The instructions that came with the Riffraff tools say to put the green Loctite sealant on the 2 vertical sections of the cup (located at the top and bottom of the cup). If the sealant is doing its job, I would think that coolant would not make its way to the bottom of the cup.
I agree that all bets are off if the engine is overheated. No telling what happens to the sealants. I know that my engine has never been overheated, so I can safely eliminate that as a cause. I don't think there are any issues with the cooling system, so I don't think the cup damage was caused by the coolant.

Yep, pretty close to the bottom, but there is a short cylindrical section. Doesn't the sealant go on that section and also near the top?

|ford_doctor||If you look at a cutaway of the cylinder head that shows the injector bore with the cup installed you would see that coolant certainly does surround the bottom of the cup with the exception of the bottom where it contacts the cylinder head and is sandwiched between the injector tip and the seat. Of course this question is totally irrelevant if the engine was overheated.|

If any fell into the cylinder, I am sure they are long gone by now.

|ford_doctor||So I went digging and asked around. This is more common than I personally was aware of but not of epidemic proportion. Check for any cooling system concerns and correct them. The brass cups suffer if the engine is overheated, nor do the brass cups like the newer coolants people seem to think are okay to use. If you can source stainless steel injector cups for this engine that should cure it of a repeat failure.|

|Absolute||It appears its not bellowed at all when I look at it. It looks like the whole bottom of the cone is gone. So it appears bellowed, but its just missing the portion up to the first gasket. Amazed none of that metal made it into the cylinder. Thankfully the metal is soft, so it would probably just burn up and probably no damage if it did. I have a camera that fits down through that hole to see, I would look for dents and damage to the top of the piston, may even be metal welded on top. Better get it out now if it did. Its easy to do without removing the head if you need too. PM me if you need to know the procedure to clean the top of the piston without head removal.|

|ford_doctor||I have one question: How were you able to remove that injector cup with it bellowed out like that?|

|Absolute||Its an offer, but I think Riffraff still rents it too, for cheap + shipping. So doubt anyone will need it. Looks pretty in the specialty tool drawer as well. Almost everyone says "whats that", giving me another chance to brag about how fun my build was. Lol, I leave the drawer open a bit , front and center, just so they notice it. Hahahaha|

Riffraff gave me one for free cause I spent a small fortune there doing my build. Free to all, gimme a PM if you need it.[/QUOTE]
That is a great offer but about a month too late for me

. Injector cup extraction and installation tools are a little beyond what I can make at home, and a crude tool is not a good choice for that job![/QUOTE]

We were talking about the injector cup tools - the only tools I have ever needed to install an injector are my hand and a rubber hammer.
I will generally try to make my own special tools if I can just weld up some scrap steel and maybe throw a little bit of threaded rod in. I have made a spring compressor for a C6 transmission, an axle spreader for installing differentials, and a crankshaft holding tool for Honda/Acura. I'm sure there are several others I am forgetting. Injector cup extraction and installation tools are a little beyond what I can make at home, and a crude tool is not a good choice for that job!

|Texkenusmc||Absolute you are right on the money. I try and make most of my special tools if I have time. Our get my boy to make it on his CNC machine at the wedding school.|
