Dave I am confidant that the continuing flywheel seal problems are one in the same and unfortunately only time will tell for sure. to make this a true test you need to change one thing at a time so dont change the flywheel unless you have a good reason to.

Now you say the front pulley seal was shredded and it is a syncro. I have seen more than once a non syncro seal installed with a pulley that still has a syncro seal ( lip) on it. This eats the seal as the pulley is installed

Call me again if you feel the need

going faster miles an hour with the radio on I remain
