Shops quote $4,000–$6,000 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 LX570 and Land Cruiser 200 run the same 3UR-FE 5.7 V8 as the Tundra, and they inherit its signature aging pattern: the factory FIPG sealant at the cam towers and timing cover hardens and releases after years of heat cycles. The first sign is usually oil collecting at the left rear of the engine, where the cam-tower joint weeps and gravity carries it down toward the bellhousing and exhaust, hence the burning smell after a drive. The original water pump typically starts seeping in the same era.
On these trucks there's frequently a fourth player: the valley plate, the oil-to-coolant heat exchanger sitting in the V of the engine under the intake. Its gaskets fail and coolant seeps into the valley, where it evaporates off the hot engine, which is why so many LX and Land Cruiser owners chase a coolant loss that never leaves a puddle. When the cam towers come apart, checking and resealing the valley plate at the same teardown is the obvious move.
These are six-figure-kilometre trucks built to run for decades, and the engines are mechanically excellent, it's purely the sealant that ages out. A proper bundle reseal with genuine Toyota FIPG, surfaces cleaned to bare metal, resets the clock for another fifteen-plus years. Piecemeal repairs on this engine are how owners end up paying for the same teardown three times.

Cam Tower, Timing Cover & Water Pump Reseal Bundle 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 $4,000–$6,000 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $4,000–$6,000, 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 $4,000–$6,000 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 $4,000–$6,000 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: Cam Tower, Timing Cover & Water Pump Reseal Bundle 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.
Left alone, the oil migrates down the back of the engine and starts soaking the upper oil pan joint, at which point shops start quoting rear main seals for a leak that isn't one. The invisible coolant loss is the sneakier risk: a valley plate seep can dehydrate the cooling system gradually, and the first hard symptom of low coolant on a 5.7 is the temperature gauge on a hot day with a load on. These trucks are worth fixing properly; that's exactly why deferring this gets expensive.
That's the valley plate signature. It sits in the V of the engine under the intake, and when its gaskets seep, the coolant lands on hot metal and evaporates before it ever reaches the ground. The evidence is the dropping reservoir and a faint sweet smell, not a puddle. We pressure-test and inspect the valley as part of this job.
Just leaking, in almost every case. The 3UR-FE is one of the most durable V8s Toyota has built, the internals routinely outlast the truck. What ages out is the factory sealant at its joints. Reseal it properly and the engine carries on like nothing happened.
No. Cam Tower, Timing Cover & Water Pump Reseal Bundle 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 $4,000–$6,000 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 $4,000–$6,000 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.
