It wasn't a complete seal blow out leak, but a pretty decent drip.. I would have to top off the reservoir every two to three weeks.. Had several pancake size wet spots on the driveway constantly..
Here's something that took me back a little,.. When I first pulled the cap the off the res... it was a bit tight.. I'm thinking "Oh no,..the cap rubber has turned to mush"..but much to the contrary.. The cap rubber was hard and firm... dry to the touch.. Closes thing to new rubber that I've seen.. I don't know about having it in your system constantly, but you don't have to.. Just put in a small amount, run it a bit,..get as much of it out as you can without break the lines.. And no more wet spots on the drive... And I can see out my kitchen widow where the wife parks on the concrete drive.. It's bone dry every time she pulls out...
OK, it's only been 6 months,. but still it's been 6 month...
I'll up-date when and if I hit the year mark...
AT-205 is a whole different animal compared to any "stop leak" you can buy at your local parts store..
