Not insurmountable, and I don't see why you can't remove yours and replace the sealing washer, or just add a little thread sealant to the existing washer.

Has anyone experiences with this? TIA I believe you've misinterpreted the instructions in 05-7800HA. It says that the tensioner must not be serviced but must be replaced as a unit. It also says that the seal must be replaced. If you have a leak, replace the seal. If that doesn't cure the problem, then the tensioner assembly must be replaced along with a new seal.
