From what I've heard it's non-interference.
I have the Toyota Harrier myself.

 

From what I've heard...

Thanks for sharing your opinion.

 

Great video, Frank.

We didn't get the 2MZ in North America, right?

From what I've been researching it appears one of the cams in the 2MZ (either in or ex, can't remember at the moment and don't have my notes with me - in?) has an extra ~2mm of lift.

Was curious if anyone out there knows whether it is interference due to that minor change?

 

I don't know about the 2MZ, but I did get A LOT of questions about the 3mz, so I made a interference/non-interference video for it, too.

 

The 1MZ-FE VVT-i engine is a 3.0-liter V6 gasoline engine manufactured by Toyota. It features Variable Valve Timing with intelligence (VVT-i) technology, which provides improved performance and fuel efficiency.

Regarding the question of whether the 1MZ-FE engine is an interference or non-interference engine, it is generally considered to be a non-interference engine. In a non-interference engine, there is sufficient clearance between the valves and pistons, so even if the timing belt or chain were to break or slip, the pistons would not collide with the valves. This reduces the likelihood of serious engine damage in the event of a timing belt or chain failure.

However, it's important to note that while the 1MZ-FE engine is considered a non-interference design, there can be variations in engine configurations and models across different years and regions. Therefore, it's always recommended to consult the specific vehicle manufacturer's documentation or a reliable source to confirm the engine type and whether it's an interference or non-interference design for a particular vehicle and model year.

This post sounded particularly robotic, but the final paragraph gives it away.

ChatGPT equivocates everything.

 

All engines are interference engines if you do not take care of them, the rod bearing fails and the piston slaps both the head and the valve past the block deck. It happens that way most of the time. Almost all modern production cars are non-interference that have a timing belt. I am not sure about timing chain, but belt for sure.

 

This one is proof that you don't need to be a generative AI to be vacuous.

 

Have you ever watched this youtube channel? https://www.youtube.com/@I_Do_Cars

It is fun to watch. It is full of just break downs of failed engines. If you haven't, you should watch a few episodes and see if you like it. I think it is entertaining to watch in the background while typing stuff out.

 

Oh FFS - can we not cut-n-paste chatgpt BS into random forum threads?!

It's muggle data for muggles with no depth. It's useless in the real world for humans actually getting stuff done.

Sorry, dealing with a bunch of AI BS at work and this touched a nerve.

 

I pretty much hate reading Quora and Reddit these days due to the fact that it seems chat bots pose a question and then straight up answer their own damn question. Why? It makes Quora useless to me. Same with stupid questions like "Why does rain fall down and not up?"

 

It might become an interference engine, with timing changing at higher RPMs. It is VVT-i engine.

 

No.
