That was the MSDS not application instructions.
I am looking for how large of a bead to put, are there multiple torque stages?

The universal torque spec should do something. Tighten until the bolt strips out then back off one half a turn

The correct answer for this engine is 12 NM torque and the application guide for the RTV is a 2 to 3 millimeter wide bead of RTV around the perimeter of the sealing lip or flange with the bead running on the inside lip of the bolt holes. Working time is 20 minutes and let the RTV cure a minimum of 45 minutes before adding oil.

I guess Model A just felt the need to post something.

Interesting. Normally instructions are to go around bolt holes but ..... I guess ..... it's sort of okay, considering. I think covering the mating surfaces is better though. Think dirt and rust in the empty spaces.

5. Apply a continuous and even bead of silicone to one surface, first tracing the internal areas of the gasket configuration, then all surrounding bolt holes .....

Model A has given this advice before. Works for him, maybe not so helpful for others.

As a general rule if the pan bolt holes are not through holes I do not encircle the bolt hole with sealant.

That's why gaskets are better, full coverage of mating surfaces and no sealant plugging the bolt holes.

I was going back and forth about using a gasket instead but decided to go with RTV as that is what came out of the factory. The two factors that drove me away from a gasket were;
Adding a gasket changed the dynamics with torque settings and none of the gasket manufacturers supply torque specs for using their gaskets.
Also reported issues with gaskets splitting and oil pan bolts working their way out when using a gasket due to improper torque.

The torque for the transmission pan bolts is 105 inch-lbs (12 Nm), according to Haynes and others. People are using that successfully for regular gaskets, including Fel-Pro.

Haynes says 97 inch-lb (11 Nm) for the lower oil pan. That would work for a regular gasket as well.

It should depend on bolt size. M6x1.00x14 (transmission) vs M6x1.00x25 (oil pan). So 105 inch-lbs (12 Nm) should be fine for both situations, gaskets or RTV, depending on what the specific instructions are for the RTV.
