So I pull off the lower engine cover from my '07 GS350 a couple of days ago, ready to start my 60k service with the oil change. As soon as I get the cover off however, I see oil collecting on the oil pan, sway bar, and basically everything in a line up to the left side of the water pump.

No leakage visible from above at all, and oil level was still between the "full" marks on the dipstick. So I took it in to my dealership yesterday morning, and heard back from the SA that the gasket on the front engine cover is leaking. Replacement is $3,000 but is covered by my (3 month old, 48 mo./100k mile) extended warranty.![Woohoo](https://www.clublexus.com/forums/images/smilies/woohoo.gif)
The front engine cover (also called cam shaft/timing chain/belt front engine cover or timing chain/belt cover sub-assembly) is part number 11302 in the diagram below (Sewell Lexus rocks).

I know sometimes things just happen, but I'm surprised that I haven't seen this problem on any of the threads here. Has anyone else ever had this problem? Also wondering if anyone knows whether its possible that this happened during VVT actuator gear replacement (about 3 months/2k miles ago)?

That's what came to the top of my mind, given the timing and the fact that this seems to be a rare problem. Do you know for a fact whther or not they remove this cover to do that service?

The vvti cam recall has nothing to do with the front cover. There is a timing chain tensioner cover that has a gasket that could leak oil #11328 in your above pic that is replaced during the recall. It's possible the tech that did your recall loosened the lower vvti bolt and did not replace the gasket. Either way glad it's under warranty.

I picked up the car today, and had a chance to talk to one of their master techs about the problem.
He said that he has seen a lot of 2GR-FSE engines come in with failing FIPG (form in place gasket) seals, due to too much or too little sealant used at the factory. This was allegedly the problem with my car. Doesn't matter much to me since it was completely covered under extended warranty (didn't even have to pay the $50 deductible), but it's probably something everyone should keep an eye out for.
Like many others here, I had my water pump replaced due to leakage. Does anyone know if that used a factory FIPG seal as well?
If anyone else has experienced oil leaks through an FIPG seal on their 2GR-FSE engine, please share your experience.

It's a lot of labor...that's why it's so high...the last thing you want to do is to mess it up and have to start all over...
Find a Toyota/Lexus specialty shop if you don't want to pay Lexus prices...

Hi LexusLive!! LOL! How are you?
We all know that the quality of Lexus is crap and on the downslope. I wonder how many have this problem or is it a certain year that is plagues....maybe the 09 and could be why the ratings were low? Maybe...but this is the first case ive heard of.
For a second I thought I was on the Infiniti forum...lol

That is a quote. Proof that the 3.5 V6 is not infallible, and in fact appears to have oil containment issues not found with the 3GR-FSE. Stuff like this keeps bubbling up to the top of the forum, and I refuse to ignore it and to be made a fool for buying the GS 300.

If your leak is the same as mine, the engine cover reseal won't address the problem ... if it still leaks, have them check the gasket(s) that were removed during the VVTi service.
