This is not a very good sign really. if you rev up to about 4-5 thusand rpm (more than usual) while driving in a safe mannor of course and see smoke then you will find the piston rings are probably going. you might al;so want to take into consideration that your valve stem oil seals are all internal as well so no real sign of leakage.so could also be the culprit.

just about everyone does with either an old car or a new car with high mileage.how excessive? is oil consumption.well first thing is to check for oil leaks either underneath the motor or any oil lines feed into the motor .any major leaks would be pretty noticeable.if none are present then one would assume that your motor is burning the oil through the exhaust system .check to see what color smoke is coming threw the tail pipe.blue or black smoke indicates oil burning white will indicate engine coolant burning.in any case some color smoke is normal just depends on how much.so lets say your exhaust smoke is normal still could be burning oil just not a noticeable amount.on average you shouldnt have to add anymore than 2 quarts a month or every 1000 miles .depending on your driving conditions if you are having to add more than this there would be a leak some where or heavy color smoke.keep up on oil changes and always add lucas oil usually 1 quart its alot thicker than conventional oil so it reduces engine wear and will handle any small leaks in the engine components like the pistons and rings.if problem still present get to a dealer or certified mechanic as soon as possible good luck.
Another person (mountainman1) had this same problem with the HEI he found it to be a bad ground connection at the coil in the cap. When he would replace the module after replacing the cap it would make a new connection for a couple of days then go out again. I do not know if this is your problem but it sounds the same.
hi, sounds like valve stem seals are worn allowing oil to seap into combustion chamber, especially when parked up for long periods ie overnight, this is not drastic,more embarassing eh ?
Its quite a job and not cheap to do, if your not filling the street with smoke then dont worry too much. But it will very slowly get worse. All the best,Phil
