Default Primary cover screws... Washers??

My cover as far as I know has never had washers for the primary cover screws.

Is this how it should be?

I notice there are indentations in the case from tightening the bolts down.

Tightening too tight?

Thinking of looking for some small copper or brass washers for them all. Notice a leak coming from on of the bottom bolts.

Also having issues preventing my Transmision drain plug from not leaking.
Threads seem okay although maybe worn, i was afraid i may have stripped it after trying to use a rubber o-ring and maybe tightend too much. In all honesty some aluminim came out this morning when i took the plug out. But I can screw the bolt in by hand and apply tightness.

I'm thinking for the drain plug( depending what I can find at my local hardware) of either, ideally a copper crush washer and then some kind of sealant. Or a paper gasket of some sort and some sealant.

And recommended sealant?

Thoughts?

Okay cool thanks! I got some Permatex High Temp thread sealant its similar looking to the loctite PST. Do you use a washer of any sort on your plug?
I did find that unfortunately it seems that I have damaged some of the threads for my drain plug,yikes. It won't torque down with a crush washer that I tried, but it will torque down with no washer.
I put on some tape and the permatex thread sealer and snugged it up. not sure if that's too overboard or not.

Will see if it holds, although I may have a bigger thread repair in the future, sigh.

IMO nothing will correct bad threads other than a proper repair, the Last thing you want to do is place a Tapered Pipe Fitting in there ‘that will surely invite a cracked case ‘, there are plugs that have a smaller plug within the larger plug, once in place you are only removing the small steel plug rather than disturbing the fragile aluminum case threads , do some research, others may chime in

Drain plugs.

Not sure which engine you have but early engines use a stepped brass washer. Most people ignore this special washer and install whatever they have handy.

Check the parts nook for your model/year and see if they [specify a washer. Use that one.

If you have access to a lathe or can find a shop that does you can get a slot milled on the underside of the head of the bolt & fit an O ring, also use plumbers tape on the thread.
I use washers on all my case bolts
