New Year & 100k Birthday Presents: New Timing Cover, Radiator & Engine Drop!

I'd been wondering if spending the extra $$ on the 100,000 mile extended warranty was worth it or if I'd just thrown money away when I picked up my 2010 TE ~4.5 years ago. I knew that I'd roll over 100k on or before our Christmas road trip to AZ so when I took her in for an oil change before the trip I asked the tech to check over everything he could think of to make sure there weren't any issues that would be covered under warranty. She'd been driving fine but after reading the wheel bearing thread I was wondering if mine might be on their way out... Well, once the truck was on the lift I gave her my typical walk around to check the suspension, wheel bearings, etc (since the TRD wheel damage fiasco they've let me back in the service area to keep an eye on the wheels and do any of the lug removal/install work necessary). Once I made it to the passenger side front wheel to check the bearings, I noticed some oil spray residue in the wheel well -- it looked relatively fresh but there wasn't any oil on the tire so I knew they hadn't rolled it thru a fluid puddle on the trip from the drive in to the service bay. It had been a few weeks since I'd really looked at the passenger side closely (that side is against the wall in our garage so it's a bit out of sight, out of mind) but I definitely didn't have any oil on my garage floor to cause prior alarm. After pulling the skids we found a "tremendous buildup of gunk" on the bottom of the engine and surrouding hoses, etc and, after discussing with one of the senior techs they determined that the oil was coming from a leaky timing cover. It was a slow leak but it had obviously been going on for some time with the amount of gunk that had been building up. So, the service guy tells me that he'd guess ~20% of Toyota trucks have a timig cover problem at some point if the part isn't put on exactly right at the factory (apparently there's a small indentation that the gasket needs to fit into and if it's even a hair out of place it'll leak). Tells me the last time they had to replace a timing cover on a 4Runner it was a ~$1600 job, to which I replied "good thing I still have 148 miles left on my extended warranty!!!" Since the leak was very slight and she'd been holding oil just fine they said we'd be fine for the AZ road trip so we scheduled a date for the repair after we returned from the trip. Warranty repair was approved and as part of the work they'd have to do the coolant flush service that we were planning to do with the oil change -- so the upside is that I wasn't going to have to pay for the coolant flush service. Well, dropped her off yesterday and expected it would take a 1.5-2 days to get done...

Got a call this afternoon that they'd discovered that in order to get access to the timing cover they were going to have to pull the engine!!! The instructions apparently stated that engine removal wasn't required (I'm going to dig into the manual later and see if this is correct) and they'd been on the phone with Toyota to get direction on how to proceed. Toyota told them that since my VIN starts with a "JT" it was one of the early production runs and the engine will in fact need to be removed to gain access to the timing cover for the repair. Awesome. Happy New Year and 100k Birthday baby, your minor surgery just turned into a fairly major ordeal :( Oh, and in the process of removing the radiator one of the hose nipples broke off so I'm getting a new radiator as well...

Good news is that all of this is going to be covered under warranty and the tech doing the work has 34 years experience and is their most meticulous guy (according to one of the other service guys I know there). Bad news is that my engine looks like she got scapled and started puking parts onto the floor!!! I had no intention of getting rid of her anytime soon but after seeing half my engine parts setting to the side I'm more than a little concerned that I might be set up for other problems down the road even the best service guy doing the work...

Please, somebody tell me I'm crazy and she'll be fine, maybe even better than brand new when they get her put back together!

I'm thinking of having them go ahead and change the plugs while they're in there since they're due at 120k anyway. Any other recommendations for service items I should have them do while everything is in pieces???

Wow looks like a lot of work. .What dealer is doing it? I have a couple of friends that are mechanics at mark miller.

Don't all 4Runners Vin start with a JT?
 
I just had some bad news on my 2010 and I very unfortunately do not have an extended warranty (bought mine used) - just 'bout wanna puke I'm so sick to my stomach
 
What was the bad news on your 2010?
The above pix does indeed look like open heart surgery, but alas, it will go back together again. Heck, that's an afternoon of work for [MENTION=8206]harper7[/MENTION].
Good luck with the repair.
 
Two years ago my 2010 had the exact same problem. Took it in for the 30,000 mile service and was told the timing chain cover was leaking and it would be $1,300 to fix. After picking my brain up off the floor I realized I was still in the original warranty period (and the extended warranty period for that matter). Told them this and scheduled the service. The tech also had to pull the engine on mine and I'm thinking the same things you are. I can't believe my still new feeling vehicle that I've had for less than 1 year is having the engine removed. And just months before my planned trip to Moab. Pick it up a few days later and immediately drive out to a friends ranch for a weekend of hunting. While at the ranch notice it's leaking coolant. Drive the pickup to town and get a bottle of coolant. On Monday got Toyota to look at it again and make sure they put the radiator back right and tightened all the hoses and connections correctly and flush the factory coolant/Autozone coolant mix I created because I'm anal and only want authentic Toyota coolant in it. Since then 20,000 miles have passed without one problem and I never really think about it anymore. You should be fine.

