Glad to know your pulling the manifold. I would imagine a few of us were beginning to think that was the issue too. Go slow. Have the fsm infront of you. Pay attention to the sequence of tightening when it comes time.
And go easy as you unbolt. Have a length of pipe of whatever (folks will laugh but I have an assortment of different pipes leftover from an old vacuum ect that work like a charm to fit over various sized tools) to add to your wrench handle; nice even straight slow pulls.
Seems most say that air line is the hardest generally from what I've read. PB doesn't always work cuz they're so tight it can't get thru. Break the tension an 1/8" turn then spray more, ect. If they break it's the way it is, you won't be the first, folks will guide you thru the fix.
My machinist replaced the PO's ugly plugs w/ real set screws of some sort. I was surprised to see them. Way more professional looking.
Good luck and feel free to ask if you run into an issue.

Thank you @mwebfj60! I've been studying your work and seen those. I'll check them out again and save them.

Thanks for the advice @NeverGiveUpYota ! I started tonight and will take it slow.

I have to say that there is something so satisfying about taking out all of that spaghetti. It is crazy how much more room I feel like I have just by getting that stuff out of there. I know some of it will be back but there is still more to remove too.

I'm trying to organize all of my valves clearly so that when I put the ones I need to back on I know exactly where things go.

 

[UGA2018]

I do have a few questions that I thought I would throw out there...

In this picture you'll see one of the vacuum lines that went into the carb. There is this little valve in the vacuum line. I don't think I need to keep that after my desmog but can you guys confirm that? Thanks!

Last question...

My HAC looks hacked. When I took it out the bottom fell off. It looks like there is a ton of dirt and junk in it. I planned to keep the HAC on the truck. Not because I live at high altitudes but because I have a dream (probably 20 years from now) of driving it from Atlanta to the West and visiting every National Park.

So I probably don't have to have it but I would prefer to keep it on. But is this fixable? I couldn't figure out how to get the bottom to stay on and I was a little worried about jamming it on there too hard and breaking something else.

Thanks for your help folks!

You don't need to keep the little valve, probably just a splice. If the HAC valve checks good just clean it up, I used epoxy to glue the cover back on mine.

Thanks @mwebfj60 . Is there any good way to test HAC when it is removed from the vehicle?

More progress on my desmog tonight. It feels great to get some stuff out of there and make more room.

 

[UGA2018]

I have a few questions that I am hoping you guys at MUD can help me with.

Should I remove this bracket that is in this picture? I don't see any reason to keep it but thought I would make sure.

I got a little aggressive when trying to remove my air rail. I just turned the outer nut and was impressed that it was turning out of the head so easily. But then I noticed that the pipe was turning with it. Oh well! There goes that air rail.

I then tried to put a wrench on one nut and turn the other. I couldn't get them to budge from each other.

I've soaked them in PB for 3 days and will continue to. But if y'all have any more good ideas I'm all ears.

Thanks MUD for all of your help!

I did the same kit to mine about 3-4 yrs ago. I couldn't save the air rail either. I snapped off two of the nipples. Oh well. I still have all the smog parts in a bucket. I was thinking someone in a smog state might need 'em. My 2F ran much smoother after, and tuned right up.

Yes I figure the air rail is toast now. Once you snapped off those nipples did you just use a socket wrench to get the bolts out of the head? I'm thinking since my air rail is a goner I might as well snap those off and get the bolts out in a easier way.

I think I read you're at altitude right? If so, the vacuum port should hold vacuum and the other 3 shouldn't. If you're down below 2570' it's opposite.

The main tube of the air rail and nipples might be worth saving, you can braze in new little tubes if you ever need it again.

 

[jawjatek]

All of the nipples came out of the head with a open end wrench. They were tight but none were stuck.

bust(or cut or whatever) the pipes off and use a 17mm deep socket to remove the nuts.

I hadn't planned on taking the air rail off the day I did, I was just trying to get that darn hose off at the check valve(for air pump, which I removed a few yeara back) hose wasn't comin off so took a sawzal to the hose and in the process the vibration busted most the pipes off....which actually worked out really well. And I happen to have the(quite spendy) OEM air rail plugs (from a 3fe) So.....I ended up removing the rail that day, was very easy.

Well I'm glad that the main tube could be worth saving because that is about all that is left on my air rail. Those nipples are pretty fragile. Any one that gets that air rail off without breaking anything is my hero. That's hard to do!

Thanks @jawjatek ! That's exactly what I had to do tonight to get mine out. I still have the last one by the firewall to get out in the morning.
