Engine cover foam question

[virafp]

I just removed my engine cover to clean the throttle body, and noticed that there are three places that appear to have some sort of sponge/insulation/foam glued to them. Is this something essential and what can I use to replace it?

Any pictures of what it is supposed to look like?

Thanks

Not essential. Is it falling off?

What's an engine cover? . Leave it off, no benefit other than in the showroom. And it's a source of vibrations/noise.

Reduces engine noise, makes engine compartment look modern/high-end, will keep some dirt off engine (look at the dirt on the cover... that'd be on the engine)

About as important as floor mats and an ashtray, but on the pro v con list, keeping it wins out.

I posted a pic on here a while ago at someone's request. They were replacing the foam. I'm on my iPhone, and searching from this is useless, but I'm sure you can find the link.

I had some 1/2" thick white silicon foam sheet that I use on my r/c planes and replaced the foam pieces with that and Goop adhesive. The foam pieces were probably added in spots to keep the cover from rubbing and vibrating on the engine in certain spots.

I wouldn't lose sleep over it.

leave it off- best mod since the d light.

btw no appreciable change in engine noise w/ cover off imho. besides hundy is eerily quiet for a v8 truck. a little burble never hurt anyone...

I always thought it helped protect the hood from excessive heat. Hoods on past vehicles always needed extra buffing to maintain the paint on the hood. For those of you that have been running w/o the engine cover...any hood fading?

Ive had mine off for over two years... nada... not even the slightest hood fade.

I havent heard about paint fading, but an interesting thought.

I think the primary purpose is aesthetics. In some applications of the 4.7l, there is not an engine cover used. On some of the newer cars with high pressure injection and some louder processes happening in the engine, the thick foam in the cover can help with noise.

I took mine off in 2008. I haven't had any issues since with paint fade.

Leave the cover off.

Once less thing to take off when installing the blower.

Zero hood fading after 12 years in eastern Oregon and SW Idaho sunlight.

My LX has oem underhood padding. I cannot fathom a plastic cover doing much as a heat insulator.
