Shops quote $3,200–$5,000 for this one, and the quote usually isn't the ripoff, the job really is that big. Here's what's actually failing, what the correct repair involves, and the honest part: this is not a job I do in a driveway.
The 2GR-FE 3.5 V6 in the RX350 and ES350 has a large two-piece timing cover sealed to the block and heads with factory-applied FIPG sealant, no conventional gasket. It's a fine design until the sealant ages out. After a decade of cold starts at minus twenty and summer crawls on the DVP, the sealant loses adhesion along the cover's long seam, and oil starts weeping out the front of the engine, right behind the accessory drive belt. It usually starts as a damp film and progresses to drips and spots on the garage floor.
Here's what makes this repair expensive everywhere: in the RX and ES, the engine sits transverse with the timing cover facing the frame rail. There is no honest way to remove the cover, clean both sealing surfaces properly, and reseal it with the engine in the car. The factory procedure has the engine and subframe coming out, roughly twenty-two hours of book labour for what is, at its heart, a tube of sealant and a couple of inexpensive seals. It's almost a pure labour job, which is why quotes vary so wildly between shops.
Ignore it and the leak doesn't stay cosmetic. Oil sprays off the spinning belt and pulleys, coating the belt (which then squeals and degrades), the alternator below, and engine mounts that swell and soften in oil. Eventually the oil loss itself becomes the problem on an engine that many owners only check at oil-change time.

Timing Cover Reseal (Engine-Out) is on my published list of jobs I turn down. It needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. That list is public on my trust page. I'd rather lose the job than learn it on your engine, and you should be suspicious of anyone who says yes to this over the phone.
So here's what I can genuinely do for you, holding a $3,200–$5,000 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $3,200–$5,000, have someone independent confirm that's actually what's wrong. This is a diagnosis, not the repair, no hoist, no lift, nothing comes apart. I scan it, test it, look at it with you, and tell you straight whether their diagnosis holds up. If it does, I say so and you go pay them with confidence.
Book the second opinion →At $3,200–$5,000 on a car that might be worth not much more, plenty of people replace instead of repair, that's a completely reasonable call. If that's where you're heading, get the next car measured before you hand over money: 150 published points, at the seller's location, written report the same day.
Book a pre-purchase inspection →Tell me what you've been quoted and what the car is doing. $100–$250 flat, at your location, and you get a straight answer either way.

Not so you can do it yourself, so you can tell whether the shop quoting you understands the job:
That's the job. It's why this one belongs on a hoist instead of in a driveway, and it's why $3,200–$5,000 usually isn't a ripoff, it's a big repair honestly priced. What's worth checking is whether that's really what your car needs.
Get the diagnosis confirmed firstPlain version: Timing Cover Reseal (Engine-Out) needs equipment a driveway doesn't have, a hoist to get under it properly, a press or a machine shop for the parts that come out, and a controlled space for an engine or gearbox that's in pieces for days. I work out of driveways with hand tools. That's not false modesty, it's the published limit of what I take on, and it's listed on my trust page alongside the warranty.
What that means for you: this page is here to tell you what's failing and what it should cost, so you walk into a shop knowing the job instead of nodding at a number. And if you want that number checked before you pay it, that part I can do, $100–$250 flat, at your location.
A weeping timing cover never reverses. The oil it sheds lands on your drive belt and pulleys, belts soaked in oil stretch, slip and fail early, and soaks the engine mounts, which oil destroys. The slow loss adds up between oil changes, and a 2GR run low is a much bigger conversation than a reseal. The leak rate also tends to step up suddenly once a section of the seam fully releases, so 'a little seep' can become a steady drip without warning.
Yes, with the right equipment and a sane setup. The factory procedure drops the engine and subframe out as a unit, and that can be done on level ground with proper lifting and support gear, which we bring. The honest trade-off is time: it's two days, and your car stays put for both. We confirm your parking situation works before booking.
Shops sometimes smear sealant on the outside of the seam or attempt partial access, it doesn't hold, because the fix requires cleaning both mating surfaces to bare metal, which is impossible in the chassis. Paying twice for a shortcut costs more than doing the factory job once. We only do it the right way.
Anything that's expensive to reach later and cheap to do now: the water pump, the crank front seal (included), cam seals if they show any weep, and a good look at the engine mounts that may have been oil-soaked. We'll show you photos and only add what's genuinely worth doing at this teardown.
No. Timing Cover Reseal (Engine-Out) is on my published list of jobs I turn down, it needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. I'd rather lose the job than learn it on your engine.
Two things, and both are real. A second-opinion diagnostic at your car, $100–$250 flat, at your location, so somebody independent confirms that's actually what's wrong before you commit to a $3,200–$5,000 repair. And if you're weighing replacing the car instead of fixing it, a pre-purchase inspection on the replacement, $149–$399 flat, at the seller's location.
Because the useful part isn't the wrench. It's knowing what's actually failing, what the correct repair involves, and that shops quote $3,200–$5,000 for it, so you walk in knowing the job instead of nodding at a number. If you want that number checked before you pay it, that part I can do.
