Gap at rear of oil pan?

[beermunk]

I noticed a gap that seems to be leaking a bit of oil on the rear of my oil pan. It's not the pan itself, but where the back of the oil pan where the rest of the engine would be. When I get home later this week I can post a photo. Just wondering if anyone had experience with this and if there was a low cost solution for it. It looks like there was at one time a bead of sealant that has come undone.

You didn't say which engine but every full gasket kit I get for a SB v8 has 2 different thickness rubber gaskets to go between the pan and the block front and back. I test fit to see which thickness to use and then run a bead of sealant. Someone may have used the thin one and filled the rest with sealant or the old seal may be deteriorating. Oil pan seals shouldn't be very expensive. (Intake seals are about $8 EDIT-- actuall closer to $10. found some for $12 at advance auto aka partsamerica.com) You can usually drop the oil pan without removing the motor depending on your setup. I remember doing a re-ring on a friend's 400 SB with it still in the truck.

sorry - it's a 307. thanks for the advice that sounds good. it leaks more after I just run it and I'd like to get it fixed. Also, i believe that I can get the pan out without taking out the engine.
