This is my first post but I have been reading for years. Anyway I just recently installed a set of FF stage 1's a few days ago. On the restart I had a bit of hydrolock, and yes I did all preventive maintenance. Including removing the screws in fuel rail to let fuel drain out and using my shopvac to suck the rest. Either way after trying to start for 30 minutes I got it to start up but it idled very rough and produced white smoke. The interesting thing is that the idle smooths out and the white smoke disappears and the truck runs great above 1200 RPM. I have replace the ICP for good measure, and I just flushed and ran two bottles of Blue Devil as a diagnostic tool incase my head gasket my be ruined. Not a perminate fix but I thought if it is a head gasket it would reduce it some and I would have an answer. There are no changes so far and I need some help from you guys, THANKS!
