CAM SHAFT TOWER SEAL LEAKING ** PLEASE READ***

I’m gonna see what my options are this will be the second time I’ve been for work in the week and a half I have had it

 

Yeah unfortunately not the only problem I’ve had in my less than 2 weeks of owning it

 

What was the first time for?

 

First time I was hearing a clunking noise brought it in apparently some clip had broken off making my windshield cowl vibrate

 

Well I understand some issues will pop up with any truck but like you said with 580 miles on the truck it’s totally unacceptable but I don’t know what a new truck would help it will just end up leaking also

 

I hear you. I also bought a Toyota so I don't have to worry about crap like this, but that's about all I've been doing since learning about this issue. I've thought about trading it for something else, but what else would I get? I didn't buy a Chevy because of the AFM and vibration issues, and guys over on the Ford forums have tons of issues with their F150s. Don't even get me started on RAMs...

I've honestly considered getting a manual Tacoma, but I'm 6'4" and have two kids under 4 in car seats, so I'm not sure if the interior space will cut it...

 

ouch...

 

Yeah to say I’m pissed is a understatement coming from a Acura tlx that requires the transmission to be replaced at 15k miles I’m not happy one bit

 

I totally here ya man and have been totally pissed off since I noticed my leak. If I wanted a truck with issues at this low miles I would have bought a gm or ford. Mine started to show at @8000miles and the 1st dealer (location I bought it) said that wet seal is normal and the truck wasn’t leaking. Second dealer acknowledged the problem and said it’s a commmon issue in Tundras....appears a machining, surface cleaning issue at the factory before the sealant is applied... I am waiting until my 10k service and I think she will go under the knife.. I would expect this for the big 3 but not with Toyota. I will be contacting corporate to see if they will extend my warranty.. good luck and keep us posted..

 

Man I am sorry to hear that, I am pissed mine is leaking at 21k, 580miles is just unacceptable. With the issue carrying on into 2018 I think we wont see this issue resolved until the next gen Tundra.

I have thought about trading mine as well but options are scarce, Ford and Dodge are a no go for me. Double cab Silverado rear seat sucks for room and finding a crew cab 6ft bed Silvy with 3.42 rear is tough. I have thought about goin 2500hd 6.0 l96 is a pretty bulletproof engine.

 

I will definitely be having a talk with the gm of the dealership tomorrow and contacting Toyota after that

 

I'm starting to think its not a machining/sealant problem. This is what we are told and mostly what you come up with searching for answers to the problem. But if this is actually the problem why has Toyota allowed it to exist for so long? How hard is it to rectify the problem at the factory, makes no sense. I read one thread where a guy said that its a design flaw, to much movement within this location for an FIPG sealant. Who knows, seems like these days it doesn't matter what you buy anymore they all have issues, very frustrating as the consumer.

 

I contacted Toyota on Friday about extending my warranty, I should hear back tomorrow from my case manager. Good luck and keep us posted.

 

Anyone specific I should call or just the 1-800 number on their website and explain my situation

 

not only Tundras since 2008 ish but Sequoias also use the same engine...
It won't be fixed til next gen Tundra and a completely new engine imo.

 

Just call the 1-800 number, you explain your situation, they will check it against the dealerships info and then assign you a case manager.

That's what I'm thinking, plus the fact that the fix is to gob on an insane amount of FIPG seems more like a band aid then an actual fix.

Well the factory issue is what we hear from higher up. And being that engine is in the Sequoia, Landcruiser & Lexus it makes sense more over design, because I have not done nor seen a Landcruiser leak, and Sequoia & Lexus i have only done 1 each, and we have a heavy amount of Sequoias in my region. Not saying they don't but it is alot more on the rare side.

As far as the repair, the FIPG does great, and you do not want to gob it on, it will wont seal and will leak, you do a fine bead all the way around, and it won't leak again.

 

Well at least that’s re assuring after getting it fixed I won’t have the same problem again

 

Yup its on in how its applied, it needs to be dry and oil free, and time to set up. When I do them, if i get it re-sealed by noon, I may at least start it at the end of the day, but usually whenever i finish, I let them set the rest of the day & overnight.

Isn't the sequoia engine built at the same factory as the Tundra or are the made in Japan? The factory seal is a nice bead all the way around, I have seen lots of pictures online after the repair and it looks like a 5yr old applied the sealant. I think we need to be sending our trucks your way to be fixed as your knowledge and procedures on this are the best I have read about so far.