With that much oil leaking, there had to be oil on your garage floor. I would be a little nervous with that much involved. How long is the dealers work warrantied for? I would be trading just before it was up.

Good to know and I hope you're right! Glad you're running smoothly since the ordeal.

It's at Toyota of Bountiful -- that's where I bought it from and I've developed a fairly good relationship with a few of the service/parts guys over the years. If I need a second opinion tho at some point tho I may take you up on an introduction to one if your friends.

I thought the same thing about the VIN and could have misunderstood what he was saying -- this was part of a conversation while we were walking back to the service area about the timing covers in Tundras and Tacomas being accessible w/o engine removal since they were designed differently and assembled in the US. According to the asst service manager the vehicles assembled in Japan are a different animal sometimes...
 
The timing chain cover in my 2010 was done a couple years ago. I wouldn't have known it without having read through the service records supplied by the previous owner. It drives just fine now 30k km later. Don't sweat it, and congratulate yourself on getting it done 148 miles before the warranty was up!

Yeah, I would have expected the same thing. There didn't seem to be too much splatter anywhere else in the wheel well so it's entirely possible that I ran thru something on the drive to the dealership and it was just a happy coincidence that prompted further inspection. There wasn't any snow/rain that day and the other wheel wells were clean tho. I've had a little oil on the garage floor twice with this truck but both times were the result of the quick oil change kiddos not replacing the drain plug crush washer like they're supposed to. The oil level stayed good on the road trip so I think what little oil has been leaking is sticking to the hot engine bits and/or skid plate.

If it wasn't for the fact that we need to get my wife a new vehicle soon I'd strongly consider trading it in now. We'll see how she drives once she's back together...

Ah yeah, I grew up in bountiful. The parts guy, brad is really cool. I bought so much stuff from them he ended up giving me a vendor discount.

My buddies at mark miller are Russ and Todd.

Also the owner of the "toy shop" in slc bought my 1997 supercharged 4Runner. He was pretty straight forward too, I think his name is Ralph.

It'll be fine. I'm an amateur and have been far further into engines than that, with zero problems afterward. My 07 Tacoma had the timing cover leak, it was fixed by a dealer at 60K miles. Last I heard, it was over 200K miles with no other issues.
 
Stopped by yesterday late afternoon to check on things, fully expecting that she wasn't going to be ready yet (eventhough the estimate was she'd be done by the end of the day...). Sure enough, all her guts were still on the floor and the engine was still having an "out of body" experience.

Here are some pics of the problem. Red arrows indicate where the leak was coming from. The engine is upside down so, as expected, the problem was on the upper part of the timing cover on the passenger side. There's a very slight indentation on the mating surface that is the culprit. Meant to take a pic from the side to show the oil residue stuck to the side of the block but got sidetracked talking to the tech. There wasn't a ton of oil, but just enough over time to have a ~6" dirty patch on the block where oil had seeped out and stuck to the engine from heat/dirt before mor dripped onto other bits beneath. There's enough dirt/dust in there that all the oil that was leaking had plenty of gunk to stick to instead of pooling on the skid plate and eventyally dripping onto the ground. Good news is everything else (transmission, etc) is in good shape with clean fluids, etc.

I know it would most likely depend on the dealer.... BUT say for instance I had the same problem. Instead I do 90% of my maintenance work and have receipts for Toyota oil, filters, etc.

Do you think a dealer would give me a hard time honoring the warranty because there is no service record?

No. Regular maintenance would have nothing to do with an improperly sealed timing cover.
 
Usually, the leak originates just a little to the left of your arrows, where the head, block, and timing cover meet.

I'm not understanding why they have to pull the engine for this...

IIRC, the oil pan has to be removed to remove the timing cover

Think that's the reason the engine has to come out. Think they thought they could get the oil pan off without removing the engine initially but couldn't get complete access to it so they called Toyota for guidance. I have a funny feeling the procedure actually calls for the engine to be removed in step 1 but haven't had a chance to confirm that yet...

Like [MENTION=78273]Jeremy556[/MENTION] said, regular maintenance doesnt touch any of the affected parts here. Moreover, it seems to be common enough (especially on Tacomas) that the warranty comany didn't ask any questions.

Now, if I was having CV or bearing problems then I bet I might have gotten some pushback since I installed the lift myself and an running 285s instead of stock tires (tho, enough of the service guys have lifted trucks that it would have worked out).
