I did a gear box seal repair kit last month on a 172, it was hacking out oil. doesn't take long to fit.
That's brilliant, but where did the kit come from!?
I know this is a common problem, but mine is now at the stage where I can see the spots on the my driveway and I've got a whine. I think it's leaking quite a lot now and I'll be topping up very frequently.
mgoode, do you have a link or even a part number for that kit? Has it worked for the past month since you put it on?
