You guys use silicone on pan end seals ?

Wondering how many guys, that know what they’re doing, lol ! Use silicone on oil pan end rubber seals ? I know about using it in the corners etc. But I was thinking about using aviation gasket maker to hold them steady in place and to try to prevent them from wiggling around while I’m on my damn back slipping the pan on.
There’s a lot of advantages to doing this stuff with engine removed. I know the right way to do it. But, sometimes you have to try to be clever, when times are tough, lol !
I know they should be dry. But, does anyone see a problem with this or has anyone done similar with no leaks ? Or is it best not to ? Taking votes, before tomorrow when I put it on, lol !

Yep, I use Mopar black silicone anywhere there's a transition between 2 gaskets and small block end seals.

Im talking about under the front and rear seal. In between timing cover and front seal and between rear seal and pan. Not where gasket ends meet. I think aviation gasket maker would be very good here as it’s a thinner substance. I want to do that and use black ultra in corners. Aviation gasket maker never dries as hard as Ultra Black. So, it might be not the wisest thing to use under the front and rear rubber seals. But, it seals very well and it supposedly is resistant up to 400 degrees.

I see. I didn't catch that. I think I used Aviation sealer between the front seal and the timing cover. Yes, I use silicone anywhere rubber and cork meet (or any other dissimilar gasket materials)

You could use anaerobic sealer as well.

Thank you, I think it will work. I’m just wondering how many guys put something under the end seals. This is my first oil pan, intake and timing cover replacement. Just trying to avoid doing twice. It’s a lot of work to do all 3, as I pretty up everything as I go along. Actually, last couple weeks I addressed everything that has fluids behind it. First rear axle seal too. I appreciate all input. You guys are making one nice Mopar B body, with no flaws. Ha ha

I did it many, many moons ago on a 455 Buick after replacing the timing chain. I was not about to drop the pan to replace the entire pan gasket. It never leaked a drop.
