Miles Posted October 5, 2002 Share Posted October 5, 2002 Recently my 350 sbc belches white smoke on start up. Is this caused by a rich carb or oil getting into the cylinders? It doesn't smoke once the car is moving or pulling away from a stop. Thanks Miles Quote Link to comment Share on other sites More sharing options...
Tim240z Posted October 5, 2002 Share Posted October 5, 2002 Miles, You may have a bit more of a problem. White smoke usually means coolant in the combustion chambers. Too rich fuel mixture will give you black smoke and oil will give you blue smoke. Tim Quote Link to comment Share on other sites More sharing options...
Miles Posted October 6, 2002 Author Share Posted October 6, 2002 Tim I'll pull the plugs and check for water. I only see the smoke when it first fires up. Thanks Miles Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 6, 2002 Share Posted October 6, 2002 Miles, let the engine set over night and pull the dip stick and look for microscopic water bubbles (a condition that appears mysteriously after my brothers borrows my pick-up) Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted October 12, 2002 Share Posted October 12, 2002 Blue smoke from bad valve seals has always looked awfully white to me. Pull the plugs and check for oil fouling/residue. Especially the plugs in the back cylinders (since they are downhill from the front). Quote Link to comment Share on other sites More sharing options...

Miles Posted October 12, 2002 Author Share Posted October 12, 2002 I agree with the valve seals after doing a vacume gauge check. I am debating taking the heads to a shop for rebuild or buying a set of performance heads. It's always something. Gas take started leaking at the vent line so it will take priority for now. Anyone out there have any problems with the removing/attaching the filler hose when the tank is removed? Thanks Miles Quote Link to comment Share on other sites More sharing options...
