Narrative:
On takeoff in portland; received an engine pressure regulating valve EICAS at 70 KTS; and rejected takeoff. We cleared runway and taxied near but not back to ramp. While still running we talked to ground for permission to stay there momentarily. We talked to pdx operations and to maintenance. The EICAS went away as soon as we reduced thrust on the reject. We did not see which side was affected. Maintenance referred MEL and told us to try engine run-up. We did this with ground permission but not that high power. No additional EICAS. We said we would try takeoff again and had to get a new release for fuel. We tried another takeoff with same results and returned to ramp. It was not until later that we realized that the engine pressure regulating valve item was underlined and that we should have done 'block turn-back' the first time.
