You replaced the camshaft seal but not the crankshaft seal when you did the
timing belt?  Was the old camshaft seal leaking?

Did you put a sealant on the threads of the longer bolts that hold in the
rear covers and the water pump?  Some of those longer bolts go into the oil
pump or some oil channel and you can get leaks around those threads if
they're not sealed, I believe.
