Hi guys,
My MCM-140 manifold had a lovely crack in it, and had to be replaced. The new manifold did not come with new end plate & water intake, so I removed them from the old manifold, removed rust, gave'em a nice new coat of paint, and now I'm ready to put them onto the new manifold.
The manual I have for the engine is great for details on attaching the manifold to the engine, but nothing for these end pieces, except a torque spec.

The end with the hose attachment is for raw sea water coming from the heat exchanger, and the other plate plugs the other end, forcing the raw water up into the riser to mix with exhaust gases.
Questions:
1a) Do the end gaskets need to be coated with sealant? (I have Perfect Seal and an "Aviation Gasket" goop)
1b) Same question for the riser elbow gasket to the maniold...sealant or no?
2) Here is a screenshot of the torque specs from the manual:

I'm assuming "end cap", for some reason listed singular, is the torque value for BOTH the end plate and the hose attachment end. Agree?
3) Here's a pic of my riser elbow...

The nice rusty nut at the front (left) is quite easily accessible with a torque wrench. But how do I properly torque the aft one in that little nook? I can only get to it with a regular wrench.
Thanks guys!
EDIT:
4) What about using Loctite...Yes or no?
