Crank Shaft Damage

Well he's definitely at a turning point......I only had 2K in mine

The head gasket on mine was already known when I bought it
after tearing into it....ran in to bad snout.....and cracked time cover on the backside of the HB

so spending another 4K to get essentially a new truck was a no brainer


really depends if the rest of the truck is a money pit......mine was from the south.....so zero rust


IF I'd paid $12K ~ 20K like some here........I would of ship my pants

and I'd lean towards stuff with a warranty .......at least 24mos

 

Might be the way to go... they say call for avalibility and its local.

Howdy neighbor. I’ve been in contact with service advisor John Sohl and he’s been great. I think having the original shop pay for Toyota to fix it would be pulling teeth. Even John at toyota said I basically have to give them an opportunity to right their wrong.

The $1700 was for the original estimated job of just replacing harmonic balancer and pulley before they realized the damage to crank which for new crank and seals bearing etc they quoted almost $9000…

I talked to the original shop today and they want to take a look at the damage themselves and go from there. Which is fair because the photos Toyota provided aren’t the best for assessing full damage as you mentioned.

I already told them that I won’t accept the crank shaft sleeve as a solution and the owner agreed with me and apologized on behalf of his employee that suggested it.

I’ll keep you guys posted.

 

Ugh man it does seem easier at this point but aside from this crankshaft BS I feel like this engine has so much life left in her!

 

Thank you for the extensive write up. Really hoping it doesn’t have to go this far and that the original shop owns up to their mistake and just fixes the damn thing. But good to have all this info beforehand so that I’m prepared before proceeding.

 

If the original shop ends up doing the repairs, you tell them 100 times, save all the old parts...
Tell them that from the get go, keeps them honest vs a patch repair...
They do a bandaid repair & they tell you, "yes, we replaced the crank"
Is shop #1 going to Poway T to inspect it?
Come up with a plan before you toe it all over the place, assuming its torn down still....

Shop #1 should also be on the hook for the bill at Poway T....

I dont know any of the service writers at Poway, just Dan the service manager.
Ive inspected a few Tacomas up there while I was trying to find my 24 replacement & they had paint defects so never followed through with them.
Im actually out in lakeside / El Cajon area...

 

Consider carefully....5vz is little more pricey to work on......$1700 just to change out a pulley!!!

block could last 500K.....but its the heads....they will not

 

So what is the consensus on the cause of the failure?

 

From Toyota notes, damper was installed in-correctly, not all the way on...
The keyway was shaved down, the other shop could argue that they didnt do that...

But cuz they didnt mention it, document it, etc, makes them guilty.....

 

I'm trying to understand what caused the original damage. Using a bad key? Bolt not torqued and lock-tight? Somebody tried to beat it on? Probably never know I guess with so many hands on it at this point.

 

I’m going to have every single thing they plan to do in writing before they touch it. Definitely telling them I want the old parts, photos/proof of work, etc.

I think getting them to foot the bill for Toyotas inspection would be tough. They could rebuttal that I could have brought it to them to inspect for free. I decided on the second opinion from Toyota on my own accord.
Shop #1 paying for the tow is reasonable and that will be the first hurdle of many to come.

 

At least they are willing to look at it and listen.

 

I haven't read the whole thread so pardon me if someone's already said this... but 9K is outrageous. I'd bet the engine pulled and reinstalled is between $1500/$2500 at the local shop and $4000 at the dealer... and once out a new crank is two hours work with a coffee break for any competent technician. I'd be asking the original shop (if you still trust them to do the work) what they would charge to install a new crank. I've seen sleeves work well, but they are kind of a question when a new crank would be a solid fix.

 

I would go talk to the toyota tech, tell him your plan, he can put the other shop in their place when they say, maybe this, maybe that, were not responsible, etc...
Have them come over to toyota & inspect it there, with you & tech present.....
Makes things more un-comfortable for them & maybe less trying to screw you at the end, they can feed you a line of BS explaining why their not at fault, when you have a professional tech that has your back....

You tell them, you want to have them inspect it at toyota & have a solid game plan in-place before towing back & forth, etc....
You didn't f it up, they were just in it, you can mention small claims court, BAR, BBB, etc, if they start getting weasely.....
Clearly documented by toyota, that they did the damage which is obviously very nice of them & they could have easily just took the high road & not got involved...

 

I have installed many sleeves, all of them on axle snouts where a replacement spindle or axle housing is not avalible and they have held up. How is this differernt, I am not 100% sure. If it were me and my truck and I was doing the work, I would sleeve it IF and only IF the woodruff slot would hold the woodruff key and harmonic balancer tight. If it fails I am only out a little time and a few dollars.

 

Hard to see the key and keyway - they're at the top of the crank while the image is taken from the lower side of it. A video of it from multiple angles uploaded to YouTube and linked here would be a lot better .

 

Few things Tuna
1-I think your on right track from seasoned members advice here with your current plan

2-if i made this mistake on my own taco, I would sleeve without hesitation. These sleeves are used regularly for incredibly expensive heavy machinery without issue(if done/installed correctly).
However
Appears a shop created the problem
I agree with not putting band aid on

3- this $9k dealership is understandable in this day and age. They want to replace everything bc #1-correcting another shops F-up #2-all shops now don’t want anything to do with customer’s perception of keeping the cost down. This is because those same customers that say ‘let’s not RR all bearings/oil pump to save cost’…….those are the same Ahole customers that return to the dealership and demand a new engine bc the bearings/OP weren’t replaced.

 

Agreed, photos from above would be better. These were taken by Toyota. I’m unfortunately out of town while this is all happening so I can’t be there in person to see it or take photos

 

Update:

I went down to the shop to look at crank and discuss the plan with the mechanic. He wants to replace the woodruff key, crank pulley, and harmonic balancer.
There is obviously some damage to crankshaft but the mechanic is stating that it’s not enough to cause mechanical issue or warrant replacing the entire crankshaft.

My initial reaction is that the crankshaft is damaged and they damaged it so they should replace it. However, I don’t have confidence or want this shop to handle such a large job of replacing the crank.

He apologized and took ownership of the mistake. Further stated that if he thought crank needed to be replaced he would replace it. I told him I’d think on it.

Thoughts of just replacing key with new crank pulley and HB?

 

Worst that can happen is it just destroys another HB
.....sooo worth a shot?


problem is what if it gives away 3yrs from now

when you have others work on your truck this is the risk you always take

why anyone would run a repair shop is beyond me.......you'll get blamed for everything



If it was mine.....with what I know now........I would of found someone to weld that key in
got nothin to lose at that point......hopefully it was an aftermarket HB....instead of $400 oem

again I dont think they damaged it......or small chance anyways.....I think it was already there
from the grey residue....it almost looks someone tried to do the same, but with JB weld

but I'm just an old 5 lugger.....which many think are trash
