Started violently shaking at 70mph. Cyl#5 broken valve spring

Could these valve spring failures have anything to do with third world contracts for valve springs? I see more and more complex auto parts mfg in countries without great tech abilities.

 

These motors are failing left and right.

I wonder how it would look if everyone who has a perfectly fine, working engine were to report; my engine’s working fine.
Just like any other issue, you hear about problems, but the majority are still fine.
The motors are not failing left and right, stop being so dramatic.

 

Perhaps we should start tracking the build date or partial vin info if this starts becoming a trend?

 

There's what, 7 million tacomas with this engine, how many Lexus's? Super small percentage of failures.

 

toyota corp is probably already doing this

 

I smell revised springs.... could be a recall or just a TSB....

 

No new Pro, just a scratched up fender and that’s it, c ya TW.....

Welcome to page 32

 

How do you know its a valve spring?

 

Exactly my thoughts. Thats what i said to this guy in another thread, after he said that 3.5s have way too many problems.

He has got the million mile 2.7

 

Couldnt have said it better.

 

Just found this thread. I'm having similar issues with my '15. This 3.5 doesn't belong in a truck. Looking for direction

 

Eddie? Is that you?

 

Everyone bitching about Toyota motors should sell and go get an ranger or colorado. Dont let the door hit you on your way out.

 

What?

 

I had the same issue on my 2020 around 150miles after purchase.
