Why do people say to remove the plastic engine cover?

[konstan]

I was looking for something, and came across a thread where people were saying that the plastic cover (the one that says Turbo Power) should be removed and left on the top shelf in the garage.

Why?

Does it make the engine hotter?

Or is it just because they don't want to keep having to remove it to work on stuff?

The reason to remove the cover is for airflow over the top of the motor. this is only really important if the PMD is in the OEM location.

It's a personal preferance thing. I prefer to not have to take them off every time I need to do any thing on the top of the engine. I don't think the air flow is a issue. If your pmd is on the pump, it's not a matter of if it will fail, but when.
They do make nice wall decorations for my shop. I have 6 or 7 of them.

Yeah I know I gotta do the PMD relocation thing... Just havent decided if I can do it all in one evening or if the truck will be out of commission longer than that...

Get the extension,,Heat-sink, and PMD W/resistor, Then pull it in, and do it,, 1hr job. Done, Leave stock unit, in stock place.

I hate any plastic cover on an engine. I want to see the engine if I open the hood and not such a crappy plastic cover. It is an engine compartment and not a show and shine showroom ! Just my 2 cents. --- And I also agree with the airflowthing, etc.

Meh, doesn't bug me at all:

I prefer a clean, neat and tidy engine compartment. If that means I can use a "cover" to tidy it up, then bring it on. It also allows me to hide compoinents under it. This can be anything from a pressure sender to nitrous solenoids. No one knows what's in there, it's the whole "sleeper" idea (yes, there are a couple things hidding under mine, with more to come ).


Some people remove it for ease of servicing. IE: fuel filter changes, etc

Some remove it citing heat retention issues (nah, that's an "urban myth" that big insulated hood an inch above it is going to negate anything the plenum may effect).

Some people remove it because they want the enigne to look more "industrial" or like the look of metal versus the cover.

Personal preference thing is all it is...

I was first told by a stanadyne dealer that it actually helps airflow to the pmd while MOVING. Some air tunnel type thing.... (i could see it applying more with the 94-95 style, but not the 96 and up....) But when you shut the truck off im shure it holds in some heat. So just move the PMD. I like the look of it, but it is a PITA when you tinker with your truck all the time. For a while i would take it of, put it on, take it off. Since then its been off, but i havent been doing much to it, so i might actually put it back on...

Well, I'd like to have an extra to experiment with getting a good fit since I have the Balance Flow kit on now, so if anyone has the "square" style like what was on my '95 and they want to part with it, let me know. I might take it off your hands since I don't want to cut up my original one if/when I remove the BF kit. I actually think it dresses up the engine compartment and my PMD is on the front "skid plate", so it's just a cosmetic thing to me.

Air while moving may have some merit. Air while boosting would be harmful. Stock boost can melt the plastic wire conduits touching the manifold. Air after the cooling fan can be very hot. I wonder how the alternator survives - well it doesn't really.
