Inner water jacket seal cracked

Inner water jacket seal cracked
I was assembling my engine got to the water seals and found two of them cracked at the seam.
I got them from Atkins. The other two are fine.

Here is the other one

I tried calling Atkins but they were closed. I really don't want to put assembly off till I/they replace them. Can they be repaired?

I talked to Atkins, Dan I believe. He offered to either have me return the bad seals and he'd replace them. Or told me how to make them work.
Silicone sealant on those areas once they are in place. It's the same advice a friend had given me. I had read about it in the past; some people buy the water jacket directly from the source, cut it and seal it themselves.
What I'll be doing, per Dan's advice. Don't use any hylomar or crisco in the suspect area. The dry spot will be the crack, which will of course be in the intake area. Dab a spot of RTV.

^Unfortunately I'm pressed for time. I start a new job next Monday and for a lil while I'll be working two jobs.
I'm letting the RTV "cure" a little while I assemble other parts. I think they're good but opinions are appreciated
What I did was lift the cracked area out of the groove, put a dab of RTV under the seal. Pressed the problem area in and wipe the RTV that came out off.
I put one on either side of the middle iron,that way they aren't facing each other.

Had the same thing happen when building an engine for a buddy. Called Mazdatrix (place he got them) They sent a box we with new ones in it and had us send the cracked ones back in the same box. They said there is a shelf life on them and we must have gotten the ones that fell down behind the shelf.
Hopefully Atkins is just as cool.
I should add, as soon as I moved them in the package we could tell they were cracked. For all you know those seals could be 20 years old.

I've got more time to think about it. The assembly hit a new snag. I found corrosion on my middle iron that I swear wasn't there before a couple days ago. Here's a link to that thread
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/middle-iron-corrosion-960023/
My concern about the new job starting isn't that I don't have transportation. It's that I'll be working two jobs while training at the new job. I wanted to get as much done before Monday as possible. Now I"m all out of days off till I"m working two jobs.
About patching them. Atkins said they patch seals with RTV all the time and Dan walked me through how to do the patch. I posted pics hoping someone who has done this kind of thing would chime in...let me know if I did it correctly.
Side note: some people buy the seals and cut them to length, seal them themselves and use them.
Atkins was very cool and gave me the option to either send them in for replacement or patch them. What with my indecision about what to do with my middle iron I may send them in.....seeing how I'm not gonna get much done between now and Monday anyway.

Id out new seals in personally. Your saying your not going to have time to work on your car with all these jobs....It's not going to grow legs and walk away. Relax it will be there when you have time for it. Don't rush anything. it's a car man. not life or death situation.

What with having to stop to get opinions on the middle iron and not getting the engine assembled on my days off. I'll send the seals back to Atkins.
Talked to Dan this morning. Unfortunately he won't send me replacements till he recieves the cracked ones. I offered to email him pics as proof but he didn't like that idea.

Same thing happened to me.
Buy new seals-get them sent out immediately., return the new ones, have them refund your card once they get the returns.

i'd have used super glue to reattach the broken section then apply silicone over the break as a seconday measure.
it will be fine though. just apply a second layer of sealant over the patch prior to assembly.
since no one else seems to have any faith i figured you could use some. the people who are skeptical, well they really have no clue just how fragile the seals are in that section anyways.

BUT I didn't get anything done on my 3 consecutive days off. My goal was to have the engine assembled and one of my two rear subframes dropped and the diff off. With that not happening I"ll just wait and do it in my free time. Not happy about it, but such is life.
