3.4L TTV6 Engine Failures (V35A-FTS) - Expanded Recall for LX and GX 550

[spwolf]

Can you explain this more?

It was equally bad before. What they are good with is 3-4-5 years later, engines are bulletproof.
First few years? There were always bad examples.

Again, I can write about those examples that I was aware since I was a dealer between 2002-2011.
But yes, millions of MZ engines were recalled in early 2000s... AD (4cly diesel) had huge issues in mid to late 2000s.

So Toyota was never bullet proof, just on average better than others. Probably still are.

New engines are highly stressed i think it was a disassembly video by carcarenut where the bearings were pretty messed up on the v35a keeping in mind these are metal and much beefier than those in 3ur engine which were actually polymer (plastic).

Funnily enough when the land cruiser launched people were more skeptical of the v6 diesel than the v35a due to that engine being hot v but that one proved itself reliable and has had far fewer issues mostly with cam timing in the early iterations which were fixed pretty quick and since haven't heard of any other major catastrophe

Diesels operate at lower temperatures so that hot V is more like a warm V. It's why diesels have been using VGTs for over a decade. Toyota diesels are also very undertuned in general. A modern diesel with the tech level of F33 should easily make over 80kW/L (like a base BMW N57) but it's only rated at 70kW/L.

I'm sorry, but BMW, Mercedes-Benz, Honda, GM, and even Toyota are examples of manufacturers that have built engines that have been bulletproof from the get-go. Why are we accepting the notion that engines should fail until their "3rd-4th-5th" year of production?

Yes but diesel engines are also usually stronger and last longer but than they started adding dpf and it's been a mess

There are several Tundra owners on their second or even third "new" engines. If you count the engine they came with originally, that would be 3 or 4 new V35A-FTS engines in one truck.
