Same engines, big difference?

[MudPuppy]

I noticed that there is a difference in these 2 engines. The '81 is AWD and the 82 is select. But that still shouldn't make this much of a difference, I wouldn't think.
Why does it look like the '81's bay is stuffed and the '82's has so much extra room?



'82 select


'81 AWD


And here is the '87's, it's pretty stuffed in there as well.

 Well the 81 has the big ol' York AC compressor and also has an air pump for the emissions while the 83 has the smaller Saden compressor and no air pump (pulse system after 81). Also looks like the 83 has had some of the stock emission lines/controls removed, but then again so has the 81.

Buds right, you will notice the lack of fuel canister and vacuum lines going to the sides, and it also looks like alot of the wiring is better hidden or ran or missing too, but everything else should be nearly identical.

It looks like a lot of the emission controls on the 82 have been removed. It should have an air pump, as pulse air wasn't introduced til 83. Its also missing the fuel vapor canister as Hawk258 stated, but its also missing the 3 solenoids on the valve cover, and its missing the water valve for the air conditioner as well.

Yes the heater shut off valve is missing.  The A/C will not work at peak efficiency without it.

Man, y'all must have some good eyes 
What all is needed back on the '82 for it to run properly?  No, emissions or inspections here.
Would like heat to work of course, AC would be nice but isn't really needed.
3 solenoids on the valve cover  ? I am lost there.

The '82 will be the one I am going to get back on the road. The '81 is for parts (poor rusty car   ).

[IowaEagle]

The three solenoids were part of the emission system and were bolted to the top of the valve cover.  You can see the mount for them on the '81 at the back of the cover.  Looks like all three engines have had at least partial smogectomies.  The '82 appears to have the standard motorcraft distributor cap.  A MIU upgrade or an HEI upgrade will be a good improvement.

Yep, my bad. '82 model should have the air pump. The pulse system was introduced in 1982 for the 83 models. Whoops.

I think the paint job has somthing to do with it too. The black one is the same color as the engine and all the hoses making it kinda blend all together looking like theres alot more engine...theres alot of black goin on there. The gold one allows the eyes to more easily distinguish engine from the body.....Not to metion what everyone else said about a few more hoses and a bigger A/C.

Is "smogectomies" in the dictionary?  If not, it should be.  It seems to be a common occurence with these engines.  I was introduced to the concept by Allend at the '08 meet at IowaEagle's.

Funny you mentioned that.  I added it to my computer dictionary yesterday,

[MudPuppy]

So the '82 isn't missing anything that is needed? From what you can tell by the pics?
Seems that the '81 and '87 might have more hoses, to me at least.
Which AC of the 2 is the better one?

[ammachine390]

Well, the fuel vapor canister isn't really necessary, but it does keep your car from smelling like gas. Also, your 82, is missing the vacuum reservoir for the heater water valve. Both should be located on the driver's side fender and can be seen in the 81 pic. As far as the air conditioners, I think either are ok, the nice thing about the 81 is that the York compressor does not need oil mixed with the refrigerant as the oil is separate. Some people use them as air compressors.

[MudPuppy]

Ah, (fuel vapor canister) that's the black thing on the driver side shock tower I take it? My TSM shows an upright can-type thing.
And what does the vacuum reservoir (for the heater control valve) look like? I can't seem to locate this in my TSM.
Are the vacuum motors on the breather neck crucial?
I would love to have an on-board air compressor, that might be worth not having an AC.
Is there somewhere that shows how to turn one into an air compressor?

[ammachine390]

A is the fuel vapor cannister.
B is the vacuum reservoir for the water valve.

What vacuum motors are you talking about on the breather neck?

For the compressor, just google onboard air york compressor.
