Shops quote $3,500–$5,300 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.
Toyota built the 3UR-FE 5.7 V8 without conventional gaskets in several key places. The cam towers, the housings that hold the camshafts on top of each cylinder head, and the front timing cover are sealed with factory-applied RTV sealant (Toyota calls it FIPG). Sealant isn't a gasket: after fifteen-plus years of heat cycles, especially with Ontario's deep-freeze winters and hot summers, the RTV hardens, shrinks, and lets go. Oil starts weeping from the cam-tower-to-head joint, typically at the back of the engine first, where it runs down onto the bellhousing and exhaust.
The timing cover seam usually starts seeping in the same era, and the original water pump tends to start leaking from its weep hole around the 100,000 km mark. That's why this is a bundle, not three separate jobs: fixing the cam towers properly means pulling the camshafts and resealing the towers, and most of that teardown is shared with the timing cover and the water pump. Doing them one at a time means paying for the same disassembly twice or three times.
Done right, old sealant fully cleaned off, surfaces prepped, genuine Toyota FIPG applied in the correct bead pattern, everything torqued to spec, the reseal lasts as long as the factory job did, often longer. Done lazy (a smear of parts-store RTV over a dirty surface), it leaks again within a year. The prep is the job.

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 $3,500–$5,300 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $3,500–$5,300, 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 $3,500–$5,300 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 $3,500–$5,300 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.
These leaks only travel in one direction: wider. Oil dripping onto hot exhaust makes the smell you're noticing now, and chronic low oil is the real risk, a 5.7 run low on oil under load is a far bigger bill than any reseal. Oil migrating down the back of the engine also soaks the upper oil pan joint, which is how these trucks end up misdiagnosed with rear main seal leaks. And if the water pump is seeping, it doesn't heal; it eventually lets go and takes your coolant with it.
You can, but it's usually false economy on this engine. The teardown overlaps heavily, so doing them separately means paying for much of the same labour twice. If your cam towers are dry and only the pump is weeping, we'll tell you that honestly, we inspect first and only bundle what's actually leaking.
The factory seal lasted 15+ years and a couple hundred thousand kilometres, that's what a proper FIPG job gets you. Repeat failures happen when the old sealant isn't fully removed or the wrong product is used. We clean every surface back to bare metal, use genuine Toyota FIPG, and torque to spec, which is exactly the factory process.
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 $3,500–$5,300 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 $3,500–$5,300 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.
