New Willys JT and no engine cover

I always throw mine in the garbage on day 1.

Must all be sitting on ships from China waiting to be unloaded......... so they decided to just do without.
Odd as usually those had to do with air travel being guided and diverted, and so on. There's a few videos out there on the impact on under-hood air flow and cooling.

also for noise, or so I've heard.

Non-engineers comment that they aren't needed -but then there's a reason Jeep and Ford and GM and others spend money on engineering and manufacturing of these things.

Non-engineer here, so... what's the reason? Couldn't be too big or they wouldn't be shipping them off without one, right?

Ford Rangers ditched them two years ago, along with the acoustic, sound-deadening glass, rear under seat storage, aluminum control arms, exterior badges, bed cleats, illuminated gear indicator, etc. Yet somehow they keep adding $ to the MSRP each year. If you haven't been in a new Ford Ranger, they are LOUD on the inside. At least Jeep adds standard features instead of taking them away. I couldn't care less about lack of an engine cover tbh.

Agreed - it's possible that the upcoming CAFE standards played a roll, or inflation (cost cutting) or whatever, came along and trumped the reason they are there.
It's often used to guide air flow and/or for sound control. A lot was changed on Jeeps and Jeep engines after Chrysler came along as mother and found more women were buying Jeeps and more execs were buying them and bitchen' about noise. Blocks were changed, timing chain dampers were put in place, covers where covers had never been, a lot of changes in air intakes and so on.
You and I don't give a rip about that - I love a truck sound - but the market wins.

Yes. See my prior post. Sound has a lot to do with it. Even air intakes are designed to minimize noise to an extent (without impacting performance "too much".
I noted a ton of changes to Jeep vehicles when MOPAR raped and pillaged AMC - and found women were buying more Jeeps, guys in suits, families and they bitched about engine noises. I can show how the engines of the 90s changed a lot just because of noise.

Without the cover, what’s to hold the manifold burritos in place?

I wonder if they did that to reduce mouse damage? The little critters just felt so secure in there.

A proper burrito creates its own gravity.

I found the engineering equation behind their removal of that piece.........

Years back when the motor cover first started showing up, there was some reason used, they were to keep owners little fingers off the motor/engine area. There were a few of us not installing the covers after the first major tune up service. Many customers then were at least looking up the hoods & this practice stopped quickly.

Many decades back there were nearly complete under body pans that mechanics would just forget to put back in place as it usually required another set of hands & a lot of screws .
Keep in mind these were sheet steel pans. Owners never really knew & so life was good & factories stopped installing underbody pans.

VW still likes to use plastic under the engine area for their TDIs but we all saw that all stopped cold, but for other reasons. Europe has a large collection of these plastic pan undercover & they will be replaced if you catch it as you pick up your car.

I would like to see the plastic cover gone. But at the same time, these engines are so much better & can last for years longer than that China Clipper Packard or even that hot 49 Merc V8.

Who knows this may be be beginning of the end of the plastic engine cover. So hang on to yours.
Hang it in the ''man cave'' right next to the glow at night Pontiac hood ornament .

I just looked. We are not installing engine covers on the 22's.

Mine had one, but doesn't anymore

Especially one from Taco Bell.....
