Smoke questions

I have a 88 IDI 7.3 that seemingly out of nowhere started blowing blue smoke on deceleration. Im thinking it could be my valve seals but it came on pretty quickly. I don't want to damage any thing so im afraid to drive it.Anyone know of a troubleshooting tip to pinpoint my prblem I would appreciate the input.thanks Jeff
