Oil Pan Frustration

I feel for ya, but it's all part of learning.
I suppose you could clean the gap and fill it with "the right stuff", but chances are that you won\t be able to clean it 100%, and the goo won't stick 1005, you still have this annoying leak, still have to take it apart, and now you got this goo to deal with.
Ok so when that happened to me;
I drained the oil,
took out two bolts at the back, and installed longer bolts, then took out all the other bolts. This allowed the front of the pan to drop down. I was able to coax the errant seal to rotate into place, then RTVd it into place, check the back and RTV it, then re-install the pan.
But I have headers so the pan drops down quite far. If you have a factory exhaust, this might be harder.

Your other option is to remove the timing cover, and get access from there. But that comes with it's own set of problems; namely trying to get the cover back into place, aligning it, and putting the right bolts back into the right holes. Getting the front two pan bolts out/in can be a challenge. I've done it a few times for to replace the chain, so it's possible, but I can't say that it is any easier or faster. As I recall, I had to jack the engine up a lil. Check your timing chain stretch, and maybe kill two problems with the same procedure. If you do this, glue the new gasket in place on the front of the block.
