Let us see what all you prius gurus think. Prius has been shuttering in the mornings Seems to have come back since it has been getting warmer outside. Also at low speed take off at a stop Then it smooths out sometimes code will show up as misfires only. No oil in the coolant or coolant in the oil. Coolant loss seems to be happening. Been trying to burp the coolant system. Oil has smelled like fuel for a long time. No white smoke ever just fuel smell in cabin if I turn off the recirculate button. Does not burn oil since levels are always stable without topping off. Took some pictures with a scope Let me know what you think. Images are left to right cylinder 1,2,3,4 http://www.RedBullet.net http://www.ProjectLithium.com http://www.Pulstar.com http://www.PlugOutPower.com

You have entered a club that requires no initiation fee and has wide diversity in its membership. The problem is trying to get out of the club without paying the piper. Classic head gasket symptoms in the number one Toyota year for the issue. Coolant loss is the secret handshake.
