13B-REW Rx7 FD3S 1997 Engine Rebuild Torque Specs

So im rebuilding my FD3S engine since my apex seals blew out and most likely damaged both my housing and my rotor (just bought new front and rear housing + 2 new rotors with competitive bearings and compression is at .08 and 0 out of 100) and I cant find online what the torque weight should be for the flywheel nut, or for my pressure plate bolts for my clutch connecting to the flywheel, id like this information in preparation for my rebuild job since I have a deadline of two weeks to rebuild it.

Secondly I am curious, what is the sealent used to connect the oil pan to the lower engine block of a FD3S 13B engine? I see the sealent on videos everywhere but I can never find a product name or listing in a video for it, im very confused on what the sealent is and how it is properly used, if someone could help that would be amazing.

First off, wrong section.

Second, how did you search? I just Googled "rx-7 flywheel nut torque" and Google highlighted "350 foot pounds" right at the top. Also this is all in the shop manual -

Mazda RX-7 Reference Materials

You need the shop manual if you are going to do a rebuild. It has everything in there.

There are a number of RTV's you can use for the oil pan. Hondabond is an easy one, just use that and you'll be fine. There are a ton of threads on sealing oil pans.

Also, LOTS and LOTS of info on this forum on every aspect of engine rebuilds. The core engine is very similar to the FC so if you see something on the FC forum that holds true. In Google you can search for "search term site:rx7club.com" and it will give results for just this forum, many times it's way better than the forum's search.

Take your time and don't be afraid to stop and ask questions.
