Will Tacoma's suffer the same engine failure fate as the Tundra?

This article made me chuckle “the price of a trd pro tacoma goes up to nearly $50000”

 

I don’t take JD or CR as creditable sources of consumer info anymore. I mean JD seems to rotate through manufacturers, like motor trend for who’s best. CR on the other hand is usually blind to Toyota’s issues and seem to favor them over the competition all the time. The recent CR take on the tundra is surprising, but they usually trash everything else so we’ll see if maybe they are changing their stripes.

I tend to agree with some here who have said that Toyota is blaming machining debris because the alternatives make them look way worse.

 

Was it cam or was it crank ? Since it seems to be a bottom end issue I thought.

 

CR has been trash since they rigged the Samurai and Trooper rollover/evasion tests.

 

They are not credible in my book, I'm not even sure what they are and what value they offer to the consumer?

They aren't historically Toyota cheerleaders by any means. They have been giving the new Tundra a low grade since it's release, and with the Tundra's issues this has given CR and JD some validation in this regard.

 

Thought it was an oil starvation issue and a cam design with the main bearing. Let me see if I can find the video talking about it.

 

You’re saying everything right minus the cam/crank part IIRC. Main bearings are not on cams.

 

Yep I know, separate areas, pieces. He talked about it (main bearing issue) and he said the cam design too, trying to find the video for you, hes a toyota tech.

 

I always thought of CR as being big Toyota cheerleaders. At least in the past, when I read CR. But it's been several years since I looked at it for anything car/truck related.

 

well, debris left in an oil galley could certainly cause an oil starvation issue, especially at idle with the lower oil pressures all these new engines seem to run at. Really liked these new Tundras, hope they get it figured out and fixed for folks. Really crappy situation to be in for sure.

 

Indeed. I am skeptical of the debris theory for our Tundras. First, the problem is the same bearing in every case. What Toyota is saying is that this debris is magically positioned so that it goes straight to that bearing, and only that bearing, and doesn't clog the oil passages which would cause starvation, but instead gets captured in said bearing and gradually cause it to deteriorate over time, hence the failures past 20k miles. I don't buy it personally. Seems if there were significant debris it would clog oil passages and cause quicker failures.

 

I agree.

Toyota is only replacing the short block, meaning (hopefully) they are confident metal debris isn't circulating around the engine. I just can't see debris getting into the same one bearing, and not creating collateral damage elsewhere.

 

Actually, we don't know exactly what Toyota is going to do yet. They had been replacing short blocks as they failed but the new safety recall covers ~100,000 Tundras... with maybe more to be added later since the failures are mostly happening after 20k miles... and it says that Toyota is still developing the remedy to address all affected vehicles and that won't be made public until sometime in July. Being that is it a safety recall they will need a positive way to fix or otherwise ensure that all the affected vehicles are safe. It might even mean all new engines replaced pre-emptively. We'll see.


Meanwhile many of us are having second thoughts of taking long road trips.

 

If it’s circulating the filter would catch it. If the debris is in the oil passages it’s likely going to the bearings on initial start up creating a time bomb.

 

It really is bad. I've read that not only is the GX 550 having the same problems, but also the LC 300 too. So basically every vehicle using this motor across the world is now a hot potato. I had also read the motor is manufactured in both Alabama and Japan, and failures are coming out of both factories, so it has to be a design issue. Even repaired motors are failing. I'd say CAFE is mostly to blame, but then Toyota has had a miserable record of producing fuel efficient truck motors too, it's like their engineers can't even fathom how to design a fuel efficient motor for trucks.

 

I can see it. This is, of course, conjecture, but if the problem was with whatever automated system they use to flush the blocks after machining, it could very well miss the same spot on every block.

The Car Care Nut has something to say. Love this guy.

 

He's great.

And I reached the same conclusion as him: short block replacement bad. That's what Toyota has been doing until now.

If they long block/partial assembly swap for the recall, that'll probably disappoint all who've had the short block done already....... just not right on such a complicated engine

 

Yes, but I mean, let’s dive right in, and then let’s reiterate from earlier and dive in some more and when we’re done, we’ll dive in.

 

Dude wants toyota to throw a new engine in every tundra … not gonna happen
