1995 Water in oil after head gasket replacement

I have a 1995 Tacoma 3.4 with 92k 1 owner but sat in a barn for 7 years with hardly being ran. It blew the head gasket and I had it replaced but still finding water in the oil. Changed oil twice sense repair and only drove 200 miles or less it ran ok. Mechanic said the block wasn't cracked... What else could it be and does anyone know a badass Yota mechanic in DFW?

 

I am not sure if 95's had a oil cooler. If it does, it will be on the engine block on the passenger side. It will look like this http://www.japanesetruckdismantling.net/Toyota-Engine-Oil-Cooler-3-4L-V6-5VZFE-p/15710-62050.htm
It may be the problem. Only way to know is to take it off and pressure test it.
