Hey y'all, new to the group. Got ahold of a 05 3010 trans 4x4 and got it running. Did good till it got warmed up and started blowing white smoke. Had a local "mechanic" go through and did head gasket, valve seals, rings, etc. Checked heads and cylinders and supposed to all be good. But still smokes at temp, runs good at start up. Anybody run into this? Is there any chance it's something other than a crack in the block/head? I also bypassed the coolant line to and from the carb thinking that might've been the culprit.
