It is pretty simple. The sealant residue is minimal. Don't use a scraper or a knife. Use silicone sealant remover if you can find it. Permatex used to market it but it seems scarce lately. Careful use of a scuff pad is an alternative. Use the M-B silicone. Apply it exactly as shown in the attachment. There is nothing to be gained from applying a lot of torque.
One caution - I have chased leaks on this engine and none came from the pan, even though I thought it did. I pulled and resealed the pan twice with no improvement. Clean the entire front seal area, pan, oil cooler and test port areas and make absolutely certain it is the pan. Leaks from the front seal can appear to be the pan leaking.

Thanks vinceC for the help. I guess I'll just let it continue to seep. If I need to take the engine out to just reseal it, I my as well drop in a e55 engine in it haha.

Thanks for input guys. I wasnt able to tackle this since its been very hot this weekend.
My oil pan leaks on the very bottom smaller section which has the drain plug on it. I dont think the engine needs to come out in order to reseal that section does it?

No. It is an easy job with just the front of the car raised. The upper, main section is a different story.

Anything related to transmission needs to be surgical clean. Doing work outside may not be the ideal thing with blowing dust etc. Just my 2c's....

As mentioned earlier, Follow the bead spec and location religiously.. You will notice the lower part downwards face has a few small round recess's and the upward face does not, if you apply the sealant to the upwards face which I assume most people do, than be carful it doesn't alighn with any of the recess's otherwise it will leak

Does anyone have the instructions on the order in which the bolts have to go back in. I heard you cant just randomly throw them back up, they habe to be tightened in a certain order

Yes sure can be done with regular corking gun just not as easily,I realized how much better the real deal is after trying it,i'd never go back.
As said there is no tightening sequence just do all up finger tight first then torque to spec. Also,try hard to avoid accidently letting the sealant separate once contact has been made, can be a bit tricky with one hand on the pan and the other trying to find bolt holes
