Shops quote $3,300–$4,400 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 2UZ-FE 4.7 V8 carries a large front timing cover that has to seal against three different surfaces at once: the block, and each cylinder head. The trouble spot is the step where the Bank 1 (driver's side) head meets the block, a junction where the gasket must bridge two surfaces that expand at slightly different rates with every heat cycle. After enough seasons of Ontario's freeze-and-bake cycle, the gasket gives up right at that step, and oil begins seeping down the front driver's side of the engine.
This isn't a rare fluke. Toyota acknowledged the pattern in a technical service bulletin. The leaked oil tracks down across the front of the block and finds the exhaust manifold, which is the burning smell owners notice at stoplights long before they ever see a drip on the ground. Because the smell precedes the puddle, the leak is often further along than it looks.
The repair is honest, labour-heavy work: the front of the engine comes apart, and on a timing-belt engine, that means the belt comes off too, the cover comes off, every surface is cleaned, and new gaskets and seal go on. That overlap is also the silver lining: if your timing belt or water pump is anywhere near due, this teardown and that one are largely the same teardown, and combining them saves you the better part of a second labour bill.
If your Toyota is doing any of these, this is the likely cause:

Front Timing Cover Gasket Reseal 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 $3,300–$4,400 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $3,300–$4,400, 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 $3,300–$4,400 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 $3,300–$4,400 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: Front Timing Cover Gasket Reseal 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.
Oil meeting the exhaust manifold is the part not to sit on, it's the smell today and a smoke-show or worse on a long climb tomorrow. Beyond that, it's a steady drain on your oil level between changes on an engine that owners famously never check because 'it's a Toyota.' The gasket failure only widens with heat cycles, and the oil tracking down the front of the engine eventually contaminates the timing belt area, rubber and oil being a famously short marriage.
Fair question, front-of-engine leaks on the 2UZ get misread. We degrease the area and trace the leak (dye if needed) before committing to the big teardown. The TSB-pattern leak shows at the Bank 1 head-block step specifically; if yours turns out to be a cheaper fix higher up, that's what you'll hear from us.
No. Front Timing Cover Gasket Reseal 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 $3,300–$4,400 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 $3,300–$4,400 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.
