No fun, sorry to hear about that.

Leak from the valve cover should be pretty obvious. Look behind the T-belt cover and see if it's wet on the front of the head. Unfortunately given the amount of oil you describe and the conditions in which it emerged I doubt this is the source.

Hate to say it but if the whole belt is wet then my money would be on the crank seal. I actually never replace those seals preemptively -- with VAG motors, just about the only times I ever see seal leaks are where one has been replaced! Sounds like oil's running out of there and pooling up in the bottom of the timing belt....

Could you have put a nick in the seal bore when pulling the old seal out? Won't be a fun thought but unless you find another source for the leak I would pull all the T-belt components off again, pull off crank cog and yank seal, and take a good look in there. What did you use to install the seal?

At least you know you'll get a chance to really nail the t-belt procedure down, after doing it a second time....
