Is this valvetrain or injector noise and is it normal?

I know these 3.5 engines are noisy, and I know what the injectors sound like at idle. But are they all THIS noisy even while driving? Not sure if it’s injector noise, or valvetrain noise. Either way, is this normal?

Bump

 

Uhhhhhh, I don’t hear anything

 

All I hear is the bad minivan collector head v6 burble through a TRD exhaust.



So...


Normal.

 

Take it back to the dealer asap, its going to blowup. Seriously the engine and the truck sounds normal.

 

Injector noise. Normal.

 

From time to time, I am 'forced' to put E10 in the tank. It makes high-pitched cricket-like sounds. Matter of fact, I'm down to an 1/8 tank of 87E10... When I put E0(91) back in, no noises and runs a lot smoother.

 

Although I’m sure the sound isn’t as obvious to others through a cell phone video as it is to me, I kind of assumed it was normal. I’m still trying to get used to how loud these things are. Every other vehicle I’ve had I would assume the heads were about to come apart.

 

Thats even weirder. We only have e10 grades here whether 87, 89, or 92. No odd noises i've heard running 87 e10, and i've owned the truck since new. I'm wondering if its more mental this is happening.

 

Don't run sustained high rpm, and they won't.

 

I can't speak for the behavior of someone else's truck, but mine acts exactly as described.
You ever tried E0? Hopefully I can get this tank ran out today; then back to the 'good stuff'.

 

I've run non ethanol fuel when filling up in northern vermont, and coming back to connecticut. Truck seems no different except for a little better fuel mileage.

 

I couldn’t really hear anything that seemed alarming
