my 93 civic dx D15B7 is running bad when left at idle for a long period, and smokes white, but it will not run bad on a cold start and no white smoke. i first thouggt this to be a head gasket but it only smokes after 20 min of warm idle. suggestions please

nice sparkplug bone and does it burn any coolant or oil?

 

[puckman1325]

no milky oil or coolant, and i will do compression tests and coolant pressure to make sure.
