I would change get fittings out so you can use the OEM check valves. The 980s leaked initially but I was able to snug them up in steps and they finally quit leaking. You have to be very cautious with the 11mm aluminum Tial valves as they are very easy to strip compared to the steel 12mm OEM valves. Since your turbos are out, I would change it out. Tial will send you the parts for free. I detailed the process here:

30NM is the torque on the OEM valves with the copper crush washer.

These are great turbos as far as performance and behavior on track, but I've had so many problems with the leaks, really hoping this solves it. Both of mine leaked substantially on initial install, constant stream coming out of the adapters even at idle which turned out to be an incorrect sized o-ring sent with the aluminum check valve adapters so Tial sent me the correct o-rings and they both still leaked but much less, didnt detect any new leaks until a dyno day and we noticed after doing some pulls there was puddles forming.. Tial told me to just crank the check valves down tighter. I was able to make one side stop leaking via excessive force (was worried that something was going to strip with as tight as I had them), but the other still leaked a small amount after driving but none at idle.

Yes, those are the Tial 11mm aluminum check valve housings. You have to take the OEM checkvalve assembly, disassemble the housing and insert the actual OEM check valve into the Tial housing. It's all detailed in the instructions you have pictured there. You can skip all this if you get the new 12mm inserts which allow you to simply use the OEM 12mm steel check valve.
Ok, will give Tial a call this AM - probably better to stick with steel in my humble opinion; strikes me that a failure or bad leak here could result in fire - fire bad, burn car...
