TJ Oil pan installation...forgot to seal the corners

Recently finished my first ever crate engine replacement for my 04 Sport and all was good until I noticed a dreaded oil spot on the ground. It is coming from between engine and transmission. Upon further inspection, it looks like the oil is coming out of the half moon rubber gasket that goes over the rear main bearing cap area at the rear of the oil pan. After review of the FSM, I noticed that I was supposed to put Mopar silicone sealant or equivalent at the corners during the install (so much for reading directions ).

Does anyone know if I am going to have to remove the oil pan and engine flywheel and transmission torque converter access cover to get this oil leak stopped? If the access cover has to come off, won't I need to pull the trans back far enough clear the line up two pins? Sure makes me wish like hell I'd read the instructions or done this once before! I hate having to do things twice to get it right!

If anyone has a shortcut outside of keeping the oil topped off and dealing with the oil spots, I'm all ears.

Note: This is a brand new crate engine, so I'm making the assumption that the rear main seal is not the issue here...Also, if you see this same post in JK forum, it is because I'm a bit forum challenged at the moment...maybe dyslexic...JK/TJ???

Closing this one out...I spent the day Saturday pulling the exhaust and then the oil pan. Thankfully, I did not have to remove the trans access cover or separate engine and trans. I just cleaned everything up good with brake cleaner, re-installed the pan with the required RTV (used Permatex red high temp) at the corners based on the FSM and the leak appears to be gone.

The FSM recommendation to make four guides from 1.5 inch x 1/4 inch bolts really helped in alignment. You cut the heads of the bolt and then cut a notch in ends for flat head screw driver. This really helped in the alignment of the pan with the gasket. Without them, I can imagine the gasket would have drifted all over the place. Quote for this job from the dealer was about $400 and took me about six hours to complete. Not a difficult job, but does take some time.
