Rough idle - white smoke ? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

After sitting a while my engine idles rough and has white smoke comming from the exhaust, the longer it sits the rougher it runs and has more smoke, Both the rough idle and smoke dissapear after less than a minuite and the car seems to drive fine, There is no water in my oil and no oil in my water,could this be my injector o-rings? I had them replaced about 2 weeks ago and this problem just started a few days ago!!!

The car is a 95 with a ka24de

rule of thumb is, white smoke is coolant burning in your combustion chamber, or maybe just water residing in your exhaust

is the smoke sticking to the air like a cloud of smoke, or does it dissipate into the are meaning vanishing? Are you sure its white, or do you see bluish tint to it?

It pretty much dissapites into the air.

hmmm... doesnt seem like a to series of a problem. Not sure what is causing your car to idle rough like you say. Maybe you have a leak in a seal or a gasket some where.

just one more question about the smoke, hehe, does it look a little transparent, thin (not thick), has a clear look to it?

Its medium smoke!
The rough idling-running goes away when the smoke does.

Still have white smoke - rough idle at startup but I have no water in oil or oil in water, does not run hot and no smoke from radiator when I remove cap!!!

possibly beginning stages of a headgasket problem.
