Gerald,
you might want to take off your oil filter and take a close look at the bypass valve. Some reman companies take the valve out when tanking the block, some don't. Regardless, if the fiber disc does not seat properly when it's all back together, then you will get symtoms like you are describing. I remember Hud1 saying that he put a plug in to block off the bypass, and his symptoms are still a mystery.
If the disc appears eroded or if it sets cocked and not sealing, the net result is that you will need to replace the valve with a new one (preferred) or block it off with a plug. Don't try to repair it, it's not worth the headache.
