Foam pieces on engine?

I was poking around under the hood this evening and noticed some greyish greenish molded foam on the engine, guessing it should have been removed during PDI?

 

That is sound deadening material. Direct injection engines have it to limit the “ticking” noise of the DI.

 

Good to know - thanks!

 

Any issue taking the sound deadening material off back driver's side of engine? I accidentally broke the plastic brace that holds it to the motor replacing spark plugs. If it needs to be replaced, any idea on the part number?

 

Needed is a bit of a strong word.

The NVH dept put it there. You might get more noise without it, but it isn't going to make the truck fold in half.

 

Sometimes my Tacoma sounds like a pop corn machine.

 

Mine smells like hot melted butter.

 

That is a big relief...I was really hoping that wouldn't happen since I had heard of that being a problem.

 

My first mod was taking that shit off along with that top engine cover garnish.

 

I also took off the top engine cover. Keeps those intake runners cooler = more hp.

 

Anyone know the part name or number for the foam piece in OP second photo? I recently had work done on my fuel pump housing and Lifter and they ripped the foam so it doesn't stay in place. I'd like to replace it. Yeah yeah it's not necessary...well I like things to look the way they should.

 

The heat might eventually start tinting the paint on your hood in that spot.

 

Keeps the dirt off too-

 

Im not worried about that even for a second.

Been driving like this for like 5 years.

 

Just noticed this foam on my 2022 as it seems to be disintegrating and there was a big chunk loose in the engine compartment....

 

A mouse ate part of my drivers side foam insulation on top of the valve cover. Plus, a “tech” at the stealership also broke it in half.

 

I would replace it since it’s sound deadening material these engines make enough noise as it is.

 

That material is not reducing the sound enough to justify replacing it, certainly paying money. Let it be IMO.
