2004 Mazda 6 3.0 oil leak

I had replaced the valve cover gasket on my Mazda 6 with the 3.0 engine to fix the oil leak. Unknown to me at the time, there is a hard to see gasket for the camshaft "end cap". The hardest part of this job is either getting the water pump pulley off or removing the forward bolt on this part. I had previously replaced the water pump, which required the pulley to be removed. Had I known at time, I would have done the valve cover gasket and this housing gasket at the same time.
