Oil pan gasket - wet or dry

[Surcouf]

Hello,
A few questions as I am trying to put my little bomb back together:
- Thé MM manual does not specify if the oil pan gasket should be wet or dry. Any recommendations?
- For all the oil pan bolts / screws, any recommendation on sealing them? Should these screws have washers? Flat or not?
- water jacket plates and screws: same question as before: sealant or not?
- for thé 2 flanges in the shaft: same questions: wet or dry?

Thank you!!

Here is the mecca answer from the website. Thank the Afourians.

The bolts holding the water jacket plate are tough to seal, and are a frequent source of leaks. This leads to the corrosion often seen on the block below the water jacket plate.
Studs sealed into the block are a big improvement, eliminating the leak paths around the threads of the bolts. Moyer sells a kit for this. You can also use stainless set screws, or cut studs from all-thread.

Thank you for your answers.

I keep seeing recommendations not to use lock washers, but use flat washers. And copper/brass flat washers for the water jacket plate.

is there any bolt on this engine where a lock washer should be used?
Thank you !!

A lock washer should not be used anywhere that the end of the "threads" are exposed to liquids. These liquids will move past the threads and then past the gap in the "lock washer", thus a leak.

A "star" type of lock washer can work in some liquid applications as they are "full circle" with no gap.
