Question about oil seal around dipstick on 360

If you can get the tube out easily, remove it and clean it with lacquer thinner. Inspect the tube to be sure it is not cracked. If all looks good, use a Q-Tip and lacquer thinner to clean the hole in the block. Use RTV on the outside of the tube and insert it into the block and leave it alone for 24 hours. At this point you should be good to go.