Well thank you, its not knowledge I/m proud of as it means I do a lot but i do learn all I can about them and fix them correctly. But even so, as a whole, its still a small % of them that leak. Even so with it leaking or not, I still wouldn't hesitate buying a Tundra, leaking or not.

Tundra is made in Texas, Sequoia is made in Indiana (if i recall) and Landcruiser is made in Japan. I know the 5.7 is assembled in another american plant for tundra & sequoia, I'm not sure if they are on the same assembly line or not though.

 

This issue for Toyota and the AFM/vibration for GM is why I am still driving my 05 Z71. Have not considered (and wont) Ford or Ram.

My BIL has a GMC 2500HD with the 6.0 gasser. Says it does not have AFM, pulls like a mule and gets 13 to 17 mpg. Sounds close to the Tundra so maybe I will go test drive it. Not comparing at all to the Tundra, just looking for alternatives.

Cannot believe it about the 2018 with under 1000 miles. Man I just hate that for you.

Found online - "However, while the Lexus engine is produced in Japan, the only plant in the world building the i-Force 5.7-liter is Toyota's plant in Huntsville, Alabama. And the aluminum engine block and heads are cast by Bodine Aluminum (owned by Toyota) in Troy, Missouri. So this is the engine with the most North American content Toyota has ever built. Japan, however, had plenty to do with the design."

 

honestly I seen my share of bad engines on japanese vehicles as well: Acura and Honda for example..

 

Well no dice with corporate extending my warranty, Which I figured was going to be the case. I don't know how people get them to do the things they post like warranty extensions because I can never get them to do anything. They said no warranty extension because I'm still under warranty, I explained to him the severity of the repair and pulling of the motor would not leave me with the confidence of a factory installed engine anymore. Rep said he understood and then offered me $350 towards service, which does me no good as I service my own truck. I Countered with them keeping the $350 and authorizing the dealership to reseal the driver side cam tower while the engine is out so I wouldn't have to go through this again. No dice, told me there has to be a failure for the repair to take place. Just don't get it, shoot they were saving money with my counter offer since the book time on the driverside is 2hrs once engine is out and $100hr labor rate. I guess I will just settle with there $350 offer, let the repair take place and run the truck to just before warranty expires and trade it off. No way I will go through having the motor pulled again once the driver side starts leaking.

6.0l96 2500hd is what I have been looking at, mirage is about the same as the Tundy. Only bummer is the Tundra has more get up and go, but that 6.0 is a pretty solid motor.

If the sequoia and Tundra engines are made in the same plant, why is this not seen in Sequoias? Maybe something else is at play here like engine bay heat or something, there has to be a different variable at play causing the Tundra failures.

 

This is true, it happens with all makes, everyone seems to go thru phases of it from what ive seen

 

Sorry to hear they won't let them do the other side. Yea i didn't see Toyota extending warranty as its still in powertrain. As far as like you were saying about people getting stuff covered outside of warranty, that depends on several things. The type of repair, common or rare, money, and the biggest is service history, Toyota likes paper trails,and being able to see what all has been done and recommended to be done. I know a lot like to get down and do their own maint, which saves money and some just like doing it but when push comes to shove vs Toyota, how can you prove everything has been done. We see a lot get declined when there is lack of history, the vehicle only come in for a couple free oil changes or a free rattle or recalls, and decline stuff, but then come in after warranty and want something large covered. I know it it sucks especially for the do-it-yourself people, like myself, i would be screwed, cuz I do everything to my truck personally, but I am able to have tickets wrote on them when i do maint.

 

New member here with a possible cam tower leak. My truck is a 2016 Tundra TRD PRO Crewmax with only 12,000 miles. Every once in a while I step out of the truck after a drive or warm up, and I catch a whiff of what smells like crankcase blowby or burning oil. I’ve inspected both sides of the bottom edge of the valve covers and nothing visible yet. Called the dealer today and the service writer says that in order to reseal the cam covers, there must be an active visible leak, and not a seep. Toyota will not cover a seep. Great, so I drive it more, develop an active leak, oil drips to the exhaust manifold and now my truck is going up in flames. If it was a Ford, no problem, let her burn; but not a TRD Pro.

 

Welcome! Sorry to hear that.

 

That really sucks, I'm sorry to hear that. It seems even more ridiculous that they won't fix the other side while they're in there. Hearing stories like this doesn't inspire any more confidence in Toyota...
