i think the egr is the oem one. i would get some aluminum elbows. not sure about the uim looks to me like its been done at least one time before but with all that crud who knows what failed. doesnt look like it was the lower to me, that looks like the aluminum replacement not the oem plastic. so it had to be something with the upper. when mine went at 60k all there was is oem replacement and it was as bad as the original. the dorman one i put on more recently was much thicker in the areas around the coolant and gasket areas and noticeably heavier like the whole thing was thicker plastic.

Also it can get cruddy looking, that is when the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup, if you get a really cruddy build up then some times that can be from mixing green coolants with ethylene glycol with the Dex Cool, some newer type of coolants are said to be Dex Cool compatible, but I'd never mix them just to be safe.
Some blame Dex Cool itself, but IMO the cause is usually owner neglect.
Still a lot of people will flush the coolant system out totally, and go with a green coolant like Prestone Extended Life, or Zerex G-05, whether you switch or not is up to you, I'd get that coolant system flushed out well, and put some fresh coolant in there when you are done.
Mine was in good shape, but the lip of plastic around the throttle body gasket was softened, and it fell apart as I was removing the throttle body gasket, it may have just been a fluke, but if that happens with you then you will be replacing it for sure, and you'd have already spent like 30.00 on the gaskets, which you will be paying for again when you get the full kit, because I have not seen the UIM sold without any gaskets at all..
As for the EGR Stove Pipe, that is the old larger one for sure, I would replace that.
One thing I noticed with your LIM Gasket, they used the blue gaskets from the Fel Pro LIM Gasket Kit on the side, I am almost positive that was for some other application, I believe it was for those with L67'*, on mine I used the orangish looking ones from the kit.
Then again that could have been the darker blue one that comes in so,e of the LIM Gasket Kits, if so then it was the right one to go on there.
So most likely it was the TB gasket and the coolant was being sucked in at the TB? Still, I don't mind tearing it all down to be sure and I can clean everything up now and get all that gunk out of there. Plus I feel better knowing that I have the leak taken care of. I will replace all the gaskets since I have tore it all down.
My main interest was if I needed to replace the UIM; if the current one is OK, then that is good and less money to spend.

Go ahead and try to clean that old UIM up, and try to remove the throttle body gasket, if the UIM cleans up well, and the throttle body gasket removes without ruining the the plastic lip of the UIM that holds it in, then just get the UIM Gasket kit, look the UIM over good though, you don't want to put it back if it has warped anywhere.
If it looks ok when cleaned, and stripped of the gaskets, then go ahead and get this.

I decided to just go ahead and get the Dorman 615-180 kit. The reason is that this job was done several years ago; not sure of exact date without asking the previous owners, and it appeared to have been leaking since the day of the repair. I don't think the new and improved redesigned UIM was used; the EGR stovepipe is the same size which is probably the original one for all I know. It does appear the LIM gasket was replaced since it is not plastic.
So, with the new Dorman 615-180 ordered and on its way, what LIM gasket part number should I order?
I am also thinking of replacing the fuel pressure regulator if the ones on this model also tend to leak and cause the same UIM explosion; I replaced it on my old 93 as a safeguard so am thinking the same here.

Update: Also purchased the aluminum coolant pipes to replace the plastic ones. The ones on the car appeared to have been replaced when the first UIM job was done but I decided to go ahead and get the aluminum set.
Question: why is there an edit button if I can not edit the post after five minutes? Contacting the Admin is silly, easier to just tack on a new reply instead of contacting an Admin. How about increase the edit time limit from five minutes?

I cancelled the order for the aluminum elbows; the Dorman lower intake gasket set contains them; Dorman 615-717. Is the Dorman lower intake set the ones I want to buy or should I go with another brand?

Is that the aluminum framed gasket set? And where do they say the elbows are aluminum?
Paranoid me has reservations about that set, at least until hearing from someone who has ordered it.

Pictures I'm seeing is showing the plastic ones. When in doubt, just go to Autozone or where ever and get your eyes on a set to verify.
Also, the edit feature has a time limit of 5 minutes for a reason. That is to keep someone from going back and changing too much information. We would rather you make another post showing the correction. It'* to protect the integrity of the information here.

OT: five minutes is too short. Yes, I can understand about keeping the integrity of the posts but even 30 minutes could accomplish that and allow one to correct any mistakes. Or even 15 minutes would be an improvement and accomplish the goal and allow a bit more time for correcting mistakes.

I did see a pic on Amazon, and RockAuto that showed that set to come with the aluminum coolant elbows, but that is most likely false, either way that gasket is plastic.
You want FEL-PRO Part # MS98014T for the LIM Gasket set, the MAGNUM Part # MS18144 gasket is steel lined, but I am not sure I'd go with that one, as I have not heard of anybody going with it over the Fel-PRO one, I don't think you want to be tearing it down and replacing it again if problems do arise.
I also suggest getting the aluminum coolant elbows, I was not lucky when I did my UIM/LIM, and I had to go with the old style, luckily it is not too hard to change them out if they ever leak.
As for your frustration with the 5 minute edit post limit, too many times people have started an argument with somebody, and then edited their post to make it seem like they never said anything to them, that is one of the good reasons for the rule, it is there more to protect you, than it is to anger you, also it is there to make the Admin/Moderator'* jobs easier.
