I hjave just about got my TL2 with enclosure into operation so I will look for this problem.
I did have leaks coming out the back on my TL1 and I traced it to the cross slide. Coolant was running down the tool post and onto the space between the ways then running back under the cross slide and dripping off the back end. I solved this by putting a piece of plastic as a screen over the front.
There were lots of other places coolant splashed out and we made plastic screens for several of them but in the end also added plastic drip trays under the machine and empty them every few weeks.
A significant 'leak' occurred once and it was because the coolant tank was not pushed far enough under the machine. The coolant draining down the slope on the casting did not drop straight down into the tank it clung to the casting, went around the curve at the bottom and discharged at an angle missing the tank. The same thing happened on my TL2 when I tested the coolant setup yesterday and I had to lift the tank up on blocks to catch the flow effectively.
