i bought my RX7 from a guy, and it smokes, under 80,000 miles, but it sat for 2-3 years, is this normal, it starts and runs fine, i haven't ran it much cuz i don't want to ruin it, plz help

 

when does it smoke? is it white or blue? hows the coolant/oil?

 

it is blue smoke, but like i said, it sat for 3 years, and it is during start up, starts to thin out while running down the road, the guy i bought it from said it could be a cracked ceramic gasket? i am new to rotary engines so yea.
