i just spent the better part of 3 months cleaning up and installing a 305 chevy motor in my 80 grand prix....the engine compartment is a 100 pointer easy at shows....anyway i started the motor up and have been driving it for about 4 days now and i noticed a little smoke when i start it up...i know bad valve seals...ok i can live with that ill just check the oil more often and add when it needs it...well i noticed to day i like blue smoke coming out of the tail pipe and when i reved it up a cloud of blue smoke......... im actully in shock...i took the motor out of a lowmilage car that was takin car of...i had sprayed some carb cleaner in it just perviously to noticing the smoke but i dont think its the cause....im sad...all the time and money wasted
