To a limited extent, I agree with doublereeder2 -- it is not magic or wishful thinking. But I believe, as the instrument is blown in, that the nature and location of the vibrations has significant affect on the wood, in both the bore and toneholes. It seems likely that using extreme care in playing in tune can create a consistent vibration pattern in the bore and relevant toneholes and affect the wood, possibly in a beneficial way for your intonation concerns. No doubt there is a limit to the effectiveness of this long-term 'fix' process. It is at that time (and I suggested a year earlier) that one could consider tonehole or bore adjustments.
As for short-term fixes, in addition to the useful key height and screw adjustments recommended above, try not placing the bell completely on the middle joint, just putting it on enough for the Bflat lever to engage, and lengthening the entire oboe. This can lower the E (but may create other changes in your instrument's intonation). In doing that you may have to adjust the screws which affect the closing of the Bflat key and the resonance key (if you have one) on the bell. In addition to the adjustments which you should check mentioned by others, make certain that the Bflat resonance key is tightly closed when you are not playing Bflat. Although a floppy resonance key there will not raise the E (it can actually lower it, but in an undesirable fashion), it could affect the forked F.
And with any adjustments you make, check to see if you are favoring one octave of E and forked F over the other.
