I have just replaced the head on 90 Vanagon with a 2.1L engine.  I have a leaky cylinder head nut.  I have tried 3 different sealants and nothing stops the coolant from leaking past the nut.  I can not see a visable crack, but the coolant just flows as if the nut were not there.  

Has anyone else had a similar experience, or suggestion to make?  I hate to have to remove the head again.
