Just finished my ls1/t56 swap and have a concern. After bleeding the clutch, the car drives fine. However I have alot of brake fluid leaking where the bellhousing meets the engine block. The weird thing is that I still have the exact same amount of fluid in my clutch master reservoir, as if im not losing any fluid. Could it be that I have a "puddle" of fluid sitting in the bellhousing from the excess fluid that leaked while bleeding the clutch? Or is the slave definitley bad? I have only driven the car 11 miles, and it has been leaking for 3 days. I'd hate to yank the trans for no reason.

 

Do you have a speed bleeder installed or are you using the stock stub?

The stock stub allows the fluid to pool at the bottom of the bell and leak out over time
Pop a cover off and spray liberally with brake cleaner if it bothers you

It's not a leak if there is no change in fluid level. Ls1 hydraulics don't move much fluid so you should notice even a small leak quickly
