High RPM on highway

Show me this... because I've never seen that happen...

Specifically, a honda of nissian 4cyl maintaining 4k+ for much of it's life.

 

There are plenty of them. The modern Nissan Versa 5 speed manual runs about 3800 at 75 and 4100 at 80.

They have no power, so they have to do that. It doesn’t kill or hurt them.

another good example is the Miata. My cousin’s 01 5 speed is somewhere around 3750 at 70. That scales to over 4K by 80 also.

 

A "modern Versa" isnt a good example of a quality motor lol.

I've driven plenty of "economy" cars from the 90's and early 2000's, with automatic and manual trans and not a single one lives about 3k at highway speeds. Not. a. single. one.

Also, just for clarification, I'm not calling you a liar. I'm just saying I've not seen this personally.

 

To be fair, I gave two examples. An opinion on the Versa doesn’t change the fact that it leaves the factory turning 4k at 80 and it isn’t falling apart from it. I also listed the Miata which turns plenty of rpm as well. There are other Hondas that I could go find and post that I don’t feel like doing that for. You haven’t seen them, but I can assure you they are out there.

 

My brother had a 2001 highlander v6, and it ran a bit over 3k at 65 mph. He got only 110k miles out of it before the engine failed. Toyota put an extra gear in the transmission the following year to drop the engine rpm at highway speeds. Toyota had known they had an issue with those 2001's.

 

Something doesn’t add up. Highlander started in 01 and they used the same 4 speed from 01-03. The U140E.
All that aside, there is no proof that revs are what killed that one engine.

 

why dont you guys get together and call Mike Sweers and ask him if running at 3500-4krpm on highway damages these engines.. and record it so we can hear him laugh in your face.
its pretty ignorant to think any modern engine cannot handle those rpms for long durations of time.

Anyone with a brain will tell you running high rpm for extended periods with kill an engine, or certainly shorten engine life. Even the best built nascar cup engines running at 8k are pretty well spent after just 500 miles.

 

Dude you can't make blanket statements like "3-4k rpm will blow up your motor". It's simply factually incorrect.

 

Stop lol

 

ok. then out of the 1 million plus tacomas built since 2016 with the 3.5l engine . why isnt there thousands of people complaining about their engines that have failed? 3500-4500rpm isnt high rpm... 8k is... our trucks redline is well below that... this is a none issue..

 

Didn't say it will blow up, but will shorten life. You might even notice seals leaking before their time.

 

nope.

 

Idk, you read enough of them here on tw have for one reason, or another. All I can say is the majority of these 3.5's don't run at those rpm. Mine very rarely ever has, It's only here you guys are saying it.

 

What else can I say other than ignorance is a bliss.

 

what seals will start leaking?

 

Usually high rpm will affect the longevity of the valve, and main seals. Of course dirt will to. Keeping low rpm is a happy engine.

 

how many people have your heard of that have valve seals leaking on their 3.5 or 2.7 tacomas? even ones with 100k + miles.

 

so say you had the choice to buy 2 different trucks. one that had been idled for equivalent to 100k miles and one that had been driven from iowa to california over the mountains and back and for its whole life for 100k miles. which one would you choose?
