Tru,
Good luck on the start up. You have been working on it long enough and now you should be able to enjoy it. Just take it easy on that gravel driveway and wait until you get on the pavement to really open it up.
You are right about RTV and I use some stuff called The Right Stuff that seems to be the best I have found for stopping leaks and sealing places. It stopped a tiny drip I had on my transmission on the Cobra that I had tried RTV on twice and it would start seeping after a week or so.
Now you are going to have to take Warren's place with descriptions of your drives and pictures.
