Long story short I had my 74ish 350 rebuilt around April and have had problems since. Its smokes like a freight train on the passenger side of the motor. It has duel exhaust. No H or X pipe so I know its the pass. side of the motor. Coolant is still green. Motor oil still honey brown. Spark plug gapped at .45 and all 8 look like the 4 in the picture. I took it back to the rebuild shop and he replaced the valve seals. IT STILL SMOKE on the passenger side of the motor. Mechanic said replace the accumulator on the back of the 350 transmission because it can suck in trans. fluid through the motor and make it smoke out the exhaust. Carb is a 600 Edelbrock. Please help because I'm about ready to park this Bit@h.
