Taco Down:(

Head gaskets have been blowing on cast blocks for generations with most of them not destroying the connecting rod in the process as far as I’m aware of.

 

The hilux diesel conversion I have my eye on is a motor & trans from over seas that doesn’t require DEF. just costs as much as another truck pretty much, but I’d rather pay the crazy ass mechanic and freight than buy another vehicle from Toyota.

 

Or it's such a low failure rate that it is considered acceptable given the scale of production.

 

Yeah but in this case you would've basically hydro-locked the engine at speed, that usually means the non-compressible fluid in the cylinder bends the rod.

 

I find it very interesting that your 3.5 engine has failed, one month after you mocking me. By the way, one more of them 3.5 engines blew, in your truck.

 

Big time Bummer OP! Do you feel like you've exhausted all avenues with Toyota to get them to help you out? If so just try sourcing a motor from a junk yard or ?. One that has some sort of warranty.

 

sorry i missed that pic. That sucks!

 

The Japanese came into my old work to teach us Kaizen, it is certainly not what you think it is. The continuous improvement is in reducing cycle time, weight, less workers, etc. For example if you had a crossmember that was fully welded, had 10 nuts and bolts, and took 3 workers to assemble, the "improvement" would be a crossmember that was spot welded, had 5 nuts and bolts, and only 2 workers to assemble.

 

I had extended warranty so they are going to plop in a mystery salvage motor in for me that has 55k miles but with no maintenance history so hoping for the best. At a cost to extended warranty folks of $10,500 or so. As for Toyota, I’ve given them every opportunity to come look at the motor or pay the difference for a new motor (ended up being about $2300 difference) they declined every time.

 

No my engine did not blow. I'm getting a new cylinder head on Toyota's dime. But yes, I had a major engine component fail.
But there is still no validity in your post. Anything manmade can fail.
The 2GR-FKS has proven to be a reliable engine overall.
Considering it's in.


So again I'll ask again.
And yes I'm mocking you gain. I'd like to see the numbers that would support a comment of "dropping like flies".

 

Curious where you got those articles above? Seems more of an opinion article since no one except Toyota knows the failure rates.

The second paragraph makes it sound like the 2gr has had a ton of problems in the past. "many previous problems were addressed with updated parts"

You would think that if these internal engine failures were super uncommon that Toyota would help people that were having motors fail right over the 60k mark.

 

I don't have a dog in the fight here. However I wonder if the Atkinson cycle is actually by design from Toyota to keep the cylinders cooler by reducing the power density and thus extending the life of the aluminum block. It has been known for years that the head gaskets will fail due to heat cycles when the cylinders are not bridged to the exterior of the block. So I ponder if this whole Atkinson cycle is designed to hold the Band-Aid on longer.

 

I gotta go with @TRD-ED on this one. Nothing is perfect and sometimes mistakes are made. If 99.5% of the 252,490 Tacomas sold in 2021 had no engine problems, that would still leave 1,262 trucks with engine failures. It sucks for those 1,262 owners, but for the other 251,228 it's a rock solid engine. Focusing on the outliers is not a valid representation of reliability.

There is a (fortunately) small group of members who seem to take pleasure in bashing and add nothing other than self aggrandizement to discussions. Many of them don't own 3rd Gen Tacomas, or even own Tacomas at all any more. They rarely if ever contribute anything constructive. The last thing I would do, regardless of what my opinion was, is bash some poor guy whose truck is sitting torn down in a shop for weeks by telling him he was stupid for buying it in the first place. I really wish people would think of someone other than themselves and treat others with a modicum of respect and decency.

 

Not even therapists tell people how they should feel. Pump the brakes in that TRX of yours. Wonder how long it’ll last. Wonder how butt hurt you’ll be when it dies prematurely. Wonder how you SHOULD feel then.

 

No, the block material had nothing to do with it. The part that actually cracked is cast iron liner molded into the aluminum.

 

1000% and exactly what I have said eleventeen different ways. The “it’s so black and white” crowd conveniently puts on their rose colored glasses while their vehicles continue to behave themselves. If an exec at Toyota needs to eat one less lobster tail or take one less vacation for each of these engines, boohoo and so be it. It’s their baby and it needs fixing.

 

Think this may be a chicken and egg thing here. Are you sure the crack happened because the gasket blew or did the gasket blow because the liner cracked? Not that any of that really matters to you at this point but this is such an abnormal failure I'd bet on the liner cracked and gasket blew because of that.

Now why the liner cracked you got me.

 

US designed Toyota for US market. Has no bearing on Toyota global.

 

Good thing I’m not your therapist I guess. If my Ram dies I will be super butthurt but I also hedges my bets with the extended factory warranty knowing that it is not only a complicated truck but also built by FCA.

 

For all we know. .5% of tacomas could have engine issues or 15% or 12% or 8% or .25%.

The truth is none of us know how many of these trucks have engine issues/failures except for Toyota.

To be honest I am more worried about having a timing cover leak than an engine issues with mine. A $4000 leak repair job is a real kick in the nuts. My local Toyota dealer says they see A LOT of these repairs.
