot had to be replaced at a cost of $650, I decided that this car was not worth the additional investment and traded it in.

What is the color of the leak? My 2007 ES350 has red liquid leak in the front, passenger side. What this liquid is?
