Here's the manual page for the water outlet. http://web.archive.org/web/201204051...67timingbe.pdf It gives the procedure you described.
Did you assemble it quickly enough? (I'm not professional-speed, so I use RTV) Torque it correctly? Could you have a pit/crack in the casting?

There is one important thing no manual will cover. Any time u open the cooling system like this, u really need to burp or bleed the air bubbles out of the system.
personally, i have the most success getting the engine warmed up so the thermostat is open, then sticking a rag over the radiator and overflow tanks, carefully slowly open the hot pressurised radiator and let the pressure eacape. start the engine with radiator open rev to 1500rpm, (this will push all air to the front of the syatem which happena to be the radiator top tank). And while revving at 1500, fill radiator to brim with warm water and cloae the cap. Dont add cold water, u risk shocking the system which will lead to a crack.
then, after all this, ensure the overdlow bottle is filled to halfway.

The big advantage of FIPG is that it sets very fast. Which is great if you need to get that vehicle out of the bay to work on the next one.
I'm not nearly quick enough, and I can let it sit overnight. So I prefer RTV. You shouldn't have trouble here.
The water outlet is also held with nuts, on studs. As you undo the nut, it could take the stud with it. You don't care, but to remove the timing cover, the studs have to come out, so you need to lock two nuts together to take out the stud.
The removable (upper) part has a groove to "hold" the gasket material. You'll want to clean that out too.

Read the instructions on the package to be sure, but with most sealants you re-install immediately. The longer you wait to refill and start the engine the better (with most sealants). I say that because I haven't used 1282 fipg

With RTV you want to wait overnight. https://www.permatex.com/products/ga...licone-gasket/ With FIPG (or Permatex The Right Stuff https://www.permatex.com/products/ga...e-gasket-grey/), 30 minutes is enough. As it says in the manual, if you use FIPG and it takes more than 5 minutes from applying to gently snugging the nuts, you have to start over.

There is a specified torque value (where would you find it?) You'd have to go WAY over that value to snap a stud. The value isn't too high; consider getting a 1/4" drive torque wrench https://www.harborfreight.com/14-in-...nch-61277.html just for all the fasteners with a 10mm or smaller head.
As AKWheeler hints, you'll get a better seal if you tighten the nuts hand tight, then let the sealant set, then bring them to torque. You don't want to squeeze out ALL the sealant.
