Does all the old butyl tape need to come off?
Getting ready to leave on vacation tomorrow and noticed the vent in the cabover was leaking. I stuck eternabond tape over the old butyl tape as I was advised it was alright, but it didn't stick proper...

Personal opinion of one internet stranger: To do it right, you would need to take off the vent, remove the old sealant and Butyl as well as possible from the vent frame and the roof in order to get clean surfaces that will seal well, and put the vent back on with new butyl tape and probably self leveling sealant on top.
In the process you may or may not find that water has been getting in for a while and there is some internal damage to the roof structure.
For a quick fix ... maybe put a good helping of self leveling sealant around the outside vent frame and hope it seals it up until you have time to do it right. It needs to be reasonably dry for this to work...
Other opinions welcome, please
